Summary of coal mine production safety work and future work arrangements

1. Summary of production safety work

(1) Coal mine production and construction situation

From January to October, under the correct leadership of the district committee and government, Under the direct guidance of the superior industry authorities, a good foundation has been laid for achieving the annual safety production goals.

Dongsheng District currently has 31 coal mines, including 18 open-pit coal mines, 13 underground coal mines (including

Shenhua Changhangou Coal Mine), and 6 local underground coal mines. Technical transformation has been completed and has been put into production; 4 are undergoing technical transformation; 2 are newly built coal mines. Nine open-pit coal mines have been put into production; four are preparing for comprehensive acceptance; five are undergoing land approval procedures but have not started construction.

(2) Earnestly perform safety supervision responsibilities and implement safety production responsibilities at all levels

According to the relevant requirements of the district safety committee and superior authorities for coal mine safety production, combined with the actual situation , formulated the annual safety production target management responsibility certificate and assessment details. The Coal Bureau signed a responsibility certificate with the coal supervision station and each coal mine. The coal supervision station signed a responsibility letter with the coal supervision personnel, and the responsibilities were broken down and implemented according to the In accordance with the requirements of the signed annual safety production target management responsibility letter, the mine shall be assigned to each person, and each person shall be responsible for contacting and guiding the safety supervision and technical guidance of the coal mine. According to the requirements of the municipal government documents, all underground coal mines shall dispatch one safety supervisor to each mine. Implement in-mine supervision, report potential safety hazards in coal mines in a timely manner, and urge timely rectifications. From the coal management department to each coal mine, safety management institutions have been established and improved to ensure that safety awareness, leadership, personnel and responsibilities are in place. Formulate and implement a well inspection system for supervisory personnel at all levels, clearly stipulate the number of times the coal bureau director, deputy director in charge of safety, coal mine safety supervision station director, deputy station director, and safety supervisors enter the well, and strictly implement the coal mine inspection system.

The chief and deputy mine chiefs lead the shift operation system, effectively realizing the implementation of safety work. All Jinggong coal mines are required to set up a leading group for one supply and three preventions, formulate prevention and treatment plans in terms of fire prevention, waterproofing, gas prevention, and roof fall prevention, and equip them with corresponding testing equipment to strive to be prepared.

(3) Increase daily supervision and key supervision, and actively carry out special rectification work on various safety hazards.

In view of the resumption of work in coal mines after the Spring Festival, the Safety Supervision Department of the Municipal Coal Bureau, the District Safety Supervision Bureau, and the Talahao Town Government carried out the resumption acceptance of production and technological transformation coal mines in the region. According to the differences between underground coal mines and open-pit coal mines, According to the actual situation, special inspections have been carried out in coal mines with major hazard sources, various safety hazards in all coal mines in the region have been carefully and meticulously investigated, and complete coal mine safety inspection files have been established and coal mines with safety hazards have been inspected. Supervise coal mines to conduct regular testing, monitoring, and elimination of major hazard sources. Through key supervision, coal mines are urged to further implement their main responsibilities for safety production, increase investment in safety, advocate the concept of safety culture, and improve intrinsic safety levels. In March and September, in order to implement the spirit of the city's coal work conference, 30-day coal mine safety inspections were conducted respectively. Through self-inspection, mutual inspection, and centralized inspection, coal mines were urged to conscientiously rectify the discovered safety hazards and weak links. . In the process of daily supervision, coal mines are urged to strengthen safety management and hidden danger management through the following ten measures.

1. Strengthen ventilation management. In accordance with the relevant provisions of the "Coal Mine Safety Regulations", coal mines are required to build permanent explosion-proof seals to isolate the goaf areas, prevent air leakage in the goaf areas, and form a complete ventilation system. 2. Strengthen roof management, install roof pressure detectors, and adopt a combination of anchor rods, hanging mesh sheets, shotcrete, etc. to support the broken roof. 3. In terms of mechanical and electrical management, ensure the stable operation of the dual-circuit power supply system, underground All electrical equipment must be equipped with protective devices to prevent safety accidents caused by power outages, leakage, and electric shock.

