小康煤矿S2S2综放面水体下开采安全可行性研究

根据小康煤矿井田及南二采区南二工作面煤层赋存、地质构造、水文地质、采煤方法等采矿地质条件,结合小康煤矿以往防治水工作经验,对S2S2工作面开采矿井充水因素、覆岩导水裂缝带发育高度、断层与钻孔的导水性等进行了分析与研究,认为S2S2综放工作面能够在地表塌陷坑积水下实现安全开采。

Safe Feasibility Study on Mining Under Water System at S2S2 Fully Mechanized and Caving Face of Xiaokang Coal Mine

According to the mining geology conditions such as the coal seal existing,geologic structure,hgdrogeology,mining methods at S2S2 face of Xiaokang Coal Mine,in combination with the experience in prevention and cure of water in Xiaokang Coal Mine in the past,the analysis and study on the mine flush factors of S2S2 face, the growth height of the cover rock guide crack field,the guide characteristics of faults and drilling holes are in progress.It's possible for S2S2 fully mechanized and caving face to realize safe mining under the earth's surface collapse pits water-logged ground.
