Underground power supply in coal mines is one of the fundamental guarantees for coal mine safety production. The stability and reliability of the underground power supply system in coal mines are directly related to the normal operation of the mine and the safety of miners.
1、 Security management
Establish a sound power supply management system: The underground power supply management of coal mines must establish a sound system, including the management system of power supply equipment, operating procedures, safety inspection system, etc. These systems should clarify the responsibilities of managers and operators at all levels to ensure the standardized management and safe operation of the power supply system.
Strictly implement safety regulations: Power supply operations must be strictly carried out in accordance with relevant safety regulations, especially in equipment installation, debugging, operation, maintenance and other links, ensuring that every operation meets safety requirements and preventing accidents.
Regular safety inspections: Safety inspections of the power supply system should be carried out as part of daily management work and conducted regularly. The inspection includes the operation status of the equipment, the integrity of the cable lines, and the effectiveness of the grounding system. By conducting regular inspections, identifying and eliminating hidden dangers in a timely manner, we ensure the safety and reliability of the power supply system.
2、 Equipment maintenance
Regular maintenance: The maintenance of power supply equipment should be carried out according to the plan, including cleaning equipment, tightening wiring, inspecting insulation, testing protective devices, etc. Regular maintenance can prevent equipment aging and malfunctions, improve the service life and operational efficiency of the equipment.
Equipment updates and upgrades: For old equipment, timely updates and upgrades should be carried out, and new equipment with good technology and reliable performance should be adopted to improve the overall level of the power supply system. Especially in high-risk areas, priority should be given to using equipment with higher safety performance to ensure power supply safety.
Spare parts management: The spare parts of the power supply system should have sufficient reserves and establish a spare parts management system to ensure timely replacement in case of equipment failure, reduce power outage time caused by equipment failure, and ensure production continuity.
3、 Emergency response
Establish emergency plans: The underground power supply system of coal mines should establish a comprehensive emergency plan, specifying emergency response measures and processes in the event of sudden power supply failures or accidents. The emergency plan should include accident reporting, emergency response, fault handling, personnel evacuation, etc., to ensure quick and effective response in emergency situations.
Emergency drills: Regular emergency drills are conducted to simulate power supply failures or accidents, verify and improve emergency plans, improve the emergency response capabilities of power supply management and operators, ensure that they can respond calmly in emergencies, and minimize losses to a greater extent.
Emergency supplies preparation: Emergency supplies are the basic guarantee for emergency response. The power supply system should reserve sufficient emergency supplies, such as emergency power supplies, lighting equipment, repair tools, etc., to ensure that they can be quickly put into use in case of emergencies, and to ensure power supply restoration and safe evacuation.
4、 Personnel training
Technical training: Power supply management and operators should receive systematic technical training, master the principles, operating procedures, and maintenance knowledge of power supply equipment, ensure the correct operation and maintenance of equipment, and prevent and handle faults.
Safety training: Safety training is a key link in ensuring power supply safety. The training content should include safety operating procedures, safety protection knowledge, emergency response skills, etc. Through training, personnel's safety awareness and skills should be improved to prevent safety accidents caused by improper operation.
Certified on duty: Power supply management and operators must hold a certificate on duty, strictly implement the certification system, ensure that operators have received training and assessment, possess corresponding operational skills and safety knowledge, and ensure the safe operation of the power supply system.
5、 New Technology Applications
Intelligent monitoring system: Introducing an intelligent monitoring system to monitor and analyze power supply equipment in real-time, detect abnormal situations in a timely manner, and improve fault warning capabilities. Intelligent monitoring systems can achieve remote monitoring and management, improving the safety and reliability of power supply systems.
Automation control system: Adopting an automation control system to achieve automated operation and management of power supply equipment, improving the operational efficiency and safety of the power supply system. Automated control systems can reduce human operational errors and lower the risk of accidents.
Energy saving technology: Introducing energy-saving technology to improve the energy efficiency of power supply systems, reduce energy consumption and operating costs. Energy saving technologies include high-efficiency motors, energy-saving transformers, variable frequency speed regulation technology, etc. Through energy-saving transformation, green environmental protection and sustainable development of the power supply system can be achieved.
Underground power supply in coal mines is a key link in coal mine safety production, and it is necessary to implement safety management, equipment maintenance, emergency response, and personnel training. By establishing a sound power supply management system, regularly maintaining equipment, developing and practicing emergency plans, strengthening personnel training, and introducing new technologies, the safe and reliable operation of the power supply system can be effectively guaranteed, ensuring the safety of mine production and the life safety of miners.
