摘　　要：露天煤矿安全生产与地下水赋存有密切的联系,为准确探测浅层砂层、含水层厚度,查明第四系松散含水层水的分布规律,有效控制水对安全生产影响,以扎哈淖尔露天煤矿为研究对象,运用高密度电法物探技术,结合软件反演计算,绘制了反演电阻率断面图,识别了潜水层和隔水层分界线及砂层含水情况,精准建立疏干井降低地下水位,控制渗流涌水。研究结果表明:高密度电法细化了砂层和含水砂层富水程度,有效提升了疏干井疏干效果。The safe production of open-pit coal mine is closely related to the occurrence of underground water.In order to accurately detect the thickness of the shallow sand layer and aquifer,find out the distribution law of the Quaternary loose aquifer water,and effectively control the impact of water on safe production,the inverse resistivity section map is drawn by taking Zhahanao’er Open-pit Coal Mine as the research object,using high-density electrical geophysical prospecting technology and combining with software inversion calculation.The article identified the boundary between phreatic layer and aquiclude layer and the water content of sand layer,accurately established drainage wells to reduce the groundwater level and control seepage and water inflow.The results show that the high-density electrical method can refine the water content of the sand layer and the water-bearing sand layer,and effectively improve the drainage effect of drainage well.
