金川龙首矿采场出矿品位状况调查

矿山出矿镍品位的高低直接影响到矿山企业的经济效益，本文通过龙首矿以往生产勘探、基建探矿资料的研究，按采场实测地质平面图为单元分中段、分采区，用采场或盘区的铜、镍系统采样分析结果重新圈定了矿体，并与2012年采掘计划镍品位进行了对比，查清了回采区段内各采场品位变化情况，为公司金属走向调查和矿山采掘技术计划编制提供了依据。

The level of ore nickel grade impacts on the economic benefits of mining enterprises. Base on past production explora- tion and infrastructure prospecting information of Longshou mine, according to stope measured geological plan unit and sub - middle and sub - mining area, this article re - delineated the ore body with sampling and analysis results of the stope or panel copper and nick- el system, and were compared with nickel grade of the 2012 mining plan, and identified the grade variation of the stope, to provide a basis of metal nvestigation and the preparation of mining technology plan for the company.
