高密度电法在湖南省常德市董家咀矿区水泥用石灰岩矿水文地质勘查中的应用

Application of high density electrical method in hydrogeological exploration of Dongjiazui limestone mining area in Changde, Hunan province

为了调查石灰岩矿区水文地质条件,查明矿区各种地质构造以及地下水分布、运移特性,为矿区开采、设计提供参考。采用高密度电法对湖南省常德市董家咀矿区水泥用石灰岩矿水文地质条件进行勘查,根据分析,矿区第四系覆盖层土体分布较厚,岩溶及充水破碎带较发育,水文地质条件复杂,在矿区开采前需提前采取措施,以减少地下水对矿山未来开采的影响。

In order to investigate the hydrogeological conditions of limestone mining area, find out the fracture zone of geological structure and the distribution and migration characteristics of groundwater, and provide reference for mining and design of mining area. The high-density electrical method is used to investigate the hydrogeological conditions of Dongjiazui mining area in Changde. According to the analysis, the broken rock and soil mass in the mining area is widely distributed, with a large area and water filling zone. Measures should be taken in advance in mining to reduce the impact of groundwater and broken rock and soil mass.
