摘要
当前露天煤矿端帮资源探入式开采条件下,边坡稳定性分析未充分考虑采硐影响的具体情况。笔者对原有的刚体极限平衡法进行改性,同时结合拉格朗日有限差分法分析边坡稳定性,并对边坡稳定系数的计算方法进行修正和完善,采用理论计算和数值模拟相结合的研究方法,论证了某露天煤矿端帮探入式开采的可行性和安全性,该矿实现了最高月产量为6万t的好成绩,取得了良好的经济效益和社会效益。
Under the current resource probing mining in an open-pit coal mine, the stability a- nalysis of slope neglected the influence of mining adit. Therefore, the slope stability was studied by the modified Rigid Limit Equilibrium Method and the Lagrange Finite Difference Method. The calculation of the stability parameters were improved. The theoretical calculation and numerical simulation were used to validate the feasibility and safety of the probing mining of the end-slope. The mine realized the highest monthly output of 60,000 ton, which has achieved better economical and social benefits.
