露天矿的生产技术条件日趋复杂,其中包括采场深度增加、矿岩提升高度增加和运输距离增加,这是露天铁矿汽车运输工艺发展的特征。此时,提升高度的增加比运输距离的增加更迅速,从而使自卸汽车在联合运输系统中主要成为集运环节(图1)。当自卸汽车的主体部件和机组的可靠性进一步得到改善时,提高露天矿汽车运输技术经济指标和 The technical conditions for the production of open-pit mines are becoming more and more complicated. Including the increase of stope depth, the increase of ore rock height and the increase of transportation distance, this is the characteristic of the development of the open-pit iron ore vehicle transportation process. At this point, the increase in lift height is faster than the increase in travel distance, resulting in the Dump Truck becoming the predominant part of the combined transport system (Figure 1). When the dump truck’s main components and units to further improve the reliability of the open-pit mine to improve technical and economic indicators and
