摘要
庙沟铁矿通过挂帮矿回采以破解矿石缺口问题,但挂帮矿矿体形态复杂且夹岩多,不同矿体之间矿石性质差异较大,且同一矿体的不同位置矿石可选性也有较大差别。通过对挂帮矿可磨可选性的研究,确定矿石选别指标,结合采场408水平以下2#矿体矿石性质,以最终确定综合配矿指标。
Miaogou Iron ore adopts the recovery of hang-wall ore to solve the problem of lacking ores. However, the hangwall ore body has complex morphology, and there is a large amount of interlaid rock. Between different ore bodies, the ore properties have big differences. Moreover, for the same ore body, the washability of ores in different locations also owns great difference. Through the study of grindability and washability of hang-wall ore, it determines the grading index for ore. Combining the ore properties of No. 2 ore body under 408 level in the mine, it finally determines the complex ore blending index.
