方田煤矿开采引发孝坪集镇岩溶地面塌陷可能性的分析与对策

Analysis and Strategy for Karstic Collapsein Xiaoping Town Caused by the Exploitation of Fangtian Coalmine

在详细阐明煤层顶底板岩溶充水含水层及断层水文地质特征的基础上,根据岩溶发育规律对矿井拟开采范围进行了水文地质条件分区。分析了矿山在水文地质条件复杂区与中等区开采引发孝坪集镇岩溶地面塌陷的可能性。针对本矿开采排水可能引发孝坪集镇岩溶地面塌陷问题,提出了科学的预防措施,对方田煤矿开采及孝坪集镇地质环境保护有一定指导意义。

Basing on the detailed illustration of the hydrogeological characteristics of water-filled karst layer of roof and floor of seam and fault, the author divided the proposed mining area from hydrogeological condition, which take the law of karst development into account. The author analysis the possibility of karst collapse in Xiaoping town, which was caused by the exploitation in the complex and middle hydrogeological area. The author put forward the scientific precautions for the karst collapse problem probably caused by the exploitation and drainage in the coalmine, which can direct the exploitation in Fangtian coalmine and the geological environment protection in Xiaoping Town.