4. Strengthen the management of employees. In view of the weak professional and technical strength of coal mines and the mechanical equipment is in the running-in stage, strengthen the qualification review and professional training of technical personnel to avoid accidents caused by improper operation; 5. Strengthen the Management of construction enterprise qualifications, and strictly examine whether the qualifications of coal mine construction enterprises are legal and valid. If they do not have construction qualifications and management capabilities, they will be ordered to stop construction;

6. Strengthen the mechanical management of open-pit coal mines, During the loading and dumping process, vehicles are required to operate in strict accordance with the regulations to avoid accidents caused by mechanical collisions. 7. Strengthen the management of blasting operations and require open-pit coal mines to entrust qualified blasting companies to conduct blasting operations in accordance with regulations. 8. Further strengthen the supervision of fire area control and achieve healthy and orderly progress in fire area control. The District Coal Bureau signed a responsibility letter for coal mine fire area control with each coal mine, which effectively promoted the construction and management of fire area control projects and the progress of fire extinguishing projects. The stripping shall be carried out in strict accordance with the requirements of the "Coalfield Fire Extinguishing Specifications (Trial)", and any construction that does not meet the requirements of the specifications will be stopped. 9. Pay close attention to the prevention and control of toxic and harmful gases in coal mines, and improve the remote monitoring and detection system. The excavation working face of underground coal mines must be equipped with water exploration drills with a depth of not less than 50 meters. Strictly implement the principle of "exploring before digging, digging first, and treating first". The relevant regulations of "Post-mining" require all coal mining enterprises to increase the daily inspections of toxic and harmful gas detectors, and constantly prevent and control safety hazards of toxic and harmful gases. 10. Strengthen the safety management of goaf and fire areas, and organize all coal mines in the region to conduct detailed supplementary surveys for water, fire, and gas in old pits in this minefield and adjacent minefields. In particular, we must do a good job in mining planning near old goafs and goaf areas. , and formulate emergency plans for the investigation and management of hidden dangers and the prevention of various accidents, and clarify the procedures and methods for evacuation and rescue in emergencies. Open-pit coal mines and coal (well) field fire area control projects carry out stripping, mining and installation above the goaf. During operation, a drilling rig must be used to drill the front holes, and measures such as blasting, vibration, and sinking must be used to fill and compact the holes. Operations can only be carried out after ensuring that it is safe.

From January to October this year, a total of 276 coal mine safety inspections were conducted, and a total of 218 rectification instructions and notices of suspension of production and construction were issued, with the rectification rate reaching 100%.

(4) Do a good job in safety training and education for employees, improve and improve the vocational education and training system

Each coal mine organizes employees to conduct training and education based on actual conditions, and requires coal mines to Operators must hold certificates to work, and the certificate holding rate must reach 100%. Supervisors conduct regular and irregular inspections on the certificates of special coal mine operators. If they do not meet the requirements, they will immediately stop production for rectification. This year, a total of coal mine safety supervision and management personnel have been trained 35 people.times; 90 people.times of coal mine management technicians, and 1,200 people.times of special operations personnel participated in the training, which improved the professional level of coal mine supervision and management personnel and the skills of coal mine management personnel, and strengthened the Safety management capabilities and accident prevention capabilities of coal mine workers. During the safety activity month in June, safety management books such as the "Coal Mine Employees' Unsafe Behavior Manual" and "Coal Mine Safety and Quality Standardization Manual" were distributed, totaling more than 1,000 copies. Extensive use of bulletin boards, banners, slogans, etc. to vigorously promote various safety knowledge, accident prevention methods and self-protection related knowledge. The coal mine organization watched the safety audio-visual CD and carried out various forms of knowledge competitions, operating skills competitions and other activities. The coal mine organization Emergency rescue drills were conducted, which effectively improved the self-rescue and response capabilities of coal mine employees in accidents.

(5) Strengthen the construction of coal mine emergency rescue system to ensure coal mine safety.

