实地调查了平顶山矿区八矿井田范围内地面塌陷和地裂缝的分布情况,结合八矿的开采历史、区域地质概况以及目前煤矿的开采情况,阐述了采空区的分布范围与地面塌陷及地裂缝的发育特征的关系。然后分析了八矿井田范围内地面塌陷及地裂缝的展布规律,并对其可能引发的地质灾害进行了危险性评估,提出了针对地面塌陷及地裂缝的防治措施。
Field investigation of the distribution of ground subsidence and ground fissures in the mine area of the eighth mine in Pingdingshan mine area. Combined with the mining history of the eighth mine, the regional geology survey and the current mining situation, the paper expounds the distribution range of the goaf and the ground subsidence and ground fissure The relationship between the developmental characteristics. Then the distribution rules of ground subsidence and ground fissures in the minefield of No.8 mine are analyzed, and the risk assessment of the possible geological disasters is carried out. The prevention measures of ground subsidence and ground fissures are put forward.
