摘　　要：通过调查水文地质条件和补充勘探,研究沙坪煤业充水因素并预测涌水量。结果显示:主要充水水源包括大气降水及地表水、第四系松散岩类孔隙水、奥陶系中统上马家沟组碳酸盐岩类岩溶裂隙水等;充水通道主要为断裂及破碎带、顶板采动破坏带和底板采动破坏带、废弃老窑和封闭不良钻孔等。采用富水系数比拟法预测全矿井正常涌水量约为126.7 m^(3)/h,最大涌水量约为242.6 m^(3)/h,为矿井水害防治提供了依据。Through hydrogeologic prospecting and supplementary exploration,water filling factors and water inflow prediction of Shaping Coal Industry Co.,Ltd.were studied.The results showed that the main water sources included atmospheric precipitation and surface water,pore water of Quaternary loose rocks,carbonate fissure water of Upper Majiagou Formation of Ordovician Middle Series,etc;the water filling channels were mainly fracture and crushing zone,mining failure zones of roof and floor,abandoned old goaf and poorly sealed borehole.By using the water-rich coefficient analogy method,it was predicted that the normal water inflow of the whole mine was about 126.7 m^(3)/h,and the maximum water inflow was about 242.6 m^(3)/h,which provided a basis for the prevention and control of mine water damage.
