为了解断层对深部采矿的影响,利用天然电场选频法对北矿区断层进行勘探。结果表明,顺层断层是良好的地下水径流通道,特别是五通组与黄龙组以及黄龙组与栖霞组间的不整合面,发育顺层断层和岩溶,是地表水和浅部地下水向深部采矿区流动的地下径流通道;倾向断层连通不同含水层、顺层断层和不整合面,将地下径流通道连通成网。断层对深部采矿安全影响较大。
In order to understand the influence of faults on deep mining, the natural electric field frequency selection method is used to prospect the faults of North Mining Area. The results show that the fault is a good groundwater runoff channel, especially between the Wutong Formation and the Huanglong Formation and the unconformity between the Huanglong Formation and the Qixia Formation. Stratigraphic faults and karst are developed, and the surface water and shallow groundwater are deep mining Zone flow of underground runoff channel; dip fault connectivity of different aquifers, bedding fault and unconformity, the underground runoff channel connected into a network. Faults have a great impact on the safety of deep mining.
