| 摘 要： | 为了确定经济合理的露天矿备采煤量留设位置和保有期，运用露天开采基本原理与统计分析方法，分析新时期露天煤矿的发展变化特点及其对备采煤量留设位置和保有期的影响；以经济效益最优为判断准则，研究复合煤层露天矿备采煤量留设位置与内排运距的关系，建立备采煤量留设位置优化模型；研究季节性剥离露天矿备采煤量保有期与剥离成本、运输成本以及资金时间价值的关系，建立备采煤量保有期优化模型。以内蒙古东部地区某露天矿为研究实例，确定了该矿经济合理的备采煤量保有期为6.5个月，备采煤量应全部留在1号煤层。研究结果表明：该优化模型可用于指导露天矿生产，有效降低剥离成本，提高经济效益。

| Abstract: | To ascertain economic setting location and remaining period of blocked-out coal reserves in surface mine, with the basic principle of the surface mining and statistical method, we analyzed the characteristics of developing change and its influence on setting location and remaining period of blocked-out coal reserves. Based on the principle of optimal economy benefit, the relationship between setting location of blocked-out coal reserves and internal dumping transportation distance in multi-coal seam surface mine was studied, and an optimization model of setting location of blocked-out coal reserves was built. We also studied the relationship between remaining period of blocked-out coal reserves and stripping cost, transportation cost, time value of money, and built an optimization model of remaining period of blocked-out coal reserves. Taking a surface mine in east of Inner Mongolia as an example, we ascertained the economic remaining period of blocked-out coal reserves in this surface mine should be 6.5 months, and blocked-out coal reserves should be set in 1# coal seam. The results show that the optimization model can guide production, decrease stripping cost and increase economic benefit of surface mines. |
