| 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. |
