摘要： 将汽车运输露天矿的运输设备与物料匹配关系分为统一运输、独立运输、组合运输3种类型,分析了难度最大的组合运输的车流特点,并充分考虑统一运输、独立运输的兼容性,提出了满足各种矿岩配车需求的通用车流规划数学模型.讨论了模型在3种类型下的应用差别,论述了简化模型计算步骤及提高模型计算速度的办法.实验结果不仅验证了模型的通用性,而且还证明在卸矿点与装岩点或卸岩点与装矿点的距离较近时,矿岩混运具有明显优势,对露天矿车流规划具有评价和指导价值.

Abstract: According to the match of hauling fleet and materials, the truck hauling of open-pit was divided into three types: integrated fleet haulage, independent fleet haulage and combined fleet haulage. The traffic flow characteristics of the most difficultly combined fleet haulage were analyzed, and the compatibility of both integrated fleet haulage and independent fleet haulage was considered, a traffic flow programming model was proposed to meet the various needs of matching material. The difference for the application of three models was discussed, and the computing steps and the method to improve computing speed were explained for the simplified model. The results not only showed the serviceability of the proposed model, but also proved that combined fleet haulage is more superiority in the situation where distance between ore-unloaded place and rock-loaded place or between rock-unloaded place and ore-loaded place is near. The model has practical value for evaluating and guiding traffic flow programming of open-pit mine.
