摘　　要：根据贵州桐梓县清和煤矿煤层样品化验测试结合煤炭勘查数据对瓦斯地质特征进行了分析。结果表明:区内各煤层均属富甲烷煤层;瓦斯成分及含量平面上自矿区北部向南部呈递增的变化趋势,垂向上随煤层埋藏深度增大而增加;煤层气资源量为0.96×10^(8)m^(3);该矿井为瓦斯突出矿井。According to the coal seam sample test of Qinghe Coal Mine in Tongzi County of Guizhou Province,combined with the coal exploration data,the gas geological characteristics are analyzed.The results show that all the coal seams in the area are rich in methane,and the gas composition and content are increasing from the north to the south.Vertically,it increases with the burial depth of coal seam.The CBM resource is 0.96×10^(8)m^(3),and the mine is a gas outburst mine.
