　　Li Fanrong, deputy director of the National Energy Administration, introduced the overall implementation progress of the oil and gas development project. Oil and gas development project is the only major national science and technology project organized and implemented by enterprises. Under the leadership of the CPC Central Committee and the State Council, and under the organization and coordination of the National Development and Reform Commission, the Ministry of Science and Technology and the Ministry of Finance, we will adhere to the innovation-driven strategy, practice the scientific and technological research mode with enterprises as the main body and Industry-University-Research as the combination, gather the superior forces of the whole society for collaborative innovation, strengthen the combination of projects and demonstration projects, and comprehensively complete the overall goals and tasks of the Eleventh Five-Year Plan and the Twelfth Five-Year Plan. The three ministries and industry experts spoke highly of the organization, management and implementation of the special project.

　　Since the implementation of the special project, significant progress has been made in six major areas, including onshore oil and gas exploration, onshore oil and gas development, engineering technology, offshore oil and gas exploration and development, overseas oil and gas exploration and development and unconventional oil and gas exploration and development, with remarkable results.

　　First, six major technical series and 20 key technologies have been formed, 13 major equipment have been developed and 22 demonstration projects have been built, and China’s oil and gas exploration and development has entered a new era of innovation and development.

　　The second is to ensure that China’s oil production is rising steadily and natural gas production is developing by leaps and bounds. The output of crude oil increased steadily from 185 million tons in 2007 to 198 million tons in 2016, and remained the fifth largest oil producer. Natural gas production rose rapidly from 67.7 billion cubic meters in 2007 to 137.1 billion cubic meters in 2016, making it the sixth largest gas producer in the world.

　　Third, it has promoted the construction of national innovation system and enhanced China’s oil and gas independent innovation capability. It has formed a high-level R&D team with 100 enterprises covering the upstream technology of the petroleum industry, more than 50 universities of the Ministry of Education and more than 20 research institutes of the Chinese Academy of Sciences. Construction of 9 national, 23 provincial key laboratories and R&D centers and other high-level innovation platforms. Related achievements won 3 national special prizes for scientific and technological progress, 5 first prizes and 19 second prizes, applied for 2,143 invention patents, formulated 185 national and industry standards, and registered 722 software copyrights.

　　Academician Jia Chengzao, the chief technical engineer, mainly introduced the great progress in the exploration and development technology of marine and deep natural gas in China. Through special research, China has made substantial breakthroughs in marine and deep natural gas exploration and development technology, discovered and built a number of large gas fields, realized the leap-forward development of natural gas production, guaranteed national energy security, and promoted social and economic development and the construction of beautiful China.

　　First, a series of international advanced natural gas exploration and development technologies have been formed, and a number of large gas fields have been discovered and built.

　　First, innovative development of major technologies for marine carbonate oil and gas exploration and development, the discovery and construction of Anyue super-large gas field with the oldest geological age, Yuanba deep reef gas field and Puguang high-sulfur gas field in Sichuan Basin, and the growth of carbonate natural gas reserves in Tarim and Ordos basins.

　　Second, the development of deep natural gas accumulation theory and exploration and development technology in foreland thrust belt, especially the conquest of major exploration technologies such as deep-seated wide-line large-scale seismic acquisition and prestack depth migration in complex mountainous areas, has expanded the depth of natural gas exploration and development in Kuqa thrust belt to 8,000 meters, and found six large gas fields with a production capacity of 26 billion cubic meters under extremely thick saline strata, ensuring the safe and stable gas supply of "West-to-East Gas Transmission".

　　Third, major breakthroughs have been made in exploration and development technologies of unconventional natural gas such as tight sandstone gas and shale gas, and unconventional natural gas has become an important part of China’s natural gas production. For example, breakthroughs have been made in key technologies such as tight sandstone gas accumulation theory and reservoir fracturing reconstruction, which has realized the effective development of Sulige large tight sandstone gas field, with an output of 22 billion cubic meters in 2016; Technologies such as multi-stage fracturing and industrial development of horizontal wells have supported the effective development of shale gas fields such as Fuling and Changning-Weiyuan, with an output of 7.8 billion cubic meters in 2016.

