摘要
利民煤矿处于山岭空旷地带,大气和地理位置均较复杂,其主要建筑物,如副井的天轮架、风机,供配电系统和信息化网络设备等易遭受雷电侵害,对防雷设计工作要求较高.2010年该矿副井天轮架和信息显示屏均遭受过雷击,引起事故.针对利民煤矿的具体情况,提出了防雷改造方案,方案实施后运行至今,未出现过雷击事故,防雷效果良好.
Limin coal mine is in the mountains open area, atmosphere and geology conditions are complicated. The major buildings, sueh as head sheave frame of auxiliary shaft, fan and equipment of power supply, distribution system, information and network, are lightning infringement easily; therefore, design work of lightning protection is important. In 2010, the mine auxiliary shaft the head sheave frame and information display also have been attacked by lightning, and causing the accident. Running well after the implementation of the program has not appeared lightning accidents with good lightning effect.
