摘　　要：应用可变模糊集理论,建立矿山采空区围岩稳定性可变模糊综合评价模型,初步探讨了影响采空区围岩稳定性的评价指标以及稳定性分级标准,并结合某矿山采空区实例对稳定性评价的结果进行了对比验证分析.结果表明:在3种权重向量下,样本级别特征值向量均隶属于3级,即该采空区围岩稳定性等级为第3级(稳定性差).Based on variable fuzzy sets theory,the comprehensive evaluation system model of the stability of surrounding rock of mined-out area was set up.The evaluation indexes that influence the stability of surrounding rock of mined-out area and the grade indices for appraisal of stability were primarily explored.The evaluation results of the stability calculation were compared and analyzed using a mined-out area as an instance.The results of the study show that under three kinds of weight vector,the eigenvector of the sample belongs to the third grade,meaning the stability of mined-out area is level 3（the stability is bad）.
