摘要
依据大量勘探资料分析某矿井的充水因素,研究得出4~#煤层的直接充水水源是山西组裂隙含水层与二叠系孙家沟组、石盒子组裂隙含水层,古近系及基岩风化带孔隙裂隙含水层为间接充水水源,矿井主要充水通道为断层和煤层开采形成的导水裂隙带。
The water filling factors for the mine are analyzed based on a large amount of exploration data. The research indicates that the direct water filling source for No.4 coal seam is the fissured aquifer of Shanxi group, the permian system of Sunjiagou group and Shihezi group. The fissured aquifer of paleogene and weathered zone of basement pore is the indirect water filling source. The main water filling channel of the mine is the water-flowing fractured zone formed fault and coal mining.
