通过地质调查、钻探、物探等方法对淮南大通浅覆盖岩溶区岩溶塌陷的分布特征及诱因进行了分析,结果表明,大通浅覆盖岩溶区岩溶塌陷主要分布于下伏奥陶系马家沟组地层之上,以及构造发育区和松散层粉土含量较高区,岩溶塌陷主要受岩石溶蚀程度、强烈地下水动力条件及松散层厚度、成分等控制。结合岩溶塌陷发育特征及场地具体条件,探讨了大通浅覆盖型岩溶区土地利用的可行性,为土地综合开发利用提供参考。
The distribution characteristics and causes of karst collapse in Datong shallow covering karst area of Huai’nan were analyzed by means of geological survey, drilling and geophysical prospecting. The results show that the karst collapse in Datong shallow covered karst area mainly distributes in the lower Ordovician Majiagou formation , As well as tectonic development zone and loose layer silt content higher karst collapse is mainly controlled by the degree of rock erosion, strong groundwater dynamic conditions and loose layer thickness, composition and so on. Combined with the development characteristics of karst collapse and site specific conditions, the paper discusses the feasibility of land use in Datong shallow covered karst area and provides reference for the comprehensive development and utilization of the land.
