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。
為瞭研究迴採時受擾動的圍巖對採場穩定性的影響，文中採用三維數值分析軟件FLAC3D對某鉻鐵礦上嚮進路充填法的進路迴採進行模擬分析，計算瞭進路不同位置的頂闆變形量，結果錶明，根據設計中選取的採場參數，進路在迴採的過程中是相對安全的。

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.
