露天矿山单钻孔见矿零星锰矿体回采实践

Mining Practice of Sporadic Manganese Ore with Single Borehole in Open-Pit Mine

随着矿山的不断开采,矿石资源逐渐枯竭,如何科学回采低品位零星矿体,提高资源利用率,同时保证其经济效益成为资源匮乏的矿山企业亟待解决的问题,本文以单钻孔见矿零星矿体的开采实例,剖析了零星矿体回采所面临的问题及开采过程中应注意的事项。

with the continuous mining of mine,the ore resources are gradually exhausted,how to recover the low grade sporadic ore bodies scientifically,improve the utilization rate of resources,and ensure its economic benefit to be a problem to be solved urgently in the mining enterprises with lack of resources.In this paper,the problems encountered in the mining of sporadic ore bodies and the matters needing attention in the process of mining are analyzed.et at the +430 m level below the well,and the 412 main Pingyu drainage ditch provides the production water for the selected plant.
