Abstract：Zhujixi coal mine is a typical large mine characterized with large mining depth , high ground tem-perature , 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 hy-drostatic pressure in large mining depth mine.In addition , it suggests applying domestic equipment to under-ground cooling from the point of economic benefits.
