Su Tao Kailuan Group Inner Mongolia Investment Company Zhungeerqi Yunfei Mining Co., Ltd. Erdos 010308, Inner Mongolia is simple. However, once the electrical equipment fails and cannot be maintained in a normal state, its protection and management are difficult to carry out, and it has a certain degree of complexity. The content of this paper mainly focuses on the development of power supply safety. Through the exploration of the key technologies of coal mine electrical equipment safety performance, it puts forward practical suggestions for power supply in coal mines. China's coal mine electrical equipment management overview China is a coal reserve country, the rational development of coal resources not only meets the energy needs of industrial development, but also greatly promotes the rapid development of China's economy. At present, the construction scale of domestic coal mine projects is continuously expanding. The supervision mechanism for electrical facilities is gradually applied to engineering construction. However, due to the late start of electrical equipment management in China, the management mechanisms and means are not yet mature, which directly leads to the management of electrical equipment. The separation between the links has slowed down the construction and development of coal mine projects. The imperfect management mechanism has also led to an increase in the construction energy consumption of coal mine projects, and the construction construction risks have also risen sharply. Various problems in the construction of coal mine projects indicate that the management of electrical equipment in the construction of coal mines in China should be guided by the actual construction of coal projects in China, and combine the project management theory with the actual construction of coal mines to achieve coal mine engineering. Scientific design and effective management. In the current stage of coal mine construction in China, due to the imperfect management mechanism of electrical equipment, the feasibility of the construction of various projects in the project needs to be improved, and the problems in the management details of the project management are all given to the management of coal mine electrical equipment in China. The practical application of the system presents challenges. Analysis of the safety factors affecting coal mine electrical equipment In the historical development of society, coal mine electrical facilities play an important role, but occasionally there will be coal mine electrical safety accidents, which to some extent remind people to guard against electricity safety when using electricity. Hidden dangers. Coal mining enterprises should also strengthen the prevention and maintenance of the safety of coal mine electrical facilities in the power supply to ensure the maximum degree of safety of coal mine electrical equipment. By analyzing the factors affecting the safety of coal mine electrical equipment, people can understand the real causes of coal mine electrical safety incidents, and at the same time alert relevant workers to strengthen the safety and system maintenance of electrical supply. 2.1 Analysis of facility wiring problems in coal mines The line problems are electrical safety problems, which are extremely common in the entire coal mine electrical implementation. However, considering the power transmission of the connection system of the power supply system, the power supply line should be used as the reference. The scope of influence is very wide In the entire power supply and practical applications, the transmission efficiency of electricity will have a direct impact on the circulation of the line. In addition, due to the certain correlation between the lines, the difficulty of line maintenance is also increased, and the line problem cannot be ascertained. Therefore, during the operation of the entire power system, the line is the most direct factor affecting the operation of the power supply system. Must be given enough attention. 2.2 Coal mine electrical equipment system problems System vulnerabilities in coal mine electrical equipment systems will also seriously affect the safety of coal mine electrical equipment. In order to effectively ensure the power supply of industrial construction and people's lives, the power plant will improve the power system, such as increasing the output of the power system and ensuring the normal supply of electricity. However, when power plants are improving their power systems, they are more likely to suffer from system vulnerabilities due to technical constraints and implementation errors. The emergence of such loopholes will cause power loss to some extent, if not handled in time. It will directly restrict the production and use of electricity, which will cause industrial electricity to be used, which will affect the smooth production of coal enterprises. 2.3 Supply system The development of the overloaded power supply society and the improvement of people's living standards have increased the requirements for the power supply efficiency of power supply companies. In order to ensure the normal power supply of the society, the power supply system is usually in overload operation, which increases the safety hazard of the power supply facilities to a certain extent. Due to the long-term overloaded working conditions, the probability of safety hazards in the power supply facilities is also Increasingly large, once the power supply facility has a power supply accident, then the normal work of the electricity company will be seriously affected, of course, coal enterprises are no exception. Technical exploration for maintaining the safety performance of coal mine electrical equipment 3.1 Power system troubleshooting and regular maintenance In the long-term operation, the power system will be affected by weather or system operation to produce different degrees of failure. The long-term accumulation of faults will cause the operation of the power system. Seriously affected, it is necessary to conduct regular safety hazard investigations on the power system to ensure the normal operation of the power system. In-depth study of system accidents through regular inspections of the power system. Considering that different factors in the power system will have different effects on the operation of the power system, when detecting the safety of the power system, the inspection strength should be increased to ensure that the system can achieve maximum repair, thereby effectively maintaining the operation of the power system. . 3.2 Strengthening the technology of relevant staff In the electrical system of coal enterprises, the operational skills of the staff are an important part of the management of coal mine electrical equipment. Therefore, it is necessary to enhance the technical ability of the staff and strengthen the management of the staff. At the same time, the execution ability of the staff in the coal mine will have a great impact on the work efficiency, which not only can effectively improve the operating efficiency of the electrical system, but also effectively prevent the staff's mistakes. In addition, the effective management of the staff can be strengthened, the team awareness between the personnel can be established, and the cohesiveness of the staff can be strengthened to jointly maintain the safe operation of the electrical system. 3.3 Realization of power supply automation With the continuous advancement of science and technology, the automation of the system has developed into a mainstream society. In order to reduce system accidents caused by staff errors in the electrical system of coal enterprises, automated electrical system construction provides an effective solution. By establishing an automatic operation mode in the electrical system, the electrical system can be automatically operated according to the settings, on the one hand, the working efficiency of the electrical system can be maximized, and on the other hand, the human safety hazard can be ensured. By establishing an automated electrical system, the main work of the staff turns to the supervision and control of the system, thus ensuring the safe operation of the automation system. In the construction of automated electrical systems, attention should also be paid to the details of the system and monitoring, while strengthening the construction of safety facilities for electrical systems. Because the automated electrical system can save manpower to a certain extent, and the manpower saving also reduces the difficulty of controlling the details of the operation of the electrical system, strengthening the detailed supervision and control of the automation of the electrical system can effectively avoid system accidents and thus realize the electrical system. Security. 3.4 Establishing perfect electric shock and its protective measures Electric shock is the most common safety hazard in coal mine power supply. There are two main types of electric shock, namely single-phase electric shock and two-way electric shock. The degree of personal injury often differs depending on the electric shock mode. The electric shock faults with different degrees will cause personal safety hazards to some extent, so strengthen The timely treatment of electric shock faults is an important measure to ensure that faults can be solved in the first time. In the power supply of coal mines, there are many preventive measures for electric shock hazards, such as ensuring the stability of voltage safety. At the same time, when using voltage, system testing of insulation devices such as energized facilities should be carried out first, and circuit problems should be effectively dealt with in time. In addition, the handling of insulation interfaces such as cable joints should be increased to ensure its sealing. As long as the leakage phenomenon is found, it is necessary to check and conduct isolation at the first time to reduce the occurrence of electric shock accidents. Conclusion The development of coal mining enterprises will help promote social and economic construction and improve people's quality of life to a certain extent. On the one hand, we must affirm the outstanding contribution of the coal mine system to social development. On the other hand, we should also increase the prevention of safety hazards in the coal mine electrical system, and continue to learn more efficient while strengthening the safety awareness of coal mine electrical facilities. The method of dealing with the failure of coal mine electrical facilities to ensure the normal supply and safe use of electricity. In addition, it is necessary to increase the safety supervision of coal mine enterprises' power supply, such as regularly detecting power facilities and continuously implementing safe power supply, so as to ensure the safety of production.
