Coal mine safety production research report
Our county is a large coal-producing county. There are 60 coal mines in the county, including 20 with an annual production capacity of over 30,000 tons. The annual output is about 1.2 million tons, and the taxes and fees are nearly 10 million yuan. The coal industry arranges employment. Nearly 8,000 people, the coal industry has a vital role in the county's economic construction. Due to poor mining conditions in our county, it is difficult and costly, and coal production pressure is high. Since 2001, there have been 25 coal mine safety accidents in our county, with 31 deaths, a mortality rate of 8.86% in a million tons and a direct economic loss of 1,384,500 yuan. In particular, there were 12 coal mine production safety accidents in 2003, with 17 deaths and a mortality rate of 14.16%. The death rate per million tons exceeded the national, provincial and city averages, giving the county economic construction and social development. Brought tremendous pressure. This paper analyzes the accidents occurred in the safety production of coal mines in our county in the past three years, finds out the main problems existing in the current safety production of coal mines, and proposes the next work.
I. Coal mine accidents in the county from 2001 to 2003
From 2001 to 2003, there were 25 coal mine safety accidents in the county, with 31 deaths, a death rate of 8.86% in a million tons and a direct economic loss of 1,384,500 yuan.
II. Main problems existing in current coal mine safety production The main problems existing in coal mine safety production are as follows:
1. According to the analysis of accident categories, there were 23 roof accidents in the past three years, and 24 people died, accounting for 92% and 77.4% of the total number of accidents in 3 years. The gas accident was caused by gas explosion in Guangou Coal Mine of our county in 1994. A major gas explosion occurred 10 years later. The roof accident was prominent and the gas accident occurred again, indicating that the county's coal mine safety production work focus was not caught, and measures to prevent roof accidents and gas accidents were not in place.
2. From the nature analysis of the accident, the accidents in 3 years and 25 accidents were all responsible accidents. The accidents occurred due to the “three violations” of the enterprise personnel, indicating that the safety education of the employees in the coal mine industry in our county lags behind and the safety factor is generally low. Self-protection awareness is poor, and the consciousness of complying with safety production laws and regulations is not strong.
3. Analysis of the cause of the accident, the main reason for the roof accident is objectively due to the poor basic conditions of the coal mines in the county, the unreasonable layout of the wells and the insufficient safety investment. Subjectively, it is caused by the fact that the workers are not in the position of the work, or the support is not timely; some are caused by unreasonable measures and methods when dealing with dangerous rocks; some are caused by unqualified supporting materials. The main problem in the gas accident is that the inspectors are inadequately equipped, the responsibility is not strong, the inspection is not timely, there is no timely operation, and the underground electrical equipment has a detonation phenomenon; the coal mine dendritic mining has not been completely eliminated, and the ventilation is not very Good, gas is prone to sudden agglomeration, causing gas accidents. From the analysis point of view, the accident is ultimately due to the fact that the direct operator does not follow the safe production operation rules of the coal mine or the company does not have a practical, detailed and scientific operating procedure, which causes the practitioners to follow the rules or follow the rules. The management personnel of the company are also seriously irresponsible, and the basic conditions are poor, resulting in frequent accidents.
4. From the analysis of the time of the accident, among the 25 accidents, only 3 occurred before 10:30 in the morning, and 22 occurred after 10:30, that is, the management personnel at the enterprise site had to leave work, or Work safety has been caused by work or on-site management personnel who have not followed the work. It shows that the on-site management responsibility of the enterprise is not implemented, the supervision is not in place, and the workers take the opportunity to operate illegally. This is what we have neglected before summarizing and analyzing the accident.
5. From the annual analysis of the accident, the most accidents occurred in 2003 in the past three years, that is, when the coal mine industry has obvious benefits, grab production, and compete for interests, it is easy to have a safety accident, indicating that the business owner still has emphasis on production and light. The old problem of security.
