【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]:In order to determine the location and duration of coal mining in open pit, the basic principle and statistical analysis method of open pit mining are used to analyze the characteristics of the development and change of the open pit coal mine in the new period and its influence on the reserve position and the retention period of the coal reserves. The relationship between the location of the coal quantity and the distance of the inner row is established, and the optimization model of the reserve position of the coal reserves is established, and the relationship between the period of coal mining and the cost of the exfoliation, the cost of transportation and the time value of the funds is studied. The optimization model of the reserve period of the reserve is established. The economical and reasonable reserve of coal mining in the mine is 6.5 months, and the amount of coal mining should remain in No. 1 coal seam. The result shows that the optimization model can be used to guide the production of open pit, reduce the cost of stripping effectively and improve the economic benefit.
