摘要
通过实测数据确定了旧街煤矿的瓦斯赋存规律,并分析了开采8号煤层时的瓦斯涌出规律,明确了瓦斯治理的重点。结果表明:旧街煤矿瓦斯含量具有随煤层埋深增加而增大的总体趋势,增长梯度为0.916m3/t/100m;邻近层和采空区瓦斯是矿井瓦斯治理的重点。
The methane occurrence law in Jiujie Mine is determined,its emission law is analyzed,the priorities in gas control in No.8 coal seam is defined by measured data.The result shows that the content of gas in Jiujie Mine was found to increase with burial depth,the gradient is 0.916m3/t/100m and the gas in near coal bed and mine goaf is the keystone of gas control.
