Through the development of low rank coal mining area roadway excavation process caused by H_2S gas abnormal geological features, rock properties, groundwater distribution, the metamorphic degree of coal, coal sulfur content such as five aspects analysis, concluded that H_2S in the mine for the formation of the genetic type of BSR. And put forward effective prevention and control measures for H_2S abnormal area, which has a certain guiding role for mine safety production. No.1 coal seam in the west of the mining area and the surrounding area of No.4 coal seam high sulfur area, should attach great importance to the H_2S anomaly.
