地下矿用铲运机多以柴油机驱动,但数年前又出现了可以替代它的电力驱动。由于出现了此项需求和对这方面的兴趣日益增长,MAN-GHH公司于1975年开始研制以卷筒电缆供电的电动铲运机。首批这种铲运机供给了意大利的一个矿山,后来,该矿在生产中全部改用了GHH电动铲运机。地下矿用铲运机通常是在冲击载荷、尘埃多、潮湿和高温的环境中作业。开采不同矿物时一些较重要的环境影响如表1。 Underground mine scrapers are mostly powered by diesel engines, but a few years ago there was an electric drive that could replace it. As a result of this demand and growing interest in this area, MAN-GHH started the development of a cable-powered electric scraper in 1975. The first of these scrapers supplied a mine in Italy, and later the mine was converted to a GHH electric scraper in production. Underground mining scrapers are usually operated in impact loads, dusty, humid and hot environments. Some of the more important environmental impacts of mining different minerals are shown in Table 1.
