瓦斯抽采技术在西铭矿48411工作面的应用

Application on Gas Drainage and Extraction Technology in 48411 Mining Face of Ximing Coal Mine

针对西铭矿48411工作面瓦斯涌出量较高的现状,提出了在该面采用采空区裂隙带钻孔和本煤层钻孔混合抽采方案,并介绍了方案的实施应用过程。该技术的应用对高瓦斯矿井,特别是在有煤层自燃倾向性工作面的高瓦斯矿井具有较高的推广应用价值。

In connection with the present situation of higher gas emission quantity in 48411 mining face of Ximing coal mine, puts forward the drainage and extraction plan of using the goaf fissure zone drilling and this coal seam drilling mixing in this face, and introduces implementation and application process of the plan. Application of this technology to the high gaseous mine, specially has high promotion application value in the high gaseous mine of the mining face of having coal seam spontaneous combustion tendentious.