Each coal mine has established an auxiliary rescue team. Each team has no less than 9 people. They are equipped with oxygen respirators, self-rescue equipment, tile inspection equipment and other rescue equipment and medical equipment, and have learned and mastered the skills of mining and excavation. , machine, transportation and traffic safety protection and underground first aid knowledge, requiring coal mines to organize emergency drills and summarize the drills, promptly rectify existing problems, effectively prevent accidents, and minimize casualties and property loss.

(6) Strengthen the inspection and management of coal mine equipment, urge coal mines to increase investment in safety technical equipment and facilities, and ensure the safety of coal mine employees and corporate property based on scientific management and modern equipment.

The working reliability of coal mine equipment is directly related to the safety of coal mine employees and the equipment itself. Only by conducting regular inspections of equipment in strict accordance with regulations can intrinsic safety be achieved.

With the modernization and informatization of mining equipment, the inspection and management of coal mine equipment has been set as the focus of this year's safety supervision work. Strictly prevent aging equipment and equipment that has been officially eliminated from being used in coal mines, and strictly require coal mines to increase investment in safety equipment. , to ensure the safety and reliability of mining equipment and monitoring and control devices. Coal mines are required to increase safety investment to ensure that safety investment is not reduced when the economic benefits of coal mines fluctuate. Appropriate funds must be allocated to improve safety facilities, update safety technical equipment, equipment, instruments, meters and other safety production investments to ensure that comply with the safety production conditions stipulated by laws, regulations and standards.

(7) Strengthen basic safety management and comprehensively promote coal mine safety and quality standardization.

According to the requirements of the "Inner Mongolia Autonomous Region Safety and Quality Standardization Standards and Assessment and Rating Methods Standards and Assessment and Rating Methods", organize and carry out "safe and efficient, intrinsically safe" and "quality standardization" mine construction activities. All technologically transformed coal mines in the region (including coal mines with single well retention and resource integration coal mines) must meet safety and quality standardized mine standards after completion of technical transformation. Supervise and guide coal mines to improve various safety production systems, do a good job in safety supervision at production sites, and eliminate various unsafe factors in a timely manner. Make preliminary preparations for the comprehensive implementation of safety and quality standardization management and further consolidate the basic work of coal mine safety. As of the end of October this year, 13 coal mines have passed the safety and quality standard preparatory acceptance, including 3 first-level coal mines, 5 second-level standards, and 5 third-level coal mines. There are still 3 coal mines planned to pass the acceptance inspection before the end of the year, and the coal mines are planned to meet the standard. There are 15 mines, and 2 underground coal mines are short of funds for technical improvement and the progress of technical improvement is slow. It will be difficult to complete the standards next year.

2. Main problems in coal mines

1. Improvements in mining methods have put forward new requirements for safe production. With the completion of the "three-year battle"

, the mechanization level of coal mines in the region has rapidly improved, and the production methods have undergone fundamental changes. This has put forward higher requirements for the technical capabilities and safety precautions of employees. The educational level is relatively low, the professional and technical strength is weak, and there is a big gap between the investment in production technology and equipment and the goal of achieving intrinsically safe mines.

2. Potential safety hazards such as unknown exploration conditions in old goafs, large areas of empty roofs, and coal seam fire areas formed in the past have put great pressure on coal mine safety production.

3. It is difficult to acquire and occupy land for open-pit coal mines, and the procedures for temporary use of land and forest land are slow, which seriously affects the progress of coal mine technology improvement.

Three. Work arrangements for the next two months and New Year's Day

(1) Further deepen the implementation of the responsibility system, strictly prevent coal mine safety accidents, and ensure that safety accidents are controlled within the target range.

Focusing on the safety work center, highlight the main responsibility of safety production in coal mines, further implement the safety production responsibility system, continue to improve the management and assessment system of mine safety supervisors, and increase the intensity of assessment management. Fully mobilize work enthusiasm and initiative, promote work innovation, fully exert the supervisory role, and ensure that safety accidents are controlled within the target range.

