【摘要】 为准确评判石膏矿采空区稳定性这一涉及因素众多的复杂系统问题,本文甄选影响石膏矿采空区稳定性的13个指标,探讨这些指标的评判方法;基于集对分析理论,由影响采空区稳定性的样本实测指标值与采空区稳定性标准构建集对,通过联系度描述集对关系并进行石膏矿采空区稳定性分类;运用此集对分析模型对一石膏矿采空区稳定性进行评价,结果表明,评价结果准确﹑计算简单﹑分类结果可信,为采空区稳定性评价开辟一条新的途径,并对其他岩体稳定性评价具有借鉴意义。更多还原

【Abstract】 In order to evaluate the stability of goaf in gypsum mine accurately that refers to many factors,13 indexes which affect the stability of goaf were selected,the evaluation methods for these indexes were discussed in this paper;based on the theory of set pair analysis,the set pair was constructed with measured values that influence the stability of goaf and the standard of the stability of goaf,the connection of the set pair was described by connection degree and the stability of goaf on gypsum mine was classified.A case study,the stability of the goaf on one gypsum mine was evaluated by this model.The results shows that the evaluation is right,the calculation is simple,the results of classification are feasible;opens up a new way for the stability evaluation of mined out area,and has reference meaning for other stability evaluation of rock.更多还原
