摘　　要：巷道围岩稳定性影响因素众多,单一的评价指标已不能准确描述围岩分类情况,然而多指标预测评价,权重往往对评价结果影响较大。采用粗糙集优化层次分析法和熵值法组合的方式对甄选的5个指标进行赋权,有效避免单一主、客观权重计算存在的误差;基于云模型计算各评价指标隶属于巷道各稳定性等级,依据综合确定度划分稳定性等级。通过现场计算,预测评价结果与实际工况一致,证明该模型构建科学合理,准确度高,开拓了巷道围岩稳定性预测评价的新思路。Stability of roadway surrounding rock is affected by many factors,so that the single evaluation index can not accurately describe the surrounding rock classification. However,multi index prediction and evaluation, the evaluation results tend to influence weight, The rough set optimization of 5 indicators combined AHP method and entropy method for the selection of the weights, effectively avoid the calculation error existing in the single subjective and objective weight; cloud model to calculate the evaluation index of the stability of roadway belonging to grade based on uncertainty on the basis of the comprehensive stability grade division. Through field calculation, the prediction result is consistent with the actual working condition. It proves that the model is scientific ,reasonable and accurate,and opens up a new method for prediction and evaluation of the surrounding rock stability of roadways.
