在近二十年,自“矿山巨人”的电动轮汽车问世和日臻完善以来,世界各国的工矿道路上,重型汽车运输得到了迅速的发展。当前,在一些发达的资本主义国的露天矿山,电动轮汽车几乎全部取代了准轨铁路运输。在我国的工矿道路上,重型汽车的比重也在日益增加,车型也愈来愈大。近年来,我国已制造了20吨、32吨60吨、以及100吨等矿用自卸汽车。此外,我国历年来还进口不少国外重型汽车,其中包括载重108.9吨的伟步(WABCO)一120C型电动轮汽车。这些重型汽车的制造和引进,对矿山公路路面提出了新的要求。
In the past two decades, since the advent and improvement of the electric wheel vehicles of the “Mining Giant”, the transportation of heavy vehicles has been rapidly developed in the mining routes of various countries in the world. At present, in some open-pit mines in developed capitalist countries, almost all electric wheel cars replace the standard rail transport. In China’s mining road, the proportion of heavy vehicles is also increasing, models are getting bigger and bigger. In recent years, China has manufactured 20 tons, 32 tons and 60 tons, and 100 tons of other mining dump trucks. In addition, China has also imported many foreign heavy vehicles over the years, including the 108.9-ton WABCO-120C electric wheel car. The manufacture and introduction of these heavy vehicles put forward new requirements on the road surface of mines.
