摘要
以山东黄金的骨干矿山为工程背景,建立了以级差边际品位为核心的盈亏平衡模型,对不同工程控制下的低品位资源进行评估,分析计算级差边际品位,研究制定开发利用方案。研究结果在矿山实施后,大幅增加了矿山的可利用资源储量,对延长矿山服务年限、增加企业经济及社会效益具有重要意义。
By taking differential cut-off grade as the key issue,a break-even model was built up to realize the evaluation of low-grade resources in different production stages.In the case study on the core members of Shandong Gold Group,the differential cut-off grades were calculated to establish the development and utilization plan of low-grade resources.The application of the research results brings remarkable achievements,such as increasing the available reserves,prolonging the service life of mine,as well as getting more economic and social benefits.
