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)。

Abstract:

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).
