金矿石的品位,对矿山生产是十分重要的指标.例如坑口矿石的出矿品位,选矿厂的原矿品位、精矿品位、尾矿品位等,每天都要进行记录、统计分析并及时上报生产管理机构,使之对过去的生产成果作出分析和判断,对未来的生产过程作出决策,对经常性的生产管理和经济核算起着重要作用.特别是当矿山编制年、季或月的采掘计划时,需要估计下一年、季或月的矿石品位(如地质品位、出矿品位、精矿品位等).目前,不少矿山估计矿石品位时,多数以经验来确定,因而往往与实际出入较大,甚至编写的年、季或月的采掘计划失去对生产的指导意义.因此,如何预报矿石品位成为当前一个重要的研究课题.
The quality of gold ore is a very important indicator for the production of mines, for example, the exit grade of pit ore, the ore grade of concentrator, the grade of concentrate, the grade of tailings, etc, should be recorded, analyzed and reported to production management Agencies to make an analysis and judgment of past production achievements and to make decisions on future production processes, which play an important role in regular production management and economic accounting, especially when mines make annual, seasonal or monthly mining plans , Need to estimate the next year, quarter or month ore grade (such as geological grade, ore grade, concentrate grade, etc.) At present, many mines to determine the grade of ore, most of the experience to determine, and therefore often with the actual access to more Large and even prepared year, season or month of mining plans lost the guiding significance of production.Therefore, how to forecast ore grade has become an important research topic.
