摘要
基于乌江流域地质灾害详细调查资料,分析该地面塌陷的地质背景、形态特征和成因。地层岩性、地质构造和大气降雨构成其自然成因,而煤矿建设中的抽排地下水和爆破作业是其人为诱因。
The detailed surveys of geo-hazards in Wujiang and causes of the subsidence. Lithology, geo-tectonics and ting and blasting in coalmine construction are its man-made Basin are used to analyze the geological background, morphology rainfall constitute its natural causes while the groundwater extraccauses.
