煤矿供电系统防雷接地技术优化

Optimization of lightning protection and grounding technology for coal mine power supply system

摘要

煤矿供电系统是煤矿生产的“生命线”，承担着为井下采掘、通风、排水等核心设备提供稳定电力的职责，其运行可靠性直接关系到生产安全、效率及人员人身安全。煤矿生产环境特殊，多数矿区地处开阔地带，井下空间密闭、潮湿多尘且存在易燃易爆气体，供电线路需跨越复杂地形，长期承受恶劣自然环境侵蚀。雷电作为强烈自然放电现象，会通过直击、感应等方式侵入供电系统，损坏电气设备、引发供电中断，严重时还会引燃瓦斯煤尘，诱发重特大安全事故。

Abstract

The power supply system in coal mines serves as the “lifeline” of mining operations, providing stable electricity for critical underground equipment such as mining, ventilation, and drainage. Its operational reliability directly impacts production safety, efficiency, and personnel safety. Coal mining environments are inherently challenging, with most mining areas located in open terrain. Underground spaces are confined, damp, and dusty, often containing flammable and explosive gases. Power lines must traverse complex terrains and endure prolonged exposure to harsh natural conditions. Lightning, a powerful natural discharge phenomenon, can invade the power system through direct strikes or induced currents, damaging electrical equipment and causing power outages. In severe cases, it may ignite gas or coal dust, potentially triggering major safety accidents.
