湘中地区的岩溶发育特征与环境地质问题──以斗笠山、恩口煤矿为例

Development of Karst and Problems of Environment Geology in Central Hunan──Taking Doulishan-Enkou Mine as an example

湘中地区碳酸盐岩广泛发育，其中含煤向斜盆地的岩溶发育特征，受岩性、地貌、水文、构造运动等多因素控制，并具有水平分带和垂直分带性。而环境地质问题，主要发生在岩溶地下水排泄区。

In central Hunan there are many coalbearing synclinal basins in which carbonate rocks widelydistribute. Development of karst in these areas are controlled by many factors, including lithologic features, geologic structure, landform, hydrology, tectonic movement and so on.This paper suggests that there are horizontal and vertical zonings. The problems of environment geology occur dominantly in discharging area of karst groundwater.
