　　1. Characteristics of Coal Mine Equipment Maintenance
　　(1) Characteristics of Coal Production
　　1. Eighty percent of the work is carried out in underground tunnels.
　　2. This is a very dangerous industry, often affected by water, fire, gas dust, and roof conditions.
　　3. The working space is relatively small, and both the natural and working environments are not very favorable.
　　4. Geological structures have serious variability issues, and the mechanization and automation of coal mine electromechanical equipment are limited by economic and geological factors.
　　5. The operation of electromechanical equipment requires precise control according to instructions, and management of electromechanical equipment must be strengthened.
　　(2) Characteristics of Coal Mine Equipment Failures
　　Coal mine electromechanical equipment has explosion-proof features, but it is not easy to disassemble and assemble, and certain faults may occur. Due to the variety and large quantity of such equipment models, many domestically produced devices fail to meet stable quality and fault-free requirements. Common faults are often random and some are undetectable. In the electromechanical production process, all systems are interconnected; one problem may cause another. These sudden and multi-mode faults can cause huge losses.
　　(3) Characteristics of Coal Equipment Usage
　　1. Due to limited space for mechanical installation and use underground, maintenance and upkeep of machinery are very difficult to operate.
　　2. Mine equipment has high requirements for explosion-proof functions, with safety as the main focus.
　　3. Mine electromechanical equipment operates continuously and cannot be stopped; even maintenance must be completed in the shortest time possible.
　　2. The Status and Role of Coal Mine Electromechanical Equipment Management
　　Electromechanical equipment in mines plays a leading role in coal mining production. Management of electromechanical equipment should start from the most basic aspects, fully implementing management to ensure equipment operates safely, reliably, and efficiently. On the basis of ensuring the safety of mine electromechanical equipment, leverage principles should be applied to elevate management, establish effective and reasonable management regulations, and focus on management work.
　　(1) Electromechanical Equipment Management is an Important Material Basis and Technical Guarantee for Safe Production in Coal Mining Enterprises
　　The core of enterprise safety lies in equipment management. The quality of equipment management affects the normal operation and development of the enterprise and serves as its main technical guarantee and material foundation. This is mainly reflected in the level of productivity, management differences, and industrial technology improvements. If ventilation, power supply, or drainage systems in coal mine equipment fail, mine safety will be affected. The normal use of all parts of coal mine equipment is closely related to coal production and worker safety.
　　(2) Electromechanical Equipment Management is the Basic Guarantee for Achieving High and Stable Production
　　Many mines in China have been constructed for decades but have only been in use for a few years. Some mines are continuously deepening, and some special coal seams are gradually appearing. Many high-tech and safe mine devices are being introduced, installed, and used. Currently, five-sixths of coal mine operators are not professional electromechanical personnel. During equipment operation, the lack of professionalism and operational errors by maintenance and operators will impact production.
　　(3) Electromechanical Equipment Management is Key to Achieving Energy Conservation, Emission Reduction, and Environmental Protection in Coal Mining Enterprises
　　A large portion of asset protection in Chinese coal mines involves electromechanical equipment and facility protection. A significant amount of funds is spent on equipment and facilities, accounting for two-fifths of costs. This shows that reasonable management and use of electromechanical equipment to reduce equipment loss is the foundation for enterprises to gain maximum benefits and is also conducive to long-term development.
　　3. Management and Maintenance of Coal Mine Electromechanical Equipment
　　(1) Improve Electromechanical Professional Management Systems and Implement Safe and Effective Management Systems
　　This can ensure the safe operation of equipment and improve the enterprise's safety index, thereby guaranteeing smooth production.
　　There are four main aspects:
　　(1) Formulate appropriate and reasonable management models to make various systems more comprehensive.
　　(2) Communicate and implement all aspects of safe production, enforce production and post responsibility systems according to work regulations, hold accountable for accidents, and ensure each position has specific personnel responsible.
　　(3) Coordinate production and electromechanical work, establish certain rules and regulations, strictly manage according to these rules, grant the electromechanical department certain operational rights, treat it as the true electromechanical management department of the entire mine, enabling electromechanical personnel to play a role and perform management well.
　　(4) Make the electromechanical management team more organized, eliminate the phenomenon of one person holding multiple posts, reasonably allocate personnel work, which is conducive to work development and improvement.
　　(2) Increase Equipment Investment and Optimize Electromechanical Equipment Level
　　To ensure safe equipment operation while improving work efficiency, advanced, scientific, and reliable equipment must be used as the foundational condition. Adequate funding should be secured to ensure equipment is up-to-date. Additionally, technology guarantees and sensitivity and reliability standards must be met. Efforts should be intensified to use advanced technology and new equipment to replace past production modes. Machines with incomplete protection measures should be repaired and protected according to regulations or directly eliminated.
　　(3) Strengthen Safety Education and Training, Emphasize Management
　　Coal mine safety is a critical aspect. Not only should managers coordinate safety work from a high level, but employees and inspectors should also recognize the importance of the issue. The personal safety of coal mine workers and national property safety are issues that cannot be ignored. Every effort should be made to ensure coal mine safety, establish sound systems, and quickly build a high-quality professional electromechanical talent team in an appropriate educational environment to ensure the improvement and sustainable development of electromechanical work.
　　As a leader in mine electromechanical management, one should adopt the strategy of "going out and inviting in" to promote the development of electromechanical management, operate step by step, learn scientific management methods from other enterprises, recognize one's own shortcomings, and make improvements. First, it is necessary to understand the management theory of equipment maintenance, and also to understand the management methods of equipment and enterprises. Currently, coal mine electromechanical management is at the maintenance management level.
　　(4) Strengthen the training of electromechanical technical professionals.
　　From the current situation, what enterprises lack most are electromechanical technical talents. Changing this phenomenon must start from changing the training environment for talents and accelerating the growth of electromechanical technical personnel. However, what makes us happy is that through the training of electromechanical technical talents, our enterprise now has a group of electromechanical technical personnel with very strong working abilities. We give these talents a lot of encouragement and honors.
　　Of course, enterprises cannot only see the demonstration effect it produces while ignoring the practical problems in enterprise development, otherwise the corresponding demonstration purpose cannot be achieved. Therefore, it is necessary to fully supervise and assess such workers, so that the value created is proportional to the economic benefits obtained, thereby playing a leading role. Electromechanical technical personnel must be able to accurately judge the causes of accidents and make repairs in the shortest time, but this is not a goal that can be achieved in a short period. The multifaceted nature of electromechanical equipment makes it very complex, so electromechanical technical personnel must have a certain level of understanding and sufficient knowledge of the equipment. In terms of personal qualities, they must have the spirit of endurance and dedication to the enterprise.
　　In summary,
　　we can understand that the electromechanical system is very complex, and effective management helps ensure the safe production of the mine and improve economic benefits. Currently, the management of electromechanical equipment uses the economy as the main leverage method, taking the safety of mine production as the center.
　　Starting from the lowest level of work, do a good job in equipment management, eliminate various safety hazards of electromechanical equipment, and ensure its safety and reliability. This can win stronger economic and social benefits for the company. Prevention and control work in the mine should also be emphasized. In daily work, preventive measures must be well implemented and management must be strict, so that more benefits can ultimately be obtained.