Third, countermeasures
1. Further improve the understanding of coal mine safety production and firmly establish the idea of safety first.
Coal mine safety production is related to the safety of people's lives and property, and to the overall situation of reform and development and social stability. Doing a good job in coal mine safety production, effectively safeguarding the lives and property of the people, embodies the fundamental interests of the overwhelming majority of the people, and reflects the development requirements of advanced productive forces and the direction of advanced culture. Doing a good job in safety production is an important part of building a well-off society in an all-round way and coordinating the overall development of the economy and society. It is an integral part of the implementation of the sustainable development strategy and the basic requirement for the government to perform its social management functions. All departments at all levels in the county must regard safety production as a long-term and arduous task. The alarm bells will be long-lasting, often unremitting, overcome the war of war, paralysis and luck, and fully implement the important thinking of the "Three Represents" and safeguard the people. The height of life and property safety, from the full implementation of the spirit of the 11th meeting of the party in the county and the report of the government work, fully understand the importance and realistic urgency of strengthening the safety production of coal mines, mobilize all social forces, and jointly manage, Push forward with all strength. In particular, all coal mining enterprises must firmly establish the idea of safety first, starting from the aspects of investment in safety production, education and training, on-site management, etc., and strive to improve the safety management level and staff quality of enterprises, truly achieve production safety and reduce casualties. happened.
2. Resolutely implement the No. 5 Order of the State Administration of Work Safety and strive to improve the safety production level of coal mines.
The State Administration of Work Safety No. 5 made clear provisions on the basic conditions for coal mine safety production. Because most of the coal mines in our county are extremely thin coal seams, the layout of the wells is mostly unreasonable. The transportation, mining and ventilation facilities are relatively backward. Although the production was stopped last year, the enterprises have not changed much. To this end, the county coal, safety supervision departments and coal-producing towns and towns to further strengthen coal mine safety supervision and management, and promote coal mining enterprises in accordance with the requirements of the State Administration of Work Safety No. 5, further increase investment, comprehensively improve the company's soft and hardware facilities, especially in the promotion Transportation, ventilation, drainage facilities, etc. should further increase investment, and at the same time resolutely overcome local protectionism, and resolutely shut down those that do not meet the conditions, so as to strive to change the conditions for safe production of enterprises.
3. Pay close attention to safety training and strive to improve the safety awareness of business management personnel and employees.
At present, from the problems existing in coal mine safety production, the main performance is that the management personnel of the enterprise have a lack of safety knowledge, and there are many mistakes in the specific safety production management. It is impossible to make specific and scientific arrangements according to the actual situation of the coal mine. However, practitioners have lower self-sufficiency, poor self-protection awareness, and serious “three violations”. Therefore, it is particularly important to do a good job in safety training for business managers and employees. First, the competent department of coal mine industry and the comprehensive supervision and management department of safety production shall strengthen the training of the main responsible persons of production and business units, safety management personnel and special operations personnel in accordance with the law, and strengthen the laws and regulations such as the "Safe Production Law" and coal mine safety. The propaganda and education of production regulations will unify the qualifications and actual management standards, and truly improve the safety management level of coal mine management personnel. Second, the coal mining enterprises themselves must strengthen the training and education of employees, especially the actual situation of their respective coal mines. In accordance with the operating procedures, the training is carried out one by one, which really makes the workers familiar with the layout of the underground development, and can truly comply with the rules and regulations, and does not violate the regulations to ensure production safety. Thereby reducing the occurrence of casualties.
