Abstract

According to the cross-section layout of Kongzhuang Coal Mine shaft and mine production conditions, the paper summarized and analyzed the systems of slice ice cooling, the thermo-power glycol cooling, HEMS underground centralized cooling, and vacuum ice cooling. From the effect, investment, cooling system operating stability, thermal transportation pipe installation, quality of water, discharge of heat underground, and other comprehensive consideration of the centralized cooling plan, the suitable way of cooling the mine is only the vacuum ice cooling scheme. Meanwhile, through implementation of the project, it will fill a centralized cooling technology gap in ice making technology, ice transportation pipes, ice transportation process, pressurized air cooling, underground ice melting technology, and energy-saving technology in ice making, which is a great breakthrough in our coal mines.