　　Fourth, China has made great progress in key technologies and equipment for offshore deep-water exploration and development, discovered large gas fields such as Lingshui 17-2, and successfully developed the first deep-water gas field in the South China Sea — Liwan 3-1.

　　Since the implementation of the special project, China’s natural gas industry has achieved leap-forward development, and the accumulated proven geological reserves have doubled, from 6.1 trillion cubic meters at the end of 2007 to 12.98 trillion cubic meters in 2016, and the world ranking has risen from 14th to 9th. The annual output of natural gas in China has doubled, from 67.7 billion cubic meters in 2007 to 137.1 billion cubic meters in 2016, and the world ranking has risen from ninth to sixth. The proportion of natural gas in the primary energy consumption structure increased from 3% to 6%, and increased to 8.3 ~ 10% at the end of the 13th Five-Year Plan. Make great contributions to China’s energy structure optimization and environmental improvement.

　　In addition, the exploration and development of offshore deep-water natural gas in China has made great contributions to safeguarding China’s maritime rights and interests and implementing the national marine strategy; It has cultivated new industries such as the development of unconventional natural gas resources such as shale gas and coalbed methane in China, such as the development of marine shale gas in the south, which has guaranteed the gas consumption of local industries and residents and promoted the development of local economy; The large-scale development of coalbed methane has become an important clean energy in Shanxi Province, and has made important contributions to the development of low-carbon and green economy.

　　During the "Thirteenth Five-Year Plan" period, we will further strengthen the theoretical and technical research on natural gas exploration and development, constantly overcome the bottleneck technologies of deep-seated onshore, deep-water offshore and unconventional natural gas exploration and development, provide technical support for ensuring the steady growth of national natural gas reserves and production, and promote the further optimization of national energy structure and the sustained and stable development of national economy.

　　Xinhua News Agency: Basketball originated in 1891 and was invented by American PE teacher Dr. james naismith. At the 1936 Berlin Olympic Games, the men’s basketball game was listed as an official event for the first time. Women’s basketball was not formally included until the 1976 Montreal Olympic Games. There are only two gold medals for men’s and women’s teams in the Olympic Games.

　　In the past 16 men’s basketball and 8 women’s basketball Olympic Games, the American men’s basketball team won 12 championships, the Soviet men’s basketball team won 2 championships, and the Yugoslav and Argentine men’s basketball teams won 1 championship each. The American women’s basketball team won five championships, the Soviet women’s basketball team won two championships and the CIS women’s basketball team won one championship. China’s best result in the Olympic Games is that men are eighth (26th Atlanta Olympic Games and 28th Athens Olympic Games) and women are second (25th Barcelona Olympic Games).

　　Rules of the game: The Olympic basketball game consists of four sections, each of which lasts for 10 minutes. If the score is equal at the end of the fourth quarter, one or more 5-minute overtime will be needed to continue the game until the winner is decided. There is no limit to the number of substitutions for each team in the competition; Pause in the first half, each team can get 2 times; You can get 3 times in the second half; At any time in each overtime, each team may have a timeout.

　　There are two kinds of violations of competition rules in basketball games: violations and fouls. Violations include: walking with the ball, illegal dribbling, punching or kicking the ball, returning the ball to the backcourt, and 3 seconds violation. In addition, it also includes the following:

　　5-second violation: the attacking player must throw the foul ball within 5 seconds; Or when being closely defended, you must pass, throw or dribble within 5 seconds; When the referee hands the ball to the penalty player, the player must make a shot within 5 seconds.

　　8-second violation: A team must make the ball enter the frontcourt (the opponent’s half) within 8 seconds from controlling the live ball in the backcourt.

　　24-second violation: Every time a player gets a live ball on the court, the team must try to shoot within 24 seconds.

