摘　　要：在拟合破裂岩石强度和变形特征的基础上，运用FLAC3．3对巷道支护阻力与围岩位移量的关系进行了模拟，分析了不同岩性条件下，支护阻力对围岩位移量的控制程度，并同人工神经元网络的拟合结果进行了对比。提出了支护阻力对控制软岩巷道具有重要作用及敏感作用范围的观点。在铁法矿区进行了工程实践，有效地控制了深井软岩巷道。Based on approximating the strength and deformation feature of broken rock, the relationship between support resistance and displacements of surrounding rock is simulated by FLAC3. 3. The degree of support resistance affecting displacements of surrounding rock is analyzed, whose result is contrast with regression result by ANN. It is pointed out that the support resistance has an important effect in the control for soft rock in deep mine and has a sensitive area of action. The engineering practice is carried on in Tiefa mining area,and the soft rock in deep mine is controlled effectively.
