摘要
地下煤层的开采会形成大范围的采空区,继而破坏上覆岩层结构,诱发山体滑坡。以山西某采动滑坡为例,采用有限元法,针对边坡在地下煤层采空的情况,对其进行建模分析其位移场的变化,同时探讨出采动滑坡的变形过程。
Underground coal mining can form a wide range of mined-out area, and then destroy the overburden structure, induce landslides. taking a mining landslide in Shanxi province as an example, the finite element method, in the presence of side slope in underground coal goaf, carry on the modeling analysis of the change of the displacement field, and also discusses the mining landslide deformation process.
