从排土场排弃环节入手，按照实测数据，分析自卸卡车排卸距离对推土机排弃费用的影响。分析了影响这一环节的因素．并推导出推上机排弃的单位成本与排弃距离的函数关系。依据计划剥离量，利用这一函数关系来核定推土机排弃的单位成本以及核定推土机的出动台数。加强工艺环节的密切配合，提高司机的操作水平，降低推土机的排弃费用，提高经济效益。 According to the measured data, the influence of dumping distance of dump truck on the abandonment cost of bulldozer is analyzed. Analysis of the factors that affect this link. And deduce the unit cost of pushing on the machine and the function of the distance to abandon. According to the planned amount of stripping, use this function to verify the unit cost of bulldozer abandonment and the number of approved bulldozers. Strengthen the close cooperation of the process, improve the driver’s operating level, reduce the abandonment costs of bulldozers, improve economic efficiency.
