摘　　要：金川集团公司二矿区目前采用机械化盘区下向进路胶结充填采矿法。在生产实践中，影响损失贫化指标的因素很多，除了设计因素外，在现场生产组织环节也有许多造成矿石损失和贫化的因素，归结起来主要有：一、二、三期进路超采造成损失与贫化、因安全回采条件原因造成损失与贫化、巷道支护带来的矿石贫化、因充填产生的溢流灰浆混入矿石造成贫化、因生产作业过程监管不到位造成的损失与贫化等。本文经过总结与分析，针对不同原因造成的损失与贫化因素提出了具体的管理措施，对提高矿山损失贫化指标，实现资源最大限度的回收与利用具有一定的指导意义。Ⅱ mine of Jinchuan group company adopts Mechanized panel underhand drift cut and fill mining method at present. In the production practice,there are many factors which can affect the loss and dilution. Apart from the design factors, at the scene production organization link there are many factors of the loss and dilution, in the aggregate, mainly include： The over mining approach. Safety mining conditions,roadway support.The overflow of the mortar filling.Production process of supervision is not in place,ctc. According to different causes of the loss and dilution factor,this paper summarizes and analysis, put forward the concrete management measures,which to improve the mine loss and dilution index, achieve maximizing recycling of resources that has certain guiding significance.
