如果露天矿的运输道路条件恶劣,运输汽车队的生产效率就低,而且运输费用也高。相反,如果露天矿的运输道路维护得好,运输汽车的运输效率就高,完成等量的生产任务就可减少汽车台数,还可减少设备投资和运输费用,对大量投资可迅速返本。因道路平整使滚动阻力那怕稍有减少,就可 If opencast mines have poor haul road conditions, TEUs are less efficient and costly to transport. On the contrary, if the open-pit mine’s transportation road is maintained well, the transportation efficiency of transportation vehicles will be high, and the same number of production tasks can reduce the number of vehicles, as well as the equipment investment and transportation costs, and promptly return large amounts of investment. Due to the formation of the road rolling resistance even slightly reduced, you can
