FLAC3 D在采场进路稳定性分析中的应用

摘要

为了研究回采时受扰动的围岩对采场稳定性的影响，文中采用三维数值分析软件FLAC3D对某铬铁矿上向进路充填法的进路回采进行模拟分析，计算了进路不同位置的顶板变形量，结果表明，根据设计中选取的采场参数，进路在回采的过程中是相对安全的。%In order to study the stope stability when affected by disturbance of surrounding rock, the three-dimen-sional numerical analysis software FLAC3D was used to analyze the upward drift of a chromite mine. The roof de-formation of the different position was calculated by FLAC3D,and the result suggests that the stopes are relatively safe in mining process by using the designed parameters.