　　Interference score: When the ball shot (free throw) falls in flight and is completely above the level of the hoop, the players of both sides must not touch the ball. When the shot ball touches the rim, neither team member can touch the rim or backboard, reach through the rim from below and touch the ball, and shake the backboard and the rim. If the attacker violates this rule, the basket will be invalid, and the ball will be awarded to the other side to throw the ball out of bounds in the extension of the free throw line; If the defender violates this rule, regardless of whether he hits the ball or not, the shooter (free throw) will be awarded points.

　　Fouls include the following situations:

　　1. personal foul: If a player who didn’t shoot is fouled, the non-foul team will throw the ball into the foul area near the foul place to restart the game. If the foul team is in the state of team foul punishment, it should be awarded two free throws to the players who have not shot, instead of throwing the ball into the bounds. If a player who is making a shooting action is fouled, if the shooting is successful, points shall be counted and an additional free throw shall be awarded; If you miss the shot, you will be awarded 2 or 3 free throws according to the location of the shot.

　　2. Technical foul: it is a non-contact foul, such as ignoring the referee’s warning; Violate the referee, technical representative, record desk personnel or team seat personnel impolitely; Use language and manners that offend or incite the audience; Teasing the opponent’s team members or shaking hands near the eyes of the opponent’s team members will hinder their vision; Deliberately touching the ball after it passes through the basket to delay the game; Obstruct the rapid execution of throwing the ball into bounds to delay the game; Fake a fall to fake a foul, etc. The penalty for the technical foul is to award the opponent two free throws, and then throw the ball into the boundary at the extension of the center line opposite the recording table.

　　3. Foul against sportsmanship: A player is not legally trying to grab the ball directly within the scope stipulated by the rules, and the contact foul is a violation of sportsmanship. After the foul, the opponent will be awarded a free throw, and then the ball will be thrown into the line at the extension of the center line opposite the recording table. If a player fails to make a shot, he should be awarded two free throws; A foul on a player who is shooting a basket, such as a middle basket, should be scored and awarded a free throw. If you don’t hit the basket; Two or three free throws should be awarded.

　　Notes for watching the game:

　　As the host, every spectator who enters the stadium to watch the game should watch the game in a civilized way and forbid vulgar words and deeds. Specific attention should be paid to the following points:

　　(1) Visitors should enter and leave the venue in an orderly manner, and only bring soft-packed drinks into the stadium. Don’t sit on the steps of the passage when watching the game.

　　(2) The audience should not smoke after entering the gymnasium; Don’t walk around at will during the game; The mobile phone should be turned off or set in vibration and mute state. You can’t use the flash at will, especially when the players perform free throws.

　　(3) When the host introduces the players from both sides one by one, the audience should applaud each player. When the national flag of the participating countries is raised and the national anthem of the participating countries is played, the audience should stand up and pay attention.

　　Beijing Science and Technology Daily, July 9th (Reporter Liu Yuanyuan correspondent Feng Yi) Can eating more fruits and vegetables really prevent diabetes? The latest scientific research gives the answer.

　　The reporter learned from West Lake University that Professor Zheng Jusheng from the School of Life Sciences of this school, together with more than 40 nutritionists in Europe, proved from the perspective of blood nutritional markers that eating more fruits and vegetables is conducive to preventing diabetes (this article refers to type 2 diabetes).

　　The study concluded that if you eat 66 grams of fruits and vegetables every day, the risk of diabetes will be reduced by 25%. This provides valuable suggestions and references for dietary guidance in the field of public health. The research results were published online in the British Medical Journal (BMJ) on July 9th, Beijing time.

　　"We have tracked and recorded more than 10,000 cases of diabetes in eight European countries, including Britain, France, Germany, Italy, Spain and Denmark, and compared more than 13,000 healthy people. From the perspective of nutritional markers, we found that eating more fruits and vegetables really plays a positive role in preventing diabetes." As the first author of the paper, Zheng Yusheng said.

