摘要
冯记沟煤矿产量30万t/a,但矿井最大涌水量达1 000m3/h。通过对该区水文地质条件和充水因素的分析,认为矿井直接充水水源是侏罗系层状裂隙孔隙水,间接充水水源是第四系孔隙水、老窿区积水和矿井排水。针对矿井充水水源和充水通道的发育状况,提出了几种防治水的方法建议。
The Fengjigou coalmine＇s capacity is 300,000t/a, while its maximum mine water inflow is 1,000m^3/h. After analyzed the hydrogeological condition and water filling factors in the area, considered that the Jurassic bedded fissure and pore water is the direct water filling source, the Quaternary pore water, gob water and mine drainage are indirect water filling sources. In allusion to mine water filling sources and channel developing situation put forward some water control suggestions.
