Application of high-density electrical method in identification and prevention and control of Quaternary loose aquifer water
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.
