The working environment underground in coal mines is complex, and the stability and safety of the power supply system are crucial. In order to ensure the safety of mine production, the following is a practical guide for adjusting the underground power supply system in coal mines, which helps mining enterprises improve their power supply management level and reduce safety risks.

The underground power supply system in coal mines is an important guarantee for mine production, but due to the special underground environment, there are many safety hazards. Common problems include aging power supply lines, high equipment failure rates, and inadequate protection measures. These issues may lead to interruptions in mine production and even trigger safety accidents.

Adjustment measures for power supply system

Improve power supply design: Based on the production needs of the mine, design the power supply system reasonably, ensure that the power supply lines and equipment layout are reasonable, and meet the electricity demand during the peak period of mine production. At the same time, reserve a certain capacity of backup power supply to cope with unexpected situations.

Update power supply equipment: Regularly inspect power supply equipment, eliminate aging and damaged equipment, and timely update high-performance and low failure rate power supply equipment. Select equipment with explosion-proof, moisture-proof, anti-interference and other functions to improve the reliability of the underground power supply system.

Optimize power supply lines: Optimize power supply lines to shorten their length and reduce line losses. By using cable trays, bridge frames and other facilities, we ensure that cable laying is standardized and neat, and reduce faults caused by line problems.

Strengthening protection measures: Equip the power supply system with overload, short circuit, leakage and other protection devices to ensure that the power can be quickly cut off in the event of a fault and prevent the accident from expanding. Regularly inspect the protective devices to ensure their normal operation.

Improving personnel quality: Strengthen the training of mine power supply system operators to enhance their professional skills and safety awareness. Ensure that operators are familiar with the working principles, operating procedures, and emergency plans of the power supply system.

Establish a monitoring system: Utilize modern information technology to establish a monitoring platform for the mine power supply system, which can monitor the operation status of power supply equipment, power parameters, and other data in real time. Discover abnormal situations and handle them promptly.

The adjustment of mine power supply system is an important measure to ensure mine safety. By improving power supply design, updating equipment, optimizing lines, and strengthening protection measures, the stability of the power supply system can be effectively improved and safety risks can be reduced. Mining enterprises should strengthen the management of the power supply system based on their actual situation, and provide strong support for the safety production of mines.
