摘　　要：矿产资源开采中的损失与贫化关系到资源利用程度,降低损失贫化,即可减少资源浪费,增加矿山服务年限。本文分析了大岭矿采场矿石贫化与损失的原因,从完善和改进采矿方法、优化采场分层设计、改善采场的安全条件、提高充填体强度并减轻充填体的损坏、强化采场施工质量管理五个方面提出了降低大岭矿矿石贫化率与损失率的途径。The loss and impoverishment in the mineral resource mining relates the resources utilization degree, reduces the loss and impoverishment, then reduces the resources waste, increase mine service life. This article has analyzed the impoverishment and the loss reason of the Daling ore stoping, From five aspects of consummating and improving mining method, optimizing stope lamination design, improving stope safety condition, enhancing the backfill body intensity and reducing the body damage, strengthening the quality management of stope construction, then proposed the way to reduce the impoverishment rate and the loss factor of Daling ore.
