摘要
矿井直接充水水源为煤系地层裂隙孔隙水,开采初期揭露含水层后,矿井涌水量增加较大,主要以疏干漏斗范围内的贮存量为主,漏斗稳定后,矿井涌水量以地下水的侧向补给为主。粗粒含水层的富水性和导水性相对较好,以孔隙为主的渗入性通道是矿井充水的主要途径。
Coal-bearing strata fissure water is the direct water sources of coal mine, after ming the initial exposed aquifer, the qauntiy of mine water discharge, increases largely, the main storage capacity is the scope of the funnel, after the funnel is stable, the quantily of mine water discharge are mainly lateral groundwater recharge. The performanse of rich water and lead water of coarse-grained aquifer are relatively good, and permeability way with fissures is the main channel for filling water to coal mine.
