摘要
煤炭采空区形成的塌陷,对地面建筑和土地极易造成危害,本文通过对沙沟峁煤矿形成采空区的基本特征、变形与破坏特征的分析,以及对该煤矿采空区稳定性的评价,为以后的治理提供了依据。
Mined-out area is formed by underground coal mining activity,and will damage after a certain time,then causes hazard to the ground buildings and land. The paper analyzed the basic characteristics of the mined-out areas in Shagoumao Coal Mine and assessed the stability of mined-out area. The research can provide the basis for mine goaf governance.
