摘要
结合某矿山工程实际情况,利用三维有限元数值模拟软件3D-σ对片理状岩体下中段主运输巷道的布置方式进行了数值模拟,通过对不同布置方式下的巷道岩体最大主应力和顶板安全率进行分析,论证了巷道布置的合理性,得到了片理状岩体巷道的最佳布置方式。
A three-dlmensional model was established for underground mine by using 3D-Sigma software to analyze tunnel arrangement in schistosity rock. Maximum principal stress of tunnel surrounding rock and safety ratio of roof was studied to approve the feasibilities of tunnel arrangement, showing the best way about tunnel arrangement in schistosity rock.
