摘要: 运用可变模糊集理论,建立以级别特征值作为判别准则的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,并结合月山铜矿L-7#矿体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,大空区AB的级别特征值向量隶属于3级,即该采空区围岩稳定性等级为3级(稳定性差);大空区E的级别特征值向量隶属于2级,即采空区围岩稳定性等级为2级(基本稳定)。针对评价结果并结合实际,提出空区处理初步方案。

Abstract: Variable fuzzy comprehensive evaluation model of mine goaf surrounding rock stability which take level characteristics value as criterion was built by using variable fuzzy sets theory, evaluation indicators which effect the stability of goaf surrounding rock and stability grading standards were discussed. Comparison validation analysis was done on results of stability evaluation combined with goaf of orebody No.L-7 of Yueshan copper mine. The results indicate that under three kinds of weight vector, the level of the big goafs A and B was belong to level three, the surrounding rock stability of this goaf was level three (the stability was serious); the level of the big goaf E was belong to level two, surrounding rock stability of goaf was level two (the stability was basically stable). Aimed at the evaluation results and connected with practice, preliminary schemes to deal with the goaf were proposed.
