摘要
该煤矿位于贵州省兴仁县下山镇,文章通过对瓦斯样品的测试,矿区内各可采煤层空气干燥基瓦斯含量最大值为4.00～12.71 ml/g,空气干燥基CH4+C2H6含量最大值为1.17～3.32 ml/g;该矿井属于低瓦斯矿井,发生煤与瓦斯突出事故的可能性小。
The coal mine is located in Xiashan Town,Xingren County,Guizhou Province.Through the test of gas samples,the maximum gas content of air drying base gas content in each mining seam was 4.00~12.71 ml/g.The maximum CH4+C2H6 content of air drying base was 1.17~3.32 ml/g.This mine belongs to low gas mine,the possibility of coal and gas outburst accident is small.
