利用多用途设备,可以经济地开采小矿床,这些小矿床用其它方法开采将是不经济的。瑞典和在其它矿业国家一样,实现机械化有助于提高生产率,降低成本。许多矿山已经采用了先进和高效的采掘设备、精心设计和现代采矿方法。但对较小的矿山,这样做未必总是可行的;有时矿体太小,不值得投资建矿和购买昂贵设备。 With multi-purpose equipment, small deposits can be economically mined, and the extraction of these small deposits by other means would be uneconomical. As in other mining countries, mechanization helps to increase productivity and reduce costs. Many mines have adopted advanced and efficient extractive equipment, well-designed and modern mining methods. But for smaller mines, this may not always be feasible; sometimes the ore body is too small to invest in mining and expensive equipment.
