摘要
在露天转地下开采过程中,为了研究大新锰矿边坡岩体稳定性及其对地下开采的影响,分析了该矿的边坡稳定性因素,探讨围岩移动变形、应力分布特征和破坏机理。以大新锰矿典型的中部矿体的回采为工程背景,采用FLAC3D程序创建数值模型,对处在回采的矿房上覆边坡岩体进行失稳分析,给出了再开采过程中容易产生失稳破坏的部位及失稳破坏机理,对今后矿山地下开采提供合理的采矿参数和支护方法。
Daxin manganese in combined mining to underground in order to study the stability of slope rock mass and its influence on underground orebody mining, studied and analyzed the factors of the slope stability of the mine, probes into the surrounding rock deformation, stress distribution and failure mechanism. Smoothly for mine production safety, and provide a scientific value. In the eastern part of the daxin manganese ore body mining as the engineering background, using FLAC3D program to establish a three dimensional numerical model of orebody to underground, on the stability of open pit slope engineering in daxin manganese ore and the simulation results are analyzed, and gives the prone to instability in the process of manganese ore in mining area and instability mechanism, puts forward the reasonable supporting proposals to underground mining in the future.
