大家知道,运输工序是露天开采工艺过程中主要的和最繁重的一个环节。现在露天矿有大约一半的机械设备是运输设备;企业中近45％的职工从事运输作业;在总成本中运输费用占55％。由此可以看出改善露天矿运输的重要性,它是提高采掘工业中露天开采劳动生产率的决定性环节。露天矿运输工作的独特性表现在运输设备的选择,结构改进的方向和速度。 As we all know, the transportation process is the main and most heavy link in the open pit mining process. Today, about half of the open-pit mines are transportation equipment; nearly 45% of workers in the business are engaged in transportation operations; transportation costs account for 55% of the total costs. From this it can be seen that the importance of improving the transport of surface mines is a decisive factor in improving the productivity of open pit mining in the extractive industries. The uniqueness of open pit transport is reflected in the choice of transport equipment, the direction and speed of structural improvement.
