摘要
结合黑沟露天采场精细化采矿、配矿的实际情况,对矿石质量测量过程中取样方法进行优化改进,优化结果包括矿体位置、矿体形态、矿石量、矿石品位等图表数据.此次为指导生产精细化采矿、配矿提供重要依据.通过岩(矿)纵切取样测量工作,降低了盲小矿体损失贫化率,提高了资源利用率.
Abstract
Combined with the actual situation of fine mining and ore blending in Heigou open pit stope,the sampling method in the process of ore quality measurement is optimized and improved,and the chart data of ore body position,ore body shape,ore quantity and ore grade are obtained.It provides an important basis for guiding the production of fine mining and ore blending.Through the rock(ore)longitudinal cutting sampling survey,the loss and dilution of blind small ore body are reduced,and the resource utilization rate is improved.