　　In this study, the research team recorded seven kinds of nutrients in the blood of the experimental population, including vitamin C and six kinds of carotene. These seven blood indexes have been proved to be nutritional markers corresponding to the effective intake of vegetables and fruits. Generally speaking, the more fruits and vegetables are consumed, the higher the content of these seven indicators in the human body.

　　Through regular measurement and tracking, the research team found that the higher the nutritional markers in the body, the lower the risk of diabetes, which shows that eating more fruits and vegetables can effectively reduce the risk of diabetes. Statistics show that the seven nutritional markers have increased by a standardized unit — — The risk of diabetes will be reduced by 25% if you consume 66 grams of fruits and vegetables every day.

　　According to reports, more than 10,000 diabetic cases and 13,000 healthy control groups were screened from more than 400,000 people through nearly 10 years of follow-up, so there are long-term data to support the reliability and stability of the conclusion.

　　"Many teams have done similar research before. Some teams use questionnaires, which may have the subjective will of the experimenters, so there may be errors in the experimental results. The samples of other research teams may be only a few hundred people, and the tracking time is relatively short, so the statistical data is not representative. This study has a large sample of participants and a long experimental time, and it is of great significance in the field of public health to verify the results through a more scientific method. " Zheng Yusheng said.

I am a person who can hardly exercise. For me, standing is the most intense exercise.

Although I have long known that exercise has countless benefits, I have always wanted to take the first step, but when I see people around me who are struggling to exercise,Spend an hour or two sweating in the gym every day., who all want to back down?

However, watching a documentary recently actually made me take the first step of exercise, because it let me know that exercise is not a hard job at all!

The documentary also said: those who work hard in the gym for an hour or two are simply thankless. As long as you master the method,Just 2 minutes a week., you can achieve excellent fitness results!

The host of this documentary is?Professor michael mosley, a medical journalist(Dr Michael Mosley), he has always been a lazy man, and in the matter of exercise, he wants to?Spend the least effort?Get the biggest return.

Medical journalist Dr Michael Mosley.

In order to realize his dream, the whole BBC team is in full swing, accompanying him to visit sports experts in various fields and looking for?Super high efficiency?The exercise method. This process was filmed as the documentary The Truth About Getting Fit.

Anyone who wants to exercise but doesn’t want to work hard must not miss this documentary!

At the beginning of the documentary, Michael will?overturn?A popular saying: "You can stay young and healthy by walking 10,000 steps every day".

The idea of 10,000 steps first came from a marketing campaign more than 50 years ago. A Japanese company invented the "10,000-step pedometer", and while sponsoring the Tokyo Olympics, it relied on a sentence.10 thousand steps a day"The advertising words are deeply rooted in people’s hearts.

But do you have to walk 10 thousand steps to be effective?

In order to find out the truth, Michael consulted Professor Rob Copland of Harlem University in Sheffield, and he will arrange a controlled experiment to verify this theory.

Note: In order to make the public understand the BBC documentary,

Experimental methods with small samples and not rigorous enough are often adopted, but they still have certain reference.

He divided six people into two groups to take part in the experiment:

The first group (Gillian, Dave, Dai Lun): Walk 10,000 steps every day, unlimited speed, about 8 kilometers.

Group 2 (Nathan, Gary, Judy): 10 minutes three times a day,doubleAbout 3000 steps, about 2.4 kilometers.

In the experiment, both groups wore activity monitors, which could track their activities throughout the day and monitor their heart rates. Professor Copeland said that the increase in heart rate caused by exercise can?Strengthen heart and lung function, is an important indicator to measure the effect of sports.

After the experiment began, the members of the first group worked hard to achieve the goal of 10 thousand steps, because 10 thousand steps were too difficult to complete!

Of the three people, only Dave and Dai Lun managed to finish the task. Gillian washed the bowl and deliberately walked back and forth several times, but only walked more than 5000 steps in one day.

In contrast, the members of the second group are much more relaxed.

They met for a brisk walk, and 10 minutes passed quickly. Unconsciously, they easily completed the indicators.

