摘要
章村矿31采区北部存在丰里向斜构造,采区西部断层较为发育,当开采最西部2号煤3100A工作面时,受断层及向斜构造影响,工作面排水系统较复杂。根据此区域地质构成赋存情况,在近距离煤层下层煤已有巷道施工泄水孔,疏放上层煤采空区积水,不仅解决了上层煤回采工作面仰采排水系统复杂、受水患影响大的问题,也提前做到了下层煤巷道掘进时对上部采空区积水的提前疏放工作。
There is a Fengli syncline structure in the northern part of the 31 mining area of Zhangcun Mine,and faults are relatively developed in the western part of the mining area.When mining the 3100A working face of the westernmost No.2 coal seam,the drainage system of the working face is more complex due to the influence of faults and synclines.Based on the geological composition and occurrence of this area,drainage holes have been constructed in the lower coal seam of the close distance coal seam to drain the water in the upper coal goaf.This not only solves the problem of the complex drainage system in the upper coal mining face and is greatly affected by water hazards,but also achieves the early drainage of the water in the upper goaf during the excavation of the lower coal roadway,which has great promotion value.
