摘　　要：矿产资源开采中的损失与贫化问题直接关系到国家矿产资源的综合利用程度和可持续发展的问题。我国矿产资源开采中损失贫化大的问题 ,加速了资源枯竭的速度 ,缩短了矿井服务年限 ,加剧了矿产资源供求矛盾 ,造成金属大量流失、开采成本提高、经济效益差并严重阻碍了矿山的发展。文章分析了我国矿产资源开采中的损失贫化大的根源 ,并提出了解决矿石损失贫化的有效途径和低贫损开采模式。The ore dissipation and dilution affects the comprehensive utilization of mineral resources and issues concerning sustainable development. Serious ore dissipation and dilution in mining in China causes several problems such as speeding up depletion of mineral resources, shortening life of mines, aggravating contradiction between supply and demand, and so on. The paper analyzes several main factors for ore dissipation and dilution caused in mining in China, puts forth the solutions, and points out the application of low dissipation and dilution mode is a feasible and effective way to make mining enterprises competitive and profitable.