(2) Continue to carry out in-depth safety production quality standardization work and consolidate the foundation of safety production management. Coal mines that have reached the standards will continue to be assessed on a monthly basis, and safety and quality standardization work will be regarded as the focus of daily supervision and inspection and as the basis for year-end assessments. Coal mines that meet the standards and maintain safety and quality standardization for a long time will be given certain material and spiritual rewards to form a Incentive mechanism, select quality standardization demonstration coal mines, summarize and promote experience in a timely manner, guide coal mines that have not reached standards through typical guidance, and guide coal mines that have not reached standards to actively carry out quality standardization work, and promote the in-depth and comprehensive development of quality standardization work.

(3) Strengthen on-site supervision and inspection, find gaps and loopholes against safety and quality standardization, and carry out special rectification.

Further require coal mines to do a good job in the management of safety hazards such as goaf exploration, large-area empty roofs, and coal seam fire areas, implement safety measures, promptly rectify safety hazards, and strictly prevent roof, harmful gas, water, and fire disasters In case of accidents, we carefully organize training and drills on emergency rescue to improve the ability of employees to prevent accidents and ensure they are prepared. Based on the characteristics of coal mine production in winter, special safety supervision measures have been formulated to prevent safety accidents caused by overcapacity and overloaded production.

(4) Increase the inspection of coal mine equipment management, vigorously promote the construction of coal mine monitoring instrument calibration laboratories, and ensure the safety of coal mine employees and corporate property.

Conduct special inspections on the coal mine equipment management system, inspection and inspection implementation, safety protection facilities put into use, and the integrity of electrical protection devices, and strictly require operation and use in accordance with safety regulations. Strictly eliminate equipment hazards in a timely manner, strictly prevent "three violations", and ensure the safety of personnel, equipment and property. The reliability of coal mine equipment is directly related to the safety of coal mine employees and the equipment itself. Only by conducting regular inspections of equipment in strict accordance with regulations can intrinsic safety be achieved. With the advancement of coal mines to fully realize mechanized mining and coal mine safety and quality standardization, the inspection and management of coal mine equipment has been set as the focus of future safety supervision work, and aging equipment and equipment that have been explicitly eliminated are strictly prevented from being used in coal mines, and coal mines are strictly required to Increase investment in safety equipment and instruments, and require coal mines to establish monitoring instrument calibration laboratories to ensure the safety and reliability of mining equipment and monitoring and control instruments.

(5) Strengthen emergency production safety duties during the holidays, resolutely prevent coal mine safety accidents, and make a good start for coal mine safety work.

We attach great importance to duty work during the holidays, strictly implement the system of leading cadres on duty and the 24-hour duty system for key positions. We must follow the unified arrangements of superior authorities to effectively strengthen leadership, implement responsibilities, and comprehensively do a good job in production safety Accident prevention and handling work. Ensure the implementation of emergency resources such as emergency agencies, rescue team equipment, and supplies, and ensure that emergencies can be handled promptly and effectively in the event of emergencies. After the holiday, some coal mines that have stopped production have resumed production one after another. This is a period prone to accidents and high incidence. We must be highly vigilant, resolutely pay attention to safety production work, never relax for a moment, resolutely overcome paralysis and lax thinking, and prevent post-holiday production safety Accident rebound. It is necessary to learn lessons deeply, plan in advance, take action early, and take effective measures to strictly control the acceptance of the resumption of production of coal mines that have been suspended during the holidays. Coal mines are required to formulate plans for resumption of production and work and conscientiously implement relevant safety measures. Strictly implement the production resumption acceptance system, and coal mines that have not been inspected and accepted will not be allowed to resume production, and those who resume production without authorization must be severely investigated and punished. It is necessary to continue to carry out the "three actions" of production safety in depth, strengthen joint law enforcement, severely crack down on illegal production and construction behaviors, and consolidate the development trend of stable production safety situation.

In short, we adhere to the working tenet of "production must be safe, and safety can produce", sum up experience, draw lessons, sound the alarm, work hard, resolutely prevent and contain coal mine safety accidents, and promote the coal industry in our region Good and fast development.
