Investigation and elimination of hidden dangers in coal mine safety production accidents

First, how is the production accident hidden danger?

From the summary, summary and analysis of the types of coal mine production accidents and the nature of accidents in the province of Heilongjiang Province from 1994 to 2004, the following are some of the following factors: : that is, production personnel, machinery and equipment, natural environment.

1. Production workers are the mainstay of production activities. Due to differences in cultural level, professional quality, safety production concept, technical level and psychological quality, the safety development of coal mining enterprises is affected in actual production, and the quality of employees is high. It is possible to reduce the occurrence of accidents in actual production and vice versa. However, the actual coal mine production staff is highly mobile, the cultural level is low, the safety training time is short, and the legal and regulatory concepts are poor. The employees of the current coal mine production enterprises fail to achieve the principle of “special management and group management”. Produce everyone's management, pay attention to each other, supervise and stop the three violations and eliminate the hidden dangers of accidents. Everyone is responsible for the modern coal mine production management requirements. From the above analysis, it is found that coal mining enterprises must pay attention to the determinants of employees in safety production. It is also an active source of hidden dangers of accidents. The accidents caused by human factors cause the highest accident rate and the most harmful, which is the most active factor in accidents.

2. Mechanical equipment is the development direction of modern coal mining enterprises to improve production efficiency and reduce labor intensity. At present, the development of coal mining machinery and equipment is to improve the degree of mechanization, and is widely used in high-power, high-performance equipment. The accidents caused by mechanical equipment do not cause accidents themselves. The reason why accidents can be caused is that people do not fully understand the performance of the machine, and they fail to meet the requirements in operation and maintenance due to the factors of the machinery itself. Hidden dangers are generally manifested in years of disrepair, sick work, overload operation and erosion by downhole wet factors.

3, natural environmental factors due to the complex and variable working environment, mainly in the gas, coal dust, water, fire, roof and other natural disasters caused by accidents. The hidden dangers of such accidents are divided into long-term accidents and short-term accidents. The main hidden dangers of long-term accidents include: water disaster, gas explosion, coal dust explosion, natural fire tendency of coal, gas emission, roof pressure and so on. The short-term accidents are mainly caused by changes in geological structure, sudden abnormal changes in gas, coal dust and water inrush. In the long-term accident hazard of environmental factors, in the production process, effective prevention methods have been found. In addition to strengthening and strengthening management, a lot of basic work has been done in mining design and equipment configuration to ensure long-term accidents. Cause an accident. In addition, the accidents caused by short-term accidents are caused by the suddenness of such accidents. The cause of the accidents is: in the production process, the short-term accidents are encountered, and the on-site operators do not know the hidden dangers. High processing is not timely, the ability to respond is poor, and preventive measures cannot be taken in time to cause an accident.

Second, the investigation and elimination of hidden dangers

1. The key to troubleshooting and eliminating accidents is to detect hidden dangers in time and timely investigate and handle hidden dangers. This is the most effective way to prevent accidents. According to the specific conditions of production, a complete set of investigation system for accident hidden dangers can be established, which can effectively control the occurrence of accidents, especially the occurrence of major accidents.

2. The key to the investigation of hidden dangers in the investigation of hidden dangers of accidents is to grasp the site management. The principles for the investigation of accidents at the job site are: (1) unsafe and not productive; (2) the accidents are not completely disposed of and not produced; (3) safety measures are not implemented and not produced; (4) during production In the event of an accident, it is necessary to stop the operation immediately and carry out rectification of the hidden danger of the accident; (5) The hidden danger of the accident at the time of delivery is not completely handled, and must be clarified to the next class.

The key person to carry out this work is to follow the team captain. The professional knowledge is more or less, and the sense of responsibility is strong and weak, which directly affects the discovery, investigation and prevention of hidden dangers on the spot. Therefore, the key to grasping the hidden dangers of accidents is to grasp the safety management of the team leader and improve the safety quality of the team leader.

3. Hidden accidents of major accidents The hidden dangers of major accidents have long-term nature. Once an accident is caused, the harm is extremely great. Therefore, the principle of investigation of hidden dangers of major accidents has its particularity: First, effective and targeted preventive measures should be taken in time to control the accidents. The strength of the site manager's sense of responsibility and the level of safety technology he or she possesses determine whether the hazards of major accidents are harmful. The key technology to improve the safety level of site safety managers is timely to prevent major accidents, to prevent its harm is the investigation of major accidents to be fast, so that funds, materials, equipment, technical measures are in place, do not be afraid to spend money Don't be afraid of time and effort. Don't be lucky. Don't be eager for quick success.

Third, how to eliminate hidden dangers

Safety is the eternal theme of coal mining enterprises, and quality is the fundamental guarantee for achieving safe production. Therefore, coal mine safety production must be realized through quality standardization construction. The fundamental of quality standardization construction is to standardize individual work behaviors by improving the safety and technical quality of employees. Standardization of behavior requires that the behavior of practitioners be consistent with the operational standards and safety requirements of each job and each process. Only standardized individual behaviors can guarantee the standardization of individual behavioral outcomes, each individual behavior is standardized, and our entire work is standardized. So how can we achieve the standardization of behavior? The key is to continuously improve and enhance the safety awareness technical skills of all employees through various forms, multiple channels and safety culture. Due to the uneven quality of all aspects of the practitioners, Safety management methods are also very different, but one must persevere, that is, always keep parallel into a behavioral habit. This is not a one-off event, which requires the joint efforts of all the cadres and staff of the coal mine. The hidden dangers caused by accidents are the most active. Eliminating the hidden dangers of accidents must first grasp the key to human beings, adhere to the people-oriented principle, continuously strengthen the safety quality education of operators and managers, enhance people's safety responsibility, and implement responsibility system at all levels. Extensively learn and utilize new technologies and new equipment, so that everyone can deeply understand the hidden dangers of accidents and handle the hidden dangers of accidents. It is possible to achieve the purpose of eliminating accidents in the production process.
