为了加快地下矿山建设速度，扩大开采规模，提高经济效益，我国有色、冶金、黄金和化工等系统的众多地下矿山采用了进口或国产铲运机共900余台进行采场出矿和掘进出碴。在所使用的铲运机中，有64％为进口产品，不仅价格昂贵，且因关键件未国产化，无备件来源，导致数百台报废。 In order to speed up the construction of underground mines, expand the scale of mining and improve economic efficiency, a large number of underground mines in China’s nonferrous metals, metallurgy, gold and chemical systems use imported or domestic scrapers a total of more than 900 units for stope out of ore and digging out of ballast . Of the scrapers used, 64% are imported products, which are not only expensive, but also are not scrapped due to the lack of domestically produced key parts, resulting in the scrapings of hundreds.
