摘要
针对吉克煤矿近距离突出可采煤层群的开采情况,根据其地质情况及煤层瓦斯基础参数情况,进行开采保护层的选择,并论证其可行性,对所选保护层与邻近层进行大面积瓦斯预抽方案设计,使矿井安全高效生产。
according to the mining conditions of closed distance outburst coal seams in Jike coal mine,the mining protective layer was selected and its feasibility was proofed based on geological conditions and coal seam gas basic parameters.The large acreage gas pre-pumping program for protective layer and adjacent layer was designed,which promoted the safe and efficient mine production.
