Under the geological conditions and the engineering situation of the mine, which goes from an open -pit to the underground mine. 7 main factors that influence the stability of the boundary pillar are taken into consideration, including the thickness of the boundary pillar, the compressive strength of the ore, the tensile strength of the ore, the open-pit depth, the joint distribution, the mining method of the underground mine and the seeper of the open-pit. The unascertained measurement function is obtained based on the actual situation of the mine; the weights of all indexes are calculated by using the entropy theory, the safety evaluation results of the boundary pillar can be obtained based on the credible degree recognition criteria. Using this model, the safety of the boundary pillars of three typical mines is evaluated. It is indicated that the unascertained measurement assessment results agree well with the actual records, and the scheme of the Xinqiao Mine's boundary pillar is feasible. The results show that this model provides an effective method to evaluate the safety of the boundary pillar. The establishment of the uncertainty safety evaluation model highly depends on the grading standards and there is no uniformly accepted grading standards yet, further studies are needed to solve this

articleAbstract=运用未确知测度理论,建立露天转地下境界顶柱安全性评价模型。从露天转地下矿山的地质条件和工程状况出发,选取境界顶柱厚度、抗压强度、抗拉强度、露天坑深度、节理分布、地下矿采矿方法和露天坑积水7项指标作为判别指标。根据实际情况建立未确知测度函数,采用信息熵理论获得各判别指标的权重,并依照置信度识别准则进行等级判定,最后得出境界顶柱的安全评价结果。采用该评价模型对新桥硫铁矿、石人沟铁矿和获各琦铜矿3座典型的露天转地下矿山境界顶柱的安全性进行评价,评价结果与已经完成露天转地下矿山的境界顶柱实际情况符合较好,因此,根据评价模型的评价结果,推断新桥硫铁矿采用的境界顶柱方案是可行的。研究结果表明,此安全评价模型可行,为境界顶柱安全性评价提供了一种有效的方法。,