On the one hand, it is difficult to move forward, and on the other hand, it is easy to reach the standard. What is the effect of their exercise?

Professor Copeland published?Surprising?Experimental results of:

Although the first group is more tired, the exercise effect of the second group is better.?better!

He explained that this is because the brisk walking adopted by the second group belongs to moderate to intense physical exercise, and the intensity is increased by 30% compared with the usual walking.

Comparatively speaking, although the walking time of the second group is shorter, the intensity of cardiopulmonary exercise is greater, so the effect is better than that of the first group.

Michael’s first discovery saved him 7000 steps every day.

But lazy, he is not satisfied with this! Last time he found out?More labor-saving?Movement, this time he turned to.?More time-saving?The exercise method.

He went to visit.?High intensity intermittent exercise(HIIT) expert Niels worrall.

Experts from worrall arranged for six white-collar workers to participate in a five-week exercise program.

Before the exercise, the six people first took an aerobic fitness test.

Aerobic fitness refers to human intake, transportation and utilization.?oxygen?The ability. People with good aerobic fitness will run for 1000 meters without breathing. On the contrary, people with poor aerobic fitness will be panting after climbing several stairs.

After testing aerobic fitness, Niels worrall asked these white-collar workers to do it on a spinning bike every week?3 groups of 40 seconds?HIIT training.

In other words, every week they only need?Exercise for 2 minutes. After five weeks, these people only exercised in total.?10 minutes.

However, five weeks later, when six white-collar workers took the physical fitness test again, their?Aerobic fitness?An average increase of 11%!

Worrall explained,

This is because HIIT can stimulate deep muscles.

Deep muscles are hidden around the bones of the body, which plays a role in coordinating the body and supporting the bones and joints. Ordinary exercise is difficult to involve, and HIIT can activate them.

In addition, HIIT can rapidly consume muscle glycogen.

Muscle glycogen is the sugar stored in muscle. When people exercise vigorously, the body will break down the sugar in muscle and provide energy for the body.

Worrall asked a white-collar worker to do three groups of HIIT for 2 minutes, and compared his muscle glycogen levels before and after exercise.

The results showed that his muscle glycogen level decreased.?24%?As much as, if you use other sports methods, you may have to?45 minutes?In order to achieve the same effect.

Finally, HIIT can also exercise the heart and lungs and improve the whole cardiovascular system.

HIIT is good, but it is not convenient for everyone to go to the gym to ride a spinning bike. In order to let everyone enjoy the benefits of HIIT, Michael specially invited Beth Philips from Nottingham University to design a set of HIIT training without any auxiliary tools.

This training takes a total of 5 minutes, namely:1-minute arm jump, 1-minute squat, 1-minute run, 1-minute arm jump, 1-minute squat..

You can also easily complete this set of movements at home, and the exercise effect is comparable to HIIT of spinning bike.

Besides HIIT,Strength training?It is also a very popular exercise method in recent years.

In order to find out?Have the best effect?The way of strength training, Michael came to Glasgow University, where sports researchers Stuart Gray and Nai Stefanacci are working.?Test weightlifting and light liftingWhich effect is better.

The experiment they designed was completed by five women. Before the experiment began, all the people took a strength test, and the researchers will record what they can lift.?maximum weight.

During the experiment, the participants lifted the dumbbells with one hand and the light dumbbells with the other, and both hands should be lifted until they have no strength. The hand that lifts light things takes longer to reach the fatigue point than the other hand. Their legs also had a heavy and light exercise.

For six weeks, they conducted two groups of training every week. After the training, they accepted the strength test again, and the results showed that:

There is no difference between lifting weights and light weights at all, and the muscle strength of both hands and legs is almost the same.

Their hands muscles have been strengthened by 18%-19%, and their legs muscles have been strengthened by 25%, and there is no difference because of the different weights on both sides.

After learning this result, five participants said that they would rather lift weights because of the short time.

Therefore, it is simple to save time by lifting weights.

Unlike strength training, running is the most popular sport because it doesn’t need any instruments and equipment and is very convenient to perform.

