某煤矿采空区的地裂缝、地面塌陷地质灾害发育,危及矿区居民的生命财产。本文在分析地质灾害环境、灾害特征的基础上,从地质定性分析和定量力学分析角度对煤矿采空区顶板的稳定性做出了评价,认为地裂缝、地面塌陷等地质灾害是由地下煤矿采空区顶板失稳、逐渐向地表发展而成,为防治地质灾害提供了依据。
Ground fissures in a coal mined area, the development of ground subsidence geological disasters, endangering the lives and property of residents in the mining area. Based on the analysis of geological disaster environment and disaster characteristics, this paper evaluates the stability of coal mine roof from the view of geological qualitative analysis and quantitative mechanics analysis. It is concluded that geological disasters such as ground fissures and ground subsidence are caused by underground coal mining Unstable roof space, and gradually developed from the surface to provide a basis for the prevention and control of geological disasters.
