Comrades:

The national coal mine gas treatment and utilization work site meeting was an important speech in our careful study and in-depth implementation of General Secretary Hu Jintao and Premier Wen Jiabao's work on safety production. Coal mines and national safety production showed an overall stable and tending to turn for the better. However, the situation was still severe. State Councilor Jianmin came to the conference to implement the “ people-oriented ” scientific development concept, realize the strategic development of coal industry safety development, conservation development, clean development and sustainable development, profoundly expounded the significance of coal mine gas treatment and utilization, and clarified coal mines. The direction of safe production put forward requirements and further strengthened our confidence in the next step.

At the meeting, Comrade Zhang Guobao reported on the " Eleventh Five-Year Plan " and related supporting policies for the prevention and utilization of coal mine gas . Jincheng City Government, Jincheng Coal Group Corporation, Jiangxi Coal Mine Safety Supervision Bureau, and Songzao, Huainan, Fushun, Pingdingshan and other coal companies introduced their experiences and practices. The responsible comrades of the Ministry of Science and Technology, the State Bureau of Coal Mine Safety Supervision and the Coal Industry Association emphasized that some key tasks that the government should pay attention to in harnessing and controlling the use of gas should be emphasized. Next, relevant experts and scholars also want to introduce relevant new technologies and new technologies at home and abroad. The convening of this meeting will accelerate the realization of the two-phase goal of coal mine safety set by the Standing Committee of the National People's Congress and determined by the State Council. It will take two years or so for the coal mine to seriously reduce the number of major gas explosion accidents and will play an important role. enhancement.

I will mention the following two points for your reference.

First, pumping and then extracting is a permanent solution to prevent gas accidents and strengthen the safety of coal mine production. It must be strongly promoted.

Gas is the " first killer " of coal mine safety production . Since the founding of the People's Republic of China, 22 coal mine accidents have killed more than 100 people, of which 20 are gas accidents. In 2005 , a gas accident that killed more than 10 people in coal mines accounted for 70.7 % of gas accidents . 15 months of this year, the national coal mine involving a total of more than 10 serious accidents is difficult to 15 cases, in addition to 3 from the flooding accident, the other 12 are from gas accidents. The prevention of gas disasters and prevention of gas accidents has always been a top priority for coal mine safety and national production safety. The 12-character principle of “ first pumping, post-harvest, monitoring and monitoring, and settling by wind production ” reflects the objective laws and basic requirements for coal mine gas prevention and control, condenses the lessons of blood, and is a summary and summary of the practical experience of coal mine safety production. In particular, “ first pumping and then mining ” is a basic and key measure for the safety of coal mines and has to be resolutely implemented.

At the 81st executive meeting of the State Council at the beginning of last year, seven measures have been put forward for gas control. Under the guidance of the National Coal Mine Gas Prevention and Control Inter-ministerial Leading Group, relying on the joint efforts of various departments, local governments and coal companies, the national coal mine gas control and utilization work New progress has been made. "Strengthening comprehensive gas control, speed up the development and utilization of coal-bed methane," included in the national economic and social development "Eleventh Five-Year Plan"; "Several Opinions of the State Council on Accelerating the use of mine gas drainage" has been issued, supporting policies The measures have been successively clarified; CBM development and the prevention and control of coal mine gas major accidents have been listed as key projects in the national medium and long-term science and technology development plan, and some key scientific research and development efforts are being organized and implemented. While establishing and improving the coal mine gas monitoring and control system, a number of new drainage facilities have been built in various places. Jincheng Coal Mining Group introduced US technology and built 210 gas wells, with an annual ground pumping capacity of 180 million cubic meters. Jincheng took coalbed methane as a new industry, increased support, and built 60 gas drainage systems in 42 high gas mines , initially forming a commercial production and sales system. The gas extraction rate of Huainan, Jingyuan, Tiefa, Songzao and other coal enterprises in this area is relatively advanced: 45 percent; some coal mines, such as Fushun Laotai Mine, reach 83 percent, and Yangquan Minmetals’ large well reaches 81 percent, creating and accumulating experience.

However, we must also note that due to the influence and constraints of various factors, the overall progress of coal mine gas drainage and utilization in China has been slow. At present , the actual amount of coal mine gas in China is only about 2.3 billion cubic meters, which is less than 15 % of the actual amount . Small coal mines generally do not have a gas drainage system and basically rely on downhole ventilation. In the 280 high-gas and high-burst mines of key state-owned coal mines, 25 drainage systems have not been established; 255 mines with drainage systems have been established , and management and maintenance can not keep up due to the lack of matching projects such as roadways and drill holes. There are 42 mines with drainage rates below 20 % and 14 mines with less than 10 %. Even though some coal companies that work better, their pumping and utilization is still at a relatively low level, and gas disasters have not been fundamentally controlled. From a national point of view, drainage technology and technology are relatively backward, some major technical problems have not yet been solved, gas pre-drainage in newly-developed mining areas and new mines has not yet started, and the utilization rate of gas extracted is too low.

