崩塌是新疆农一师电力公司煤矿的主要地质灾害,是地层组合、地貌特征、水动力特性及地震等因素耦合的结果。根据危岩体失稳破坏的模式,可将危岩破坏模式分为滑移式破坏、倾倒式破坏和拉裂式破坏3类。农一师电力公司煤矿区内岩质崩塌破坏的主要荷载有危岩体自重、天然状态的裂隙水压力、暴雨状态的裂隙水压力和地震力,可以构成3种荷载组合。据此,运用极限平衡理论及岩体结构理论建立了岩质崩塌破坏的计算模型,并对3类变形破坏模式的稳定性进行了计算,为岩质崩塌灾害的治理提供了理论依据。
Collapse is the main geological disasters of the Nongyi Shili Coal Mine in Xinjiang and is the result of the coupling of formation combination, topography, hydrodynamic characteristics and earthquakes. According to the failure mode of the dangerous rock mass, the failure modes of the rock mass can be divided into three types: slip type failure, dump type failure and pull type failure. The main load of rock mass collapse in the coal mines of Nongyi Shi Electric Power Company is composed of dead weight of rock mass, fissure water pressure of natural state, crevice water pressure of rainstorm state and seismic force, which can constitute three kinds of load combination. Based on this, the calculation model of rock mass collapse and failure is established by the theory of limit equilibrium and the theory of rock mass structure, and the stability of the three types of deformation and failure modes is calculated, which provides a theoretical basis for the management of rock mass collapse.
