中文摘要：

针对倾斜煤层露天矿纵采转横采条件下,随着开采程序的改变,导致内、外排土程序、剥离运距、提升高度、年征地面积及货料流发生变化。针对这一问题,建立排土场建设发展的经济模型,从露天矿山内外排货料流规划,外排土场运输、征地,内排土场动态发展形态及内外排剥离物提升高度等因素出发,优化露天矿生命周期内内外排土场建设发展程序。结合新疆准东露天煤矿首采区由纵采转横采的过程中,进行实例研究。

英文摘要：

Under the conditions of vertical mining to horizontal mining in inclined coal seam open-pit mine, with the change of mining program, it leads to the changes of inner and outer dump program, stripping transportation distance, lifting height, the area of land and material goods flow. To solve this problem, the mine builds the economic model of dump construction development. From the inner and outer row of open-pit mine planning stream, outer dump transportation, land acquisition, inner dump dynamic development and the inner and outer rows peeling lifting height and other factors, the mine optimizes the inside and outside dump construction development program in the lifecycle. The article combines the process of vertical mining to horizontal mining to carry out research in Zhundong Open-pit Mine first mining area .