The convening of the on-site meeting and the related policies and measures introduced by the state have provided favorable opportunities for strengthening coal mine gas control and accelerating the development of coal mine gas drainage and utilization. We must conscientiously study and implement important instructions from State Councilor Jian Min, learn from and promote the experience of advanced units, and further intensify our work.

The first is to place gas management at the height of life engineering and resource engineering. Gas control and drainage utilization are strategic measures to promote the safe development, conservation, clean development and sustainable development of the coal industry. It is not only an important resource project, but also a life project that guarantees the safety of miners. It is necessary to raise awareness, regard gas management as the primary task of the current coal mine safety work, enhance the sense of crisis, sense of urgency, and sense of responsibility, strengthen the consciousness of implementing the “ 12-character ” principle, and adhere to the principle of first resorting to mining, governance, and utilization. All coal companies should correctly handle the relationship between coal mining, excavation and gas drainage. To increase production, it is necessary to increase the amount of gas to be pumped simultaneously; to excavate and replace mines that are in short supply and have insufficient pre-drainage time, it is necessary to adjust the mining relationship so as to ensure that the drainage is carried out first.

The second is to increase investment, strict standards, and establish a sound drainage system. Coal companies should earnestly implement the coal mine safety fee policies that the country has already defined, provide enough safety fees, and speed up the repayment of gas control and the use of outstanding debts. All high-gas and high-eruption mines must immediately build a drainage system; if the system facilities are outdated and operations are not normal, they must be renewed, improved, matched, and well maintained and managed to truly play a role. When developing and constructing coal mines, it is necessary to consider and build pumping facilities in an integrated manner. The gas content per ton of coal in coal seams should be reduced below the specified standards, or the extraction rate should reach a certain level before mining can be carried out; when expanding coal mine production capacity, The gas drainage capacity must be correspondingly expanded; when the coal mine production capacity is approved, the gas drainage capacity must be verified simultaneously. The Coal Mine Safety Supervision Bureau will work with relevant departments to speed up the formulation of specific standards for coal mining gas content. The State Administration of Work Safety and the Coal Mine Safety Supervision Bureau will cooperate with the National Development and Reform Commission and relevant departments, continue to do a good job in supporting key coal mines to manage major hidden dangers and safety technical transformation, and implement the 3 billion yuan support project this year .

The third is to solve technical problems and do a good job of demonstration projects. We will implement the key science and technology projects for coal mine safety in the National Science and Technology Development Plan, and actively implement key technologies such as monitoring and early warning of gas outburst mines, gas permeability in low-permeability coal seams, and other key technologies. Intensified research and design of gas pre-drainage and engineering practice. While studying and drawing on advanced international experience, we have fully taken into consideration the differences in the occurrence of coal seams and ventilation conditions in China, and selected and promoted advanced and applicable drainage technologies to pump underground and downhole. Drainage and goaf extraction combined to increase the drainage rate. Encourage coal mines to cooperate with scientific research institutes and institutions of higher learning to carry out research on gas prevention and utilization problems. Do a good job in the demonstration of the Songzao Datong No. 1 Mine, which highlights the mine gas management technology, the pressure relief and drainage technology of the outburst coal seam in the Hongling Coal Mine of Shenyang, and the demonstration project of Tongchuan Xiashijie Coal Mine gas and oil and gas co-existence spontaneous combustion coal treatment technologies, and popularize the iron method, Huainan, and Jincheng. The advanced experience of the comprehensive management and utilization of coal enterprises will play a typical model for guiding the way.

The fourth is to implement economic policy support and increase investment in the use of gas. National "Eleventh Five-Year Plan" and the "State Council on promoting the healthy development of coal industry" and other documents, it has drainage CMM utilization and development of coalbed methane industry has made guidance, provides for the principle. The "Several Opinions" promulgated by the General Office of the State Council have made specific provisions on relevant policies and measures. All regions and coal companies must conscientiously implement and use well-defined CBM industry policies and economic policies. In the trial of Shanxi's coal industry sustainable development policies and measures, the State Council has granted four economic policies: the transfer of mineral resources by local governments, the extraction of coal sustainable development funds, the extraction of environmental protection funds by enterprises, and the transfer of funds. These policies can be used to promote coal mine gas control. And pumping use. All localities can also learn from Shanxi's pilot policy and actively raise funds to solve problems such as low enthusiasm for gas control and insufficient funds.

The fifth is to intensify supervision and supervision, and to implement measures for coal mine gas control and safe production. Safety supervision and supervision institutions at all levels must implement the "Twelve-Word Policy" and implement the " first withdrawal and later acquisition " as one of the key tasks of current supervision and supervision work. The 280 mines with serious gas disasters in key state-owned coal mines are closely watched . If there is no drainage system or the pumping system is not sound enough and the operation is not normal, it shall be rectified within a time limit; if it does not meet the requirements within the specified time limit, production and production shall be stopped for rectification; gas disasters Seriously, if the rectification fails or delays rectification, it must be brought to the attention of the local government. Strengthen supervision and supervision of state-owned local coal mines and township coal mine gas control work. The Jincheng experience has been promoted. All local state-owned coal mines and township coal mines with a certain scale and serious gas disasters must also establish drainage systems.

