本文概要阐明了应用地质勘探剖面建立的矿床模型,在计算机上对南芬露天铁矿模拟开采研究生产剥采比的方法,扩帮过渡和优化生产剥采比的准则,陡帮开采生产剥采比的分布规律及影响因素。给出了南芬露天矿技术可行、经济上有利的均衡生产剥采比的分布,指明了应用陡帮开采比缓帮开采可以节约总投入的贴现额达2.0亿元;理论上指出了继续挖掘陡帮开采经济潜力的技术方向:改变开采延深方向,增大台阶高度,推迟扩帮过渡时间。
This paper summarizes the application of geological prospecting section established deposit model, on the computer simulation of Nanfen open-pit iron ore mining production and exploitation ratio of the method of expansion and expansion of transition and optimization of production stripping ratio criteria, steep to help mining production stripping Ratio of distribution and influencing factors. Given the technical feasibility of Nanfen open-pit mine, the economic benefit of a balanced production stripping ratio distribution, indicating that the use of steep aided mining than slow to help mining can save a total investment discount amount of 200 million yuan; theoretically pointed out that continue to dig Steep help mining economic potential of the technical direction: to change the direction of mining deepening, increase the height of the stage, postponed expansion of transitional time.
