摘要
红泥坡铜矿具有资源量大、品位高(达1.67%)、易选、矿岩稳固等特点,但地表覆盖农田、部分工业设施及村落,属于复杂典型的“三下开采”矿床。因此针对红泥坡铜矿地表设施安全问题和下一步矿体回采安全问题,分别提出了全尾砂+级配碎石膏体胶结充填方案和分级尾砂胶结充填方案,并且对这两个充填方案从系统建设成本、运营成本等主要技术经济指标进行了系统对比分析。结果表明:全尾砂+级配碎石膏体自流+泵送充填工艺方案具有运营成本低、充填总成本(24.78元/t)低、矿石回收率高等优点,最终确定全尾砂+级配碎石膏体自流+泵送胶结充填方案。
Hongnipo Copper Mine is characterized by large amount of resources,high grade(up to 1.67%),easy separation and stable rock.But the surface covers farmland,part of industrial facilities and villages,which is a“three mining”deposit with complex mining conditions,so aiming at the safety of surface facilities and the safety of the next orebody mining,the scheme of cemented filling with full tailings+graded crushed gypsum body and the scheme of cemented filling with graded tailings are put forward respectively.In addition,the two filling schemes are systematically compared and analyzed from the main technical and economic indicators such as system construction cost and operation cost.The results show that the scheme of full tailings+graded crushed gypsum body gravity flow+pumping filling has the advantages of low operation cost,low total filling cost(24.78 yuan/t)and high ore recovery rate.Finally,the scheme of full tailings+graded crushed gypsum body gravity flow+pumping cemented filling is determined.
