以祁东煤矿某工作面为研究对象,建立6种不同覆岩结构顶板数值模型,基于FLAC软件内嵌FISH语言对软件进行二次开发,实现回采过程中顶板渗透性的动态变化,对流固耦合条件下不同覆岩结构顶板采动应力及渗透性进行了综合分析。
Taking a face of Qidong Coal Mine as a research object, six roof numerical models with different overburden structures were established. Based on FLAC software, FISH language was used to develop the software for the second time to realize the dynamic change of roof permeability during the recovery process. Under different conditions, the roof stress and permeability of different overburden structures are comprehensively analyzed.
