铁炭窑沟矿井田水文地质条件探讨

Probe into Hydro-geological Condition of the Minefield of Tietanyaogou Coalmine

通过对铁炭窑沟矿井田水文地质的探讨,得出该井田内主要含水层包括5组,主要隔水层有两组,地下水的补给、径流及排泄条件良好,矿井水文地质为简单类型,奥灰水对矿井开采无影响,矿井充水因素为采空区积水,生产时要特别注意,矿井涌水量为100 m3/d左右,基本不影响矿井的正常生产。

Through probing into hydro-geological condition of the minefield of Tietanyaogou Coalmine, this paper draws the conclusions that the main water-bearing layers in the minefield include five groups, the main water-resisting layers have two groups, the groundwater＇s recharge, runoff and discharge conditions are good, the minefield＇s hydro- geological condition belongs to the simple type, the Ordovician limestone water has no effect on the mining of the minefield, in the production should pay special attention to the goaf water which is the mine water filling factor, the mine inflow is about 100 m3/d, basically has not effect on the normal production of minefield.
