摘要: 采用ANSYS软件对焦家金矿望儿山分矿的Ⅱ级岩体进行不同进路参数下的采场稳定性分析,进路宽度增大时,一步进路充填体内的应变能也越来越大,当一、二步进路宽度为5 m时,充填体本身不能承受太大的应力而破坏,由此得出:望儿山分矿Ⅱ级岩体进路最佳尺寸为4 m×4.5 m(高×宽)。

Abstract: Slope stability analysis of different approach parameters was done on Ⅱ grade rock mass of Wangershan branch mine of Jiaojia gold mine by ANSYS. The strain energy of filling body of step approach increases with width of approach increasing. When width of one and two step approach was 5 m, filling body damaged due to could not bear too much stress. It indicates that approach best measurements of Ⅱgrade rock mass of Wangershan branch mine are 4 m×4.5 m (height×width).

Key words: Unstable rock mass, Approach mining method, Mining Parameters
