厚松散含水层条件下，开采浅埋煤层易产生突水溃沙地质灾害，为了减轻煤层顶板压力，在神府矿区首采高产高效工作面采用了采前疏降水方法，其总结出的“井上井下、双管强排、抽泄结合”的地下水疏降方法，经实践证明是经济合理、行之有效的。 In the condition of thick loose aquifer, the mining of shallow coal seam is easy to produce the geological disasters of water inrush and sandblasting. In order to reduce the pressure of coal seam roof, the method of pre-drainage is adopted in the first high-productivity and high-efficiency working face of Shenfu mining area, Downhole, double-row strong row, pumping combination of "groundwater drainage methods, proved to be economical and reasonable, effective.
