摘要：
Zhujixi coal mine is a typical large mine characterized with large mining depth, high ground temperature, large heat dissipation from electromechanical equipment and serious heat damage. This paper takes Zhujixi coal mine as an example and puts forward ground two-stage refrigeration, large temperature difference to supply cooling as well as the adoption of high-low pressure heat exchanger to overcome high hydrostatic pressure. Those solutions solve the problem of difficult heat removal in high temperature mine and of high hydrostatic pressure in large mining depth mine. In addition, it suggests applying domestic equipment to underground cooling from the point of economic benefits.
