Model for Groundwater Searching with Drilling in Karst Area near Deep Valley
摘要
Abstract
Surface water rapidly infiltrates in karst area near deep river valley,and karst groundwater is deeply buried with concentrated runoff;therefore,water resources shortage near deep river valley is serious,which leads to the formation of arid areas.At the same time,in this area,influenced by groundwater discharge surface controlled by deep valleys,groundwater flow is mostly in quick pipe and fracture;storage space distribution and the connectivity of each other bring great difficulties to drill well for searching groundwater.The authors disco-vered that the underlying clastic rock,reverse fault and overlying clastic rock can cut off the relationship be-tween karst groundwater and deep valley surface water,which lead this area to be local rich water and become the favorable target area for water drilling.Based on the 3 types,with the successful examples,it is classified into 3 water drilling models:the underlying clastic rock water model,inverse water resistance model,and over-lying clastic rock water blocking model.These models will give some helps for water drilling in karst area near the deep valley.关键词
