Abstract: Due to the particularity of thetechnology, the gas drainage pump station in coal mines, with major hidden danger, may cause severe accident when struck by lightning. Based on the reality of the gas drainage pump station in Yadian coal mine, this paper determines the lightning protection level of buildings according to relevant design specifications,fixesthe scope of lightning protection with the “rolling ball method”, and carries out safety analysis of various lightning protection forms. It is found that when single / double lightning rod and single lightning wire are used as lightning arresters, they can not meet the relevant requirements of the first type of lightning protection building; preference should be given to multiple equal height lightning rods as lightning arresters; when multiple lightning rods cannot meet the requirements of lightning protection, two lightning wires should be used for protection. This paper can serve as reference for the lightning protection design of gas drainage pump stations.
