摘要
本文以资料对比的方法讨论了芦岭煤矿各煤层瓦斯涌出的差异。分析了8号煤层瓦斯涌出量,认为应对8号煤预抽瓦斯。这种情况下,煤层吸附瓦斯形成一种有用的资源。
Discussion is made through comparison of data available about differences is gas gushes between coal seams in Luling Coal Mine. Investigations are conducted into the primary factors responsible for great amounts of gas of gas gushing out of Seam No. 8 . In order to reduce gas gush amounts in this seam, pre-drainage of gas should be practised, in the course of which attention should be paid to Seam-absorbed gas, a useful resource
