摘要
Abstract
According to the coal seam gas sample data obtained from the previous geological exploration work of coal mine,the gas pa-rameters of each coal seam in the mining area were analyzed.Meanwhile,the gas occurrence rule of coal mine was studied from the anal-ysis of the geological structure,the degree of coalification,the thickness of coal seam,the depth of coal seam and the roof of coal seam.According to the data of coal seam gas content in drilling,the maximum gas content of the borehole was less than 4 m3/t.According to"Coal and Gas outburst risk area Prediction Method"and "Coal Mine Geological Work Regulations",it is concluded that the whole mining area is no outburst risk area and the mine gas type is simple type.关键词
