本文通过对霍林河南露天矿采用的单斗─—汽车工艺长期观测，对采掘工作面卡车不同站立位置进行对比分析，找出了最佳装车位置，进而对主采设备作业效率进行分析计算。为压缩车、铲一次作业循环时间，提高生产效率开辟了新的途径。
Through the long-term observation of the single bucket ── automobile technology used in Huolinhe South Open-pit Mine, this paper compares and analyzes the different standing positions of trucks on the working face and finds out the best loading position, and then analyzes and calculates the working efficiency of main mining equipment . For the compression car, shovel a cycle time, improve production efficiency opened up a new way.
