摘　　要：采空区安全性评价是典型的多因素不相容问题,从岩石质量、环境条件和采空区赋存情况等3个方面选取代表性指标,构建采空区安全性评价指标体系.基于物元可拓理论,通过物元构造、关联度求解等操作,构建采空区安全性的物元可拓评价模型.通过隶属函数归一化处理物元量值,并用改进层次分析法修正指标权重,得到改进物元可拓评价模型.以北方某金矿为例,应用改进物元可拓模型评价其采空区安全性,并与模糊评价模型进行比较.对2组模型下评价结果相异的空区进行现场探测及数值分析,结果表明,改进物元可拓模型的评价结果与实际情况更为吻合,将其用于采空区安全性评价是合理可靠的.Goaf safety evaluation is a typical multi-factor and non-compatible problem. In the paper, representative indexes were selected from three aspects of rock quality, environmental condition and goal occurrence to built evaluation indexes system of goaf safety. Based on matter-element extension theory, matter-element extension model was established by matter-element construction and correlation solution. The origin model was improved by normalizing matter-element data via subordinate function and revising evaluation indexes＂ weights via improved AHP method to obtain improved matter-element extension model. Taking a gold mine as an example, the improved matter-element extension model was applied for goal safety evaluation while comparing the evaluation results with a fuzzy model. Scene detection and numerical analysis was carried out for the goal with different evaluation results from above-mentioned two models. The result of the improved matter-element extension model accords better with the actual conditions so it is reasonable and reliable to apply it to goal safety evaluation.
