摘　　要：矿石的损失与贫化是矿山开采中的两项主要技术经济指标,它们直接影响矿山企业的生产成本和寿命。分析了造成矿石损失、贫化的三个主要原因:地质条件复杂;施工管理的不完善,副产矿石难以管理。结合在矿山企业的生产和管理经验,提出了查明地质储量,加强现场施工管理、钻探管理、副产矿石管理,注重资料汇编,严格规章制度等措施,以降低矿石的损失和贫化,提高矿山企业经济效益。Ore loss and dilution are two main technical and economic indexes in mining,which directly affect the production cost and the life of mining enterprises.Three main causes of ore loss and dilution are analyzed:the complex geological conditions;the imperfect construction management;the difficultly management of the by-product ore.Based on the experience of production and management in mining enterprises,some measures are put forward,such as finding out geological reserves,strengthening on-site construction management,drilling management,by-product ore management,paying attention to data compilation and strict rules and regulations,so as to reduce the loss and dilution of ore and improve the economic benefits of mining enterprises.
