万山区中朝溪锰矿水文地质及工程地质特征

Hydrogeological and Engineering Geological Characteristics of Zhongchaoxi Manganese Mine in Wanshan District

近年来,随着矿山的开采,矿山问题日益突出,故对矿山水文地质、工程地质特征研究是十分必要的,文章通过对矿区含水岩组富水性、主要破碎带水文地质特征、矿井现状的水文地质特征、地下水动态变化特征,研究分析了矿区的地下水补径排条件;按不同层位岩性特征,划分出4个工程地质岩组,对矿层顶、底板稳定性进行评价,为矿山进一步开采提供参考。

In recent years,with the mining of mines,mine problems become more and more prominent,so it is necessary to study the characteristics of hydrogeology and engineering geology of mines.By analyzing the water yield property in water-bearing formation,hydrogeological characteristics of major fracture zones and of current shafts,as well as the dynamic changes of underground water,the conditions for supplement,runoff and draining of underground water are investigated.According to the lithologic characteristics of different strata,four engineering geological rock groups are divided,and the stability of the roof and bottom of the ore bed is evaluated,which provides a reference for the further mining of the mine.
