| 摘 要： | 为了对软岩巷道顶板的位移进行有效预测,防止因顶板位移过大而使得巷道破坏带来损失,利用改进Verhulst模型与灰色效果测度理论对软岩巷道顶板破坏规律进行分析。利用位移监测手段对矿山部分巷道顶板位移进行监测,利用预测精度更高的改进Verhulst模型对检测结果进行分析,得到巷道顶板的最终位移,并判断巷道破坏情况。对影响巷道顶板位移的顶板地应力、围岩质量、巷道跨度以及支护方式等因素灰色效果进行综合测量,将测度值与巷道破坏情况相结合,得到矿山各巷道顶板的宏观稳定性评价结果。研究结果表明:当灰色预测效果测度值在0～0.705 1之间时,巷道是比较稳固的,为巷道进行二次支护提供了依据。
