摘要
煤矿一般处于山岭地带,大气和地质情况均较复杂,其主要建筑物、天轮架、通风机以及供配电系统、信息化网络设备等易遭受雷电侵害。依据乌海地区气象和矿井的实际情况,针对煤矿防雷保护对象的研究,提出了防雷技术的改造设计方案。该方案通过实际应用,收到良好的效果,能防护99%的雷电灾害,目前乌海地区各矿都按照此方案进行整改。
Because the coal mine is located in mountainous areas, the atmosphere and the geological conditions are complicated. The main building, sheave frame, ventilator, power supply system and the information network equipment are vulnerable against the lightning accidents. According to the actual situation of atmosphere and coal mines in Wuhai area, proposes the renovation design scheme of lightning protection on account of the lightning protection objects. This scheme gains good effect by application and protect 99% lightning accidents. Nowadays, each coal mine in Wuhai area processes the renovation based on this scheme.
