矿床开采中的损失与贫化加速了矿产资源枯竭的速度、缩短了矿井的服务年限、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、环境污染、经济效益差并严重阻碍了矿山持续健康地发展。本文从国家矿产资源开来政策、采矿方法、回采工艺、品位指标、企业管理等方面分析、探讨了我国矿床开采中损失贫化大的根源，提出了从政策制度、采矿方法和回采工艺、动态品位优化以及利用空间技术和计算机模拟技术等方面来降低矿石损失与贫化的有效对策，并介绍了低贫损开采模式及其应用前景。
The loss and depletion of mineral deposits have accelerated the depletion of mineral resources, shortened the service life of mines, exacerbated the contradiction between supply and demand of mineral resources, caused a great loss of metals, raised the cost of mining, environmental pollution and poor economic benefits and seriously hindered the operation of mines Sustained and healthy development. Based on the analysis of national mineral resources development policy, mining method, mining technology, grade index and business management, this paper discusses the causes of large loss and depletion in the mining of mineral deposits in our country, and puts forward some suggestions from the aspects of policy system, mining method and mining technology, Grade optimization and effective countermeasures to reduce the loss and depletion of ores by using space technology and computer simulation technology. The low-loss mining mode and its application prospects are also introduced.