In order to explore the truth of running, Michael came to St. Mary’s University in London and asked John Brewer, an exerciser, about it.?run?The problem.

We always think that running will damage the knee joint, but is this true?

Brewer said,Running will not only hurt the knee joint, but also benefit it..

This is because the regular pressure generated by running can bring more oxygen and nutrients into articular cartilage.Conducive to cartilage repair and growth.

Michael, the host, found it unbelievable, so Brewer asked him to do an experiment to compare knee pressure.

In the experiment, Michael put a sensor on his knee, then walked a certain distance at the designated position, and then he ran the same distance.

Then, the computer will analyze the pressure on the knee when walking and running.

As can be seen from the above picture, although the pressure on the knees is greater when running than when walking,But it takes less time to cause stress.. Generally speaking, the time for running to produce stress is only half of that for walking, because people have longer strides and shorter contact time between their feet and the ground.

The blue bar represents the stress time caused by walking.

The red column represents the stress time caused by running.

In the above experiment, the total pressure on Michael’s knees when he runs is smaller than when he walks.

Brewer said that these pressures are completely within the acceptable range of the human body, because the human body structure can fully load walking and running. Imagine if our ancestors couldn’t run, how could they survive the competition of nature?

Whether it is to avoid or chase prey, people need to use the skill of running, which has been used to this day.

Nevertheless, if you run in the wrong way, such as running too fast, running for too long, running on uneven or slippery ground, you may cause injuries.

After visiting a number of sports experts, Michael has mastered four major exercise truths:

1. Walking 10,000 steps slowly every day is better than walking 3,000 steps quickly.

2. HIIT for 2 minutes per week can effectively improve aerobic fitness.

3, it takes a short time to lift the dumbbell to fatigue, which can effectively strengthen the muscles.

4. Running won’t hurt your knees.

Michael’s next stop is to visit a physiologist, Professor Sirsa Osullevin. He wants to know why some people love running so much.

Professor O ‘Sullivan said that people will produce endogenous pheromones when running. This kind of substance spontaneously produced by the human body is very similar in structure to the alcohol in * *, which will excite.?Positive mood, increase appetite, bring pleasure..

Besides running, other exercises can also produce endogenous hormones, which explains why some people feel uncomfortable without exercise for a day. Because exercise can really make people happy. Professor O ‘Sullivan believes that "endogenous pheromone" is one set up by the body?Incentive mechanism to encourage exercise.

In order to let Michael witness the power of running, Professor O ‘Sullivan arranged for three runners to jog.

After running, the endogenous pheromone in participants’ bodies increased by 30% compared with that before running!

Professor O ‘Sullivan explained that the endogenous pheromone produced during this exercise is within a safe range and can make people excited to the right degree.

After reading "The Truth of Exercise", I was eager to try, and immediately did a 5-minute HIIT exercise, and sure enough, I immediately felt High.

It turns out that,Exercise can also be a simple and happy thing!Friend, you might as well try it!

　　Xinhua News Agency, Changsha, July 13th Question: Why did the pig farm explode? — — Investigation on the explosion accident of illegal fireworks production in Liling, Hunan Province

　　Xinhua News Agency "Xinhua Viewpoint" reporters Xi Min, Xie Ben and Liu Fangzhou

　　At 4 o’clock in the morning of July 11th, an explosion accident of illegally producing fireworks and firecrackers occurred in a pig farm in Zhuhuashan Village, Banshan Town, Liling City, Hunan Province, killing five people and losing two people. According to investigators, the pig farmers involved have been controlled by public security organs.

　　Why did fireworks explode in the pig farm? Xinhua Viewpoint reporter rushed to the scene of the accident to investigate.

　　"No one expected that fireworks and firecrackers would be produced inside."

　　Recently, the highest temperature in Zhuhuashan Village of Banshan Town approached 37 degrees Celsius, and the meteorological department issued a high temperature warning. According to the local deployment, fireworks and firecrackers production enterprises have successively entered the high-temperature shutdown period.

