摘　　要：充填站站址作为充填系统的永久设施,是充填系统能否长久有效运行的关键之一。结合矿山技术经验与相关专家学者建议,从影响充填站站址选择的技术、经济、安全、环境4类因素中选取相关评判指标,构建充填站站址评判体系。通过层次分析法对评判体系的评判指标进行权重分配,再对各方案标准评判矩阵进行加权。运用灰色关联理论对评判体系的正确描述和有效逼近,得出实际不存在"理想方案";运用灰色关联系数将各备选方案与"理想方案"进行比较,用灰色关联度度量各备选方案与"理想方案"之间的关联程度,从而确定最优充填站站址方案。将该方法运用到某矿山充填站站址选择实例中,结合矿山实际生产技术情况,拟定4套充填站站址备选方案,运用灰色关联模型进行评判,得出4套备选方案的灰色关联度分别为:96.3%、69.5%、72.8%、86.5%,从而确定方案1充填站站址最优。As a permanent facility of filling system,the filling station site is one of the key factors deciding whether the system can operate durably and productively. Based on the technical experience of the mine and the suggestions from relevant experts and scholars,an evaluation system of filling station is established from the perspectives of technique,economy,safety and environment,which have effects on the selection of filling station sites. The AHP method is applied to distribute weights to the evaluation indexes of the evaluation system and weigh the standard evaluation matrix of each optional scheme. According to the right description and efficient approximation of the evaluation system by GRA theory,a theoretical ＂ideal scheme＂,which does not actually exist,is built and then compared with optional schemes,measuring their correlation degree based on grey relational grade. Thus,the optimum filling station site scheme is obtained. The GRA evaluation model is applied to a case of filling station site selection of a mine. Based on the technical status of actual production,4 sets of optional schemes for filling station site selection are devised,which are then evaluated by the model. The grey correlation degree of the 4 schemes are 96. 3 %,69. 5 %,72. 8 % and86. 5 % respectively,indicating the first scheme is the best option.
