采矿业是国民经济的一个重要基础产业。我国矿山开发自建国以来有了长足的发展,矿产品产量迅速增长。1990年,我国原煤、生铁等十种有色金属产量分达到10.8亿吨、1.38亿吨、6238万吨;原煤、原油、原铁产量分别比1949年增长了32.75倍、1151.58倍和249.5倍。但我国目前矿山绝大多数为独立矿山,地处边远,设备陈旧,产品单一,资金投入严重不足,一旦资源枯竭,将陷入窘境。如何使矿山转产脱困,摆脱目前
Mining industry is an important basic industry of national economy. Since the founding of the PRC, mine development has made great strides, with the output of mineral products increasing rapidly. In 1990, the output of 10 non-ferrous metals such as raw coal and pig iron in our country reached 1.08 billion tons, 138 million tons and 62.38 million tons respectively; the output of crude coal, crude oil and crude iron increased by 32.75 times, 1151.58 times and 249.5 times respectively over that of 1949.
