【摘要】：我国经济进入新常态,钢铁冶金业大力淘汰过剩产能,加之世界铁矿市场疲软,铁矿价格持续低迷,矿山企业面临降低成本的巨大压力。对于露天矿山,提高帮坡角是充分回收资源、降低生产成本、增加矿山效益的重要手段。鉴于此,通过Opmetalminer软件建立矿床数值模型,按0.5°步长优化得到不同上盘帮坡角所对应的境界内矿岩量、总盈利、开采范围和开采深度的变化情况,通过对比分析给南芬露天矿降低生产成本提供决策。研究表明:随着帮坡角度数的提高,与基准境界相比,采出矿石量有所增加,剥离岩石量有增加有减少,总盈利增加,开采范围和开采深度在不同区域变化趋势相反。
[Abstract]:China's economy has entered a new normal, the iron and steel industry has vigorously eliminated excess production capacity, coupled with the weakness of the world iron ore market, iron ore prices continue to be depressed, mining enterprises are faced with great pressure to reduce costs. For open-pit mines, increasing slope angle is an important means to fully recover resources, reduce production costs and increase mine efficiency. In view of this, the numerical model of ore deposit is established by using Opmetalminer software, and the variation of ore rock quantity, total profit, mining range and mining depth in different upper slope angle corresponding to slope angle are obtained according to 0.5 掳step optimization. This paper provides a decision to reduce the production cost of Nanfen opencast mine through comparative analysis. The results show that with the increase of slope angle, the amount of ore produced is increased, the quantity of peeled rock is increased and the total profit is increased. The variation trend of mining range and depth in different regions is opposite.
