New Designing Idea of Centralized Cooling System for Coal Mine

On account of the heat injury situation and the actual mine conditions of Jining NO.2 coal mine,the paper suggests new designing ideas of regional centralized cold water cooling system.The idea is getting the low temperature cold water from cooling system and reducing the air temperature.The paper introduces operating principle of the system,arrangement and the solutions of discharge heat condensation.Through the comparative and analysis,the solution of indirect using mine gushing water as cooling water was chosen.
