矿产资源是国家的宝贵财富,是矿山生产建设的物质基础。矿山企业应充分利用和保护国家的矿产资源,发挥矿山的生产潜力,做到矿石在回采中贫化率最低、损失率最小、回采率最高,不断提高采矿经济效益。矿石质量的好坏和损失的大小,也是衡量一个矿山企业管理水平和生产技术水平的一项重要质量指标,因而对矿石的贫化和损失应经常进行分析和研究,针对不同类型的矿床赋存条件,不同的采矿方法,找出造成矿石贫化和损失的主要原因。从设计、施工、开采、验收各个环节采取相应措施,实行专业管理和群众
Mineral resources are the country’s precious wealth, is the material basis of mine production and construction. Mine enterprises should make full use of and protect the country’s mineral resources and make full use of the potential of the mines so that the ore has the lowest rate of depletion, the lowest loss rate, the highest recovery rate and the continuous improvement of mining economic benefits. Ore quality is good and bad and the size of the loss, but also a measure of a mining enterprise management level and production technology level is an important quality indicators, so the ore depletion and loss should be regularly analyzed and studied for different types of ore deposits Conditions, different mining methods to identify the main causes of ore depletion and loss. From the design, construction, mining, acceptance of all aspects of taking appropriate measures to implement professional management and the masses
