摘　　要：为提高露天煤矿经济效益及确保安全生产,对排土场参数及建设发展程序进行优化,有效保障露天煤矿排土工程安全及控制排土成本。通过优化露天煤矿外排土场参数,以排土场剥离运输功最小为基本原则,优化排土场段高;提出4种露天煤矿卡车外排土场排土程序方案;根据不同排土程序方案下动态绘制排土场排弃量与加权运输距离曲线,建立排土场运输费用现值模型及排土场征地费用现值模型。结果表明:以内蒙古元宝山露天煤矿为研究对象,根据总费用最少为原则,确定四合村北排土场方案为最佳排土场位置,根据不同排土程序条件下,优化元宝山露天煤矿新建卡车排土场合理排弃段高为26 m,同时推荐采用对向发展式排土程序。露天煤矿逐年动态发展运输、征地费用不同;排土场运输、征地现值模型简单可靠,对于解决其他露天煤矿卡车外排土场设计优化问题具有一定的参考价值。In order to improve the economic benefit of the surface mine and to ensure the safety production,an optimization was conducted on the dumping site parameters and construction and development program,the dumping engineering safety of the surface mine was effectively protected and the dumping cost was controlled. With the optimization on the outer dumping site parameters of the surface mine,based on the minimum stripping and transport work of the dumping site as the basic principle,the section height of the dumping site was optimized. There were four truck dumping program planes of the outer dumping site in the surface mine provided. According to different dumping program plan,dump discharge volume and average weighted transport distance curve was dynamically drawn and the current value model of the transport cost in the dumping site and the current value model of the land acquisition cost for the dumping site were established.The results showed that based on Inner Mongolia Yuanbaoshan Surface Mine as the study object,that the best dumping location was determined at Si He Village based on the total cost least principle. Under different dumping process conditions,the reasonable dumping bench height was optimized to 26 meters in the new truck external spoil pile,and the opposite direction development dumping process was adopted. the annual dynamic development and transport of the surface mine and the land acquisition cost would be different. The model of the transport in the dumping site and the land acquisition cost would be simple and reliable and would have certain reference value to solve the design and optimization of the truck and outer dumping site in other surface mine.
