深井开采矿山人工制冷技术综述

摘要

As the increasing of mining depth, sometimes the natural ventilation and cooling can't meet the demand of aeration-cooling. The ordinary air conditioning technique is applied in deep mining and the shaft air-conditioning systems appear. The paper introduces the underground central air-conditioning system, ground central air-conditioning system, ground-underground combining air-conditioning system, dispersed local air-conditioning system.Meanwhile, the shaft air-conditioners with water or ice as refrigerant are introduced respectively. It is put forward that ground central air-conditioning system is the developing trend of deep shaft cooling.%深井开采矿山随着开采深度的不断加深单凭自然通风降温有时已经不能满足通风降温的需要,为此人们把常规的空调技术发展应用到深井开采当中而出现了矿井空调系统.介绍了井下集中空调系统、地面集中空调系统、井上下联合空调系统和井下分散局部空调系统以及以水为载冷剂的矿井空调和以冰为载冷剂的矿井空调等.提出地面集中制冷站矿井空调系统是深井开采降温的发展趋势.