　　At 4 o’clock in the morning on the 11th, a pig farm in the village exploded, breaking the silence at night. "In an instant, the window glass shattered and the fire was shining outside." The villager surnamed Liu, who lives more than 100 meters away from the pig farm, recalled to the reporter, "I thought it was an earthquake."

On the 11th, villagers were cleaning up the damaged doors and windows. (Xinhua News Agency reporter Xie Benshe)

　　The reporter saw at the scene that the aluminum alloy doors and windows of several surrounding villagers’ houses had been severely deformed, and thick glass crumbs were scattered at the door of the house, and the interior of the house was in a mess, and cracks appeared in the walls of villagers’ houses.

　　The reporter found that the pig farm where the explosion occurred was sandwiched between two mountains, and its geographical location was very hidden. The surrounding villagers said that there was nothing unusual in the pig farm on weekdays. In view of the hygiene regulations and the strong odor, outsiders generally do not approach. "I often see two cars parked at the gate of the pig farm at night, but only when someone comes to play mahjong, no one expected that fireworks and firecrackers would be produced inside." A villager said.

This is the scene of the accident filmed by the reporter on July 11th. (Xinhua News Agency reporter Xie Benshe)

　　It is understood that this pig farm named "Minwang Ecological Farm" has been operating in the local area for many years, and the legal representative is Liu Moujun’s wife.

　　After preliminary investigation, at the end of June this year, Liu Moujun rented a pig shed with only 60 square meters in the pig farm to Li Mouzhong, a villager in a neighboring town, for illegal fireworks production. They bought raw materials from other places, stayed up all night, organized workers to work all night, and were suspected of making small fireworks products commonly known as "foxtail".

　　An emergency management cadre who participated in the accident handling estimated: "The explosive that caused this explosion may be more than 100 kilograms." The relevant person in charge of Liling Public Security Bureau revealed that seven suspects, including Liu Moujun, had been under control and Li Mouzhong was killed in the accident.

　　Expose multiple regulatory loopholes

　　Fireworks and firecrackers industry is one of the pillar industries in Liling. The data shows that there are more than 170 registered enterprises engaged in fireworks production in the local area, with more than 100,000 employees.

　　Illegal production is the pain point and risk point of fireworks and firecrackers industry. "Illegal workshops often have serious defects in safety management and are extremely dangerous." A supervision cadre of fireworks and firecrackers industry said that the relevant safety production norms have strict requirements on the construction of factory buildings, physical isolation of production links, quantitative stacking of raw materials, and personnel holding certificates. For example, the amount of processed drugs should not exceed 3 kg at a time, and single-person single-room operation should be implemented. However, the hardware facilities and personnel quality of illegal workshops are far from meeting the requirements.

　　Although the relevant departments have made great efforts to control it, the illegal production of fireworks and firecrackers has been repeatedly banned. According to the statistics of Liling Public Security Bureau, Liling has detected 31 criminal cases of illegally manufacturing and storing explosives this year, and 54 people have taken criminal compulsory measures. In 2022, this group of data was 59 and 88 respectively.

　　Why do offenders take risks? A practitioner in the fireworks and firecrackers industry said that compared with regular operation, illegal production saves many costs such as investment and factory construction, safety management and tax payment, and the profit rate may be more than three times higher. The reporter learned from the public security and judicial organs that Li Mouzhong was sentenced for illegally manufacturing and storing explosives in 2021. When the accident occurred, he was still on probation.

　　Many practitioners and regulators have reported that many fireworks manufacturers have emptied their inventories, and some people "bet" on the good market at the end of the year and use the off-season in summer to "grab production". Another person from the regulatory authorities told reporters that the wages of workers who illegally produce firecrackers in pig farm workshops may reach thousands of yuan per night.

　　It is worth noting that there are security loopholes in the "two ends" supervision of fireworks and firecrackers in production and sales.

