摘要
提出露天矿运输设备在运输过程中存在先下后上问题,并将此定义为垂向反向运输问题.指出实际生产中,露天矿往往只考虑运输设备克服装载点与卸载点之间的高程差带来的成本,并未考虑因垂向反向运输增加的运输成本.垂向反向运输时运输成本相对增加,主要由动力消耗增大、上下坡时速度损失和机械设备磨损增加造成的.以黑岱沟露天煤矿为例,通过对露天矿垂向反向运输中运输成本的增加值进行量化计算,为露天矿提供较为精确的运输成本计算模型,从而为露天矿开拓运输系统的设计和现场管理提供依据.
The issue of first downhill and then uphill for open-pit mine transport equipment in the transport processis is raised as a problem of vertical reverse transportation（ VRT）. It is well known that,in actual production,only the cost of overcoming vertical difference between the starting and ending points has been already considered while the transport cost of the VRT is ignored. When the VRT occurs,the other three parts should be added into the transport costs,including the increased power consumption,the speed loss during the downhill and uphill of the transport equipment,and the increased machinery wear and tear. By taking Heidaigou open-pit coal mine as an example,this paper quantifies the additional value of open-pit transport costs when the VRT occurs,and provides a more accurate model for the open-pit transport costs,so as to provide the basis for the design and management of the pit haulage system.
