今年初,南非兰德采矿和设备公司安装了第一套全规模冷却设备和风力运冰系统。由于向矿内运冰比运冷却水更能节省排水费用,所以冰冷却引起了人们的注意。目前,制冰费用较高,但这种方法对世界上较深的矿山还是经济的。预期到八十年代末,随着制冰工艺的发展,冰将广泛地用作新建和扩建矿山地面生产的冷却剂。 Earlier this year, South Rand Mining and Equipment Company installed the first full-scale cooling equipment and wind-powered ice system. Ice cooling has drawn people’s attention because it saves drainage costs more than transporting cooling water to the mine. At present, the cost of making ice is high, but this method is still economical for deeper mines in the world. It is expected that by the late 1980s, as the ice making process has evolved, ice will be widely used as a coolant for new and expanded mine ground production.
