摘要
断裂蓄水构造是河南省缺水山区成井最多的一类蓄水构造,寻找断裂蓄水构造是找水的主要方向.在分析断裂蓄水构造的分类和储水特征的基础上,提出遵循水文地质工作与综合物探技术密切结合的原则综合定井的找水方法,在水文地质工作选定靶区的基础上,采用将大地电磁测深法(简称EH4)和激电测深法有效结合的综合物探技术,进行综合分析定井.选取河南省嵩县饭坡镇汤池沟村断层带为找水实践区进行验证,实践证明,该孔孔深162 m,单位涌水量达到2.13 m3/(h·m),遵循水文地质工作与综合物探技术密切结合的原则综合定井是基岩山区断裂蓄水构造找水的有效方法.
Abstract
Fault water-impounding structures are the most common type of well formed water-impounding structures in water scarce mountainous areas of Henan Province,and searching for fault water-impounding structures is the main direction for finding water.Based on the analysis of the classification and water storage characteristics of fault water-impounding structure,this study proposed a compre-hensive well finding method that follows the principle of closely combining hydrogeological work with comprehensive geophysical explo-ration technology.Based on the selection of target areas in hydrogeological work,a comprehensive geophysical exploration technology that effectively combined the magnetotelluric sounding method(EH4)and induced polarization sounding method used for comprehensive a-nalysis and well location.The fault zone of Tangchigou Village,Fanpo Town,Song County,Henan Province was selected as the water ex-ploration practice area for verification.The practice showed that the depth of the hole was 162 m,and the unit water inflow reached 2.13 m3/(h·m).Following the principle of closely combining hydrogeological work with comprehensive geophysical exploration technol-ogy,comprehensive well location is an effective method for water exploration of fault water-impounding structures in bedrock mountain-ous areas.
