基于Phase^2的巷道围岩稳定性数值模拟分析

Numerical simulation analysis of stability of surrounding rock in tunnel based on Phase^2

根据某铁矿地质资料和主要巷道工程条件,建立了基于Phase^2的矿区典型开采剖面二维有限元模型。基于模型,从应力分布角度对阶段运输大巷和斜坡道的围岩稳定性进行定性和定量分析,并提出维护巷道稳定性的措施与支护方案,为矿山巷道的维护提供了参考。

In accordance with the geological data of a certain iron mine and main tunnel engineering conditions,the typical twodimensional finite element model of the mining section was established based on the Phase^2.According to the results of numerical analysis,aqualitative and quantitative analysis of the stability of surrounding rock of the phase transport tunnel and ramp was made from the perspective of the stress distribution based on the results of numerical analysis and measures to maintain the stability of the tunnel and a support scheme were put forward as well,which can provide a reference for the roadway maintenance work in mines.
