Centralized Cooling System in Yangcheng Coal Mine

In order to relieve the underground heat harm problems of coal mine, we systematically study and set up a centralized cooling system and study and design several subsystems in detail. We developed ZLS3300/10000 underground centralized refrigeration units, successfully combined ground power plant “re-circulating cooling water system” and underground centralized cooling “circulating cooling water system” effectively, which simplified the process of the system and reduced the engineering investment.
