铁道运输在国外露天矿具有悠久的历史。虽然由于露天矿的开采深度逐渐增大,出现了各种联合运输代替了单一的铁道运输。但是由于铁道运输具有运量大,在一定条件下运费低等优点,现在仍占有重要地位。近些年来,国外露天矿铁道运输的技术有了很大的发展,其中机车车辆的发展更为突出。故本文就机车车辆的发展概况及新的技术成就简略介绍如下,供有关同志参考。
Open-pit railways in foreign countries have a long history of mining. Although various types of combined transport have taken the place of a single rail transport, due to the gradual increase in the mining depth of open-pit mines. However, due to the advantages of large amount of freight traffic and low freight rates under certain conditions, railway transport still occupies an important position now. In recent years, there has been a great development in the technology of railway transportation in the open-pit mines in the world, among which the development of rolling stock has become more prominent. Therefore, this article on the development of rolling stock and new technical achievements outlined below, for the comrades for reference.
