南芬露天矿北山采区道路和开采的优化设计

Optimization Design on the Roads as well as Mining in Northern Hill mining area of Nanfen Open Pit Mine

针对南芬露天矿多分期分区开采的特点,规划不同分期分区的剥岩进度,适时优化采区的运输道路和开采计划,形成近距离运输道路,并发挥破碎-胶带运输系统的优势,缩短生产车辆的运距,降低矿山运营费用,经济效益可观。

In accordance to the multi--phases and multi--areas mining characteristics in Nanfen Open Pit Iron Mine, planning stripping progress within each phase and each area, optimizing haulage roads in the mining area as well as a mining plan, thus enabling short distance haulage roads, maximizing performance of the breaking-- belt conveying system can shorten haulage distance of production trucks and reduce operating cost of the mine. These can bring great economic benefit.