In accordance with the requirements of State Councilor Jianmin, he insisted on "not overtaking, not exceeding limits, not overtaking," and earnestly do a good job of reviewing and sizing the production capacity of coal mines. Labor capacity is the basis and prerequisite for scientific management. At present, the management of some coal mines is confusing, and it is indeed time for non-resolving. The State Administration of Work Safety and the Coal Mine Safety Supervision Bureau, together with the National Development and Reform Commission, the Ministry of Labor and Social Security, and the Coal Industry Association, will, on the basis of in-depth investigation and study, provide normative guidance on the underground capacity of coal mines, or formulate new coal mine underground capacity requirements. Through capacity, not only can control the number of wells entered, effectively curb special major accidents; but also help improve the coal mine labor organizations, improve the management level, promote the mechanization of coal production, and promote the coal industry to take the road of new industrialization. Interference must be eliminated and resolutely pushed forward.

A large number of facts show that strengthening the basic management of coal mine safety has become a top priority. The Guidance Opinions on Strengthening the Basic Safety Management of Key State-owned Coal Mines jointly issued by the State Administration of Work Safety, the Coal Mine Safety Supervision Bureau and the National Development and Reform Commission, the Ministry of Supervision, the Ministry of Labor and Social Security, the State-owned Assets Supervision and Administration Commission and the All-China Federation of Trade Unions is the state-owned coal mine safety at this stage. Management work must consciously follow the normative documents. Industry management departments should use this as a basis to guide the safe production of key state-owned coal mines; safety supervision and supervision organizations should use this as a basis for supervision and supervision; state-owned coal mining enterprises should use this as a basis to establish and improve internal safety management rules and regulations and comprehensively strengthen And improve the basic management of technology, on-site, equipment, and labor organizations, and build an intrinsically safe coal mining company.

Second, to push forward the management of gas and rectify and shut down two tough battles to develop in depth, and resolutely realize the two phases of coal mine safety goals

Last year, the Standing Committee of the National People's Congress proposed and the State Council determined that it is necessary to strive to use a period of two years or so to significantly reduce the number of gas explosion accidents in coal mines; to strive to solve the problem of small coal mines in about three years. These two milestone goals reflect the party and the country’s high attention to coal mine safety issues, reflect the inevitable requirements for the safe development and sustainable development of the coal industry, and have obtained the endorsement and support of the whole party and the whole society.

(a) The two tough battles have achieved phased results, but the problems in the field of coal mine safety are still very serious and the situation is still grave. In the second half of last year, in accordance with the requirements of the State Council's "Emergency Notice" and the "Special Provisions of the State Council," the nationwide organization of coal mine methane control, rectification and shutdown did not meet the conditions for safe production and illegal coal mines " two tough battle . " With the joint efforts of local governments, relevant departments, and coal mining companies, two tough battles have achieved phased results: The investigation and rectification of a large number of hidden gas accidents has increased the overall ability of coal mines to resist gas disasters; the country closed more than 5,900 sites. Coal mines that are illegal and do not have safe production conditions have banned more than 10,000 illegal coal mining sites in accordance with the law , eliminating a number of “ traps ” that breed accidents and devour life from the source . In the first five months of this year , the cumulative total of coal mine accidents fell, and gas accidents also decreased.

However, since May, the coal mine safety situation has become more serious. May the number of accidents and the death toll rose 27.8% and 11%, respectively; 3 a death - serious accidents 9 people and deaths increased by 50% and 45.5%, respectively, of which the major gas accidents increased by 90% and 71.7% , to us once again sounded the alarm. From the middle of June, it has still not been significantly reversed. One of the important reasons is that some of the illegal coal mines do not have safe production conditions and illegal production continues to cause illegal production: Small coal mines that have been closed have not been completely shut down, and there has been a resurgence of fire; there have been coal mines that did not have the conditions to issue permits and certificates. There was a lot of muddleing; a lot of coal mine resources were not standardized, and coal mines that were supposed to be shut down were retained under the pretense of “ integration ” and “ technical reforms. ” Because the supervision was not in place, illegal mining also spawned a batch. This shows that the problems in the field of coal mine safety are still very serious, and the task of rectifying and closing is still very arduous.

(2) Solving the problems of small coal mines requires a clear goal and more practical steps. In the three years to solve the problem of small coal mines, the general arrangement is to complete the “three steps” of rectifying and shutting down, integrating technological transformation, and managing strong mines. The general steps are: the second half of last year and the first half of this year will be the first phase, mainly the closure of illegal and unsafe coal mines; the second half of this year and the first half of 2007 will be the second phase, mainly due to the closure of non-compliance with safety, resources, and environmental protection. Coal mines with coal industry policies will eliminate outdated small coal mines through resource integration and technological transformation. From the second half of 2007 to the first half of 2008 , on the basis of continuing the integration and technological transformation, we will strengthen basic management and comprehensively improve the improvement of small coal mines. Safety quality and development level. This idea and steps are also in line with the objectives of the current government's safe production work proposed by the "Decision of the State Council on Strengthening Safety Production."

Static calculation, across the country there are many small coal mines
