摘要
司马煤矿为煤与瓦斯突出矿井,采煤工作面采用本煤层顺层钻孔抽放瓦斯,并进行埋管抽放采空区瓦斯,掘进工作面采用超前钻孔抽放瓦斯,取得了较好的安全、经济效益。
According to actual situation of the mine, gas drainage borehole and corresponding safety measures have been adopted in the mining surface construction process, which ensures safety production and improves coal mine safety benefits.
