本文通过对山西省2000年-2012年发生的59起煤矿雷电灾害的统计分析，发现微电子设备、配电设备等是煤矿最容易遭受雷击的设备。文中给出了煤矿生产各个系统容易遭受的雷电灾害的类型，易受雷击的部位、原因，讨论了山西省煤矿雷电灾害的地区分布与闪电密度及煤矿数量的关系，并以雄山煤矿为例分析了煤矿雷击的典型案例。
Baesd on statistical analysis of 59 national lightning disasters cases of coal mine from 2000 to 2011, it was found that microelectronic devices, power equipment are vulnerable to coal mine lightning. There were 25cases microelectronics devices; 13cases distribution equipment lightning disasters. Further analysis found that the monitoring equipment and transmission Line were the hardest hits. The strikes were given, discuss the geographical distribution of Coal Mine L sys igh terns of mine which vulnerable to lightning tning disasters in Shanxi and the lightning flash density and the relationship between the numbers of lightning disasters. Hill coal mine as an example typical case of lightning disasters were discuss
