三十年来,虽然我国发电量有了很大增长,但仍不能满足日益发展的生产的需要。因此,节约电能是我国长期的一项政策。与其它企业一样,我国矿山节电潜力是很大的。根据规模及开采方式不同,采选企业平均每吨矿石(有色金属)的耗电量约为30～70度,大型企业低于小企业,露天开采低于坑下开采。因此,一个中等规模的企业要每年节电几百万度是完全可能的。现从矿山供电系统方面来讨论其节电的
In the past 30 years, although the power generation in our country has greatly increased, it still can not meet the needs of the increasingly developed production. Therefore, saving electricity is a long-term policy of our country. Like other enterprises, the potential of electricity saving in our country is great. Depending on the scale and mode of exploitation, the average power consumption per tonne of ore (non-ferrous metals) in mining and dressing enterprises is about 30-70 degrees. Large enterprises are lower than small ones and open mining is lower than that under pit. Therefore, it is entirely possible for a medium-sized enterprise to save several million degrees of electricity annually. Now from the mine power supply system to discuss its energy-saving
