高密度电法探测煤矿地下水及溶岩空洞效果

Application of High-density Electrical Method Detecting Groundwater and Cave in Coal Mine

电法勘探是利用岩(矿)石间电磁学性质及电化学性质的差异作为基础的一种勘探方法。其应用领域十分广泛,可在空间、陆地、海洋、地下等各种环境内进行。高密度电法具有观测工作简单、工效高、采集的信息量大的优点;能勘测到地质灾害或岩土工程中诸如隐伏溶洞、地下暗河、节理裂隙等地质问题。利用高密度电法勘查煤层顶板的富含水区以及岩溶空洞的范围,能为煤矿企业预防突水事故的发生提供依据。

In the foundation of differences between electromagnetism and electrochemical properties in rock stone,electric prospecting is exploration method.It applys in different fields,such as space,land,sea,underground and so on.,with features of simple detecting work;High efficiency;High quality information,High-density electrical method detects ecological disasters,concealing cave,underground river,joint fissures in eotechnical engineering effectively.High-density electrical method explores coal seam rich in water and measure karst empty range accurately,which provides basis of preventing coal mining enterprises from accidents.
