摘要
分析了矿井的水文地质条件,对主要充水含水层进行了分析、划分和对比;对断层构造的导水性、富水性进行了分析。论述了水文地质边界条件。采用大井法和比拟法预测了矿井涌水量,对计算结果进行了评价。对二1煤层充水因素进行了分析,指出奥陶系白云质灰岩岩溶裂隙水为本区二1煤层充水的重要因素之一,并对断裂构造、地表水体、封闭钻孔对二1煤层开采的影响进行了分析。
The mine hydro geology conditions is analyzed.Mainly water-filled aquifer beds are analyzed,divided and contrasted.Water flowing and water abundance are analyzed.The hydro geological boundary conditions are discussed.With big well method and analogy method to predict Water Inflow Quantity,the calculation result is evaluated.Analyzing of二1 coal bed minefield water filling factors,pointing out that Ordovician diplomatic limestone karsts crevice-water is one of the most important factors.Besides,influence of rift structure,surface water and closing bore to二1 coal bed coal seam mining are analyzed.