4. Strictly implement various systems to reduce the occurrence of casualties.
Safety production responsibility is more important than Taishan. To fully reduce the occurrence of casualties, it must be strictly managed. We must conscientiously sum up the successful experience in coal mine safety production in recent years, and we must also see our weak links, especially in the implementation of the system. For this reason, we must do a good job in furthering the actual development and improvement of coal mines. Coal mine mining operation procedures, and in accordance with the requirements of the regulations to effectively strengthen the responsibility of the relevant management personnel, and truly operate in accordance with the regulations. Every production enterprise must formulate and implement various rules and regulations in accordance with relevant laws and regulations, and truly achieve "daily monitoring, weekly report, monthly analysis", that is, "daily monitoring": every day on-site management personnel for each production link, Every period of production must be monitored and managed to detect and correct various violations in a timely manner, while ensuring that workers do not go out and management personnel do not leave work. Change the problem that the former manager only had a half-day shift or did not follow the shift. At the same time, we must have written records on the daily work situation and report to the mine leaders. “Weekly Report”: The deputy mine manager in charge of safety production shall timely sort out and summarize the work of each week and report it to the mine manager and relevant competent authorities and township people's governments. “Monthly analysis”: The company’s mine manager will convene relevant personnel every month to conduct a serious analysis of the safety production situation of the month, propose rectification of existing problems, and arrange for next month’s work to truly achieve safe production. Establish a strict safety inspection system and make every effort to rectify potential safety hazards. On the one hand, enterprises should pay attention to safety production. It is necessary not only to strengthen the investment in hardware equipment for safe production, but also to check the daily safety production, especially the ventilation and gas management of underground mining hoes, blind lanes and waste roads. The management of dangerous roads in the transportation lanes and working faces should be strictly checked for the signs of floods, and strict precautions should be taken to ensure production safety. On the other hand, the relevant departments at the county level, especially the heads of the coal bureaus and the coal-producing township people's governments should strengthen the daily safety inspection of coal mines, and check whether the mining operation procedures of the enterprises are reasonable, whether the ventilation facilities are perfect, and the underground site management personnel. Whether it is in place, whether the special operations personnel are matched, whether the various rules and regulations are established and improved, whether the safety production plan is formulated, whether the underground mining layout is reasonable, the problems are found to be corrected in time, and the plans for special hidden dangers are formulated to ensure hidden dangers. The rectification is timely, thus promoting the improvement of the safe production level of coal mines.
5. Focus on the key points, solve the difficulties, and comprehensively prevent production safety accidents.
At present, the focus of casualty accidents on coal mine safety production in our county is the roof and ventilation gas, but the difficulties in the work include the management of floods. Therefore, how to prevent the above three aspects of casualties is the top priority of our next step.
In the management of the roof, first, it is necessary to urge the enterprise to match the full-time top board administrator, to clarify its specific job responsibilities, working hours, work scope, strengthen the patrol inspection in the segmentation, and find out the problems in time; second, the operation of the enterprise Workers must follow the operating procedures, do the help of the top, support in place, line up in a row, fill must be fully connected, eliminate the empty top of the work surface, risky operations, technical personnel must be on-site command when handling dangerous rock The scientific plan measures can be carried out to prevent roof accidents. Third, the mine manager in charge of the underground coal mine must conduct regular spot checks on the work of the full-time top members and the support of the workers, and timely solve the problems in the roof work. Various problems; Fourth, coal mining enterprises should gradually implement the support materials of “taking steel to replace wood” to ensure that the support is in place.
In the management of ventilation gas, first, the enterprise must follow the 12-character policy of “first pumping, mining, monitoring and monitoring, and wind production”, comprehensively formulate the company's gas management plan, and strictly operate according to the plan; High gas mines must be equipped with gas monitoring systems. The scope, location and time of monitoring must be carried out according to the regulations, and special personnel are responsible; thirdly, the management of ventilation facilities is strengthened, and no wind and breeze operations are allowed underground, especially for the operation of taro. Ventilation management to prevent the sudden accumulation of gas; Fourth, enterprises must be equipped with gas inspectors and gas inspection equipment, and strengthen gas detection in strict accordance with the regulations, truly "one class three inspections", "one gun three inspections", resolute Eliminate the occurrence of gas accidents; Fifth, it is necessary to strengthen the management of underground electrical equipment, and prohibit underground mine electrical equipment from exploding; sixth, strictly follow the work of gas inspectors in the underground drilling operations to prevent gas accidents during the tunneling process.
In the management of floods, coal mining enterprises must adhere to the principle of “doubt must explore, first explore and then excavate”, and formulate flood control programs, especially mines with water threats, must carry out geological conditions on the goaf and aquifer. A comprehensive understanding to develop scientific exploration and release measures and programs. The underground water exploration and discharge work must be carried out according to the plan, and it is clear that the person is responsible. In the flood period, it is necessary to strengthen the management of the up and down duty of the well to prevent the threat of flooding to the mine.
The safety production responsibility of coal mines in our county is very important. We can only take the tough measures in accordance with the relevant laws, regulations and rules for coal mine safety production, work hard, and implement them in order to ensure the completion of the objectives and tasks of the provinces and municipalities.