　　A number of emergency management department cadres said that although the regulatory authorities require raw material manufacturers to strictly verify the buyer’s safety production license qualification, there are many cases of "taking advantage of loopholes" in the operation level, such as hanging certificates and forging certificates. At the sales level, one of the usual means of illegal production workshops is to enter the licensed manufacturer through the back door to complete the transformation, or directly "fake" the outer packaging of the regular manufacturer, steal its safety production license number and flow into the wholesale market.

　　The accident also exposed some problems that illegal production workshops are concealed and difficult to supervise. The police of Banshan Town Police Station said that the illegal workshop hidden in the pig farm was hidden and only produced at night. The cadre in charge of safety production in Banshan Town said that he had never entered the pig farm for investigation before. This method of artificial production of firecrackers does not use large equipment and is very flexible. Once the raw materials and products are removed, it is difficult for regulators to find traces of production.

　　In addition, a cadre of the supervision department pointed out that some grass-roots units are not strictly responsible, and some even have interests involved. The investigation work is a mere formality, forming a blind spot for supervision and allowing illegal production to take advantage of it.

　　Be alert to risks in hidden corners and improve joint prevention and control at the grass-roots level.

　　On the 11th, the Emergency Management Department of Hunan Province held an emergency video conference on "illegal production" and safety supervision of fireworks and firecrackers in the province. On the 12th, Liling launched the "crackdown on illegal production" campaign, emphasizing "strict investigation, crackdown and strict control" on illegal production.

　　Liuyang and Liling in Hunan, Shangli and Wanzai in Jiangxi, four counties and cities are national fireworks and firecrackers industrial clusters, accounting for more than 85% of the country’s output, and are also key supervision areas for the production of fireworks and firecrackers.

　　Many cadres of public security and emergency management departments believe that the supervision of fireworks and firecrackers industry is polarized at present: the supervision of formal production enterprises is more and more strict and standardized, while the illegal production activities in "hidden corners" are more and more hidden, and there are signs of spillover to non-main production areas.

　　A cadre engaged in the supervision of fireworks and firecrackers industry said that in the past, illegal production dens were mostly located in abandoned houses and factories in remote areas. With the increasing crackdown, these dens kept changing places and their mobility was greatly improved. "Some are produced in high-rise elevator houses, and some are produced in the freight compartment of trucks, ‘ Shoot a gun and change a place ’ It is very difficult to find and attack in time. "

　　"The illegal production of fireworks and firecrackers also shows a trend of small-scale and fragmented organization production. For example, this pig farm den does not need electricity, machinery, and venues. The technical threshold is low, and a few experienced locals can engage in production. " The cadre told reporters.

　　The cadres of the emergency management department interviewed suggested that we should focus on the "two ends" in controlling and cracking down on illegal production — — On the raw material side, strengthen the crackdown on illegal sales of dangerous chemicals that are easy to explode, and strictly implement the management of raw material flow; On the sales side, strengthen the supervision and inspection of dealers’ operating compliance. In short, let the illegal production dens "raw materials can’t enter, products can’t go out" and cut off their interest chain.

　　On the other hand, we should strengthen the implementation of regulatory measures such as cross-regional inspection and joint law enforcement in the main producing areas of fireworks and firecrackers, accelerate the promotion of a unified and standardized management system, and carry out a "chess game" management of the flow of raw materials and products in the region.

　　The interviewed cadres also suggested that for illegal production supervision, the relationship between powers and responsibilities of various departments should be further clarified. We can explore the establishment of a comprehensive linkage mechanism between public security, emergency management, market supervision and other departments, strengthen command and coordination, and compact the supervision responsibilities of various departments, so as to form a joint force of supervision through continuous attacks on the upstream and downstream of the whole chain.

　　At the same time, it is necessary to promote the safety supervision force to extend to grass-roots safety supervision stations, village cadres, grid workers, etc., establish a normalized illegal production investigation mechanism, improve the joint prevention and control mechanism at the grass-roots level, increase the intensity of surprise visits and unannounced visits, and guard against cadres becoming "protective umbrellas."
