    • Abstract
  • According to the high temperature problems of Jining No.2 Mine, we present the method that takes advantage of the low temperature water storage in the eleventh mining area and combines the air cooler to reduce the temperature of the coal mine and achieve cool water cycle and avoid the water supply and drainage problem. After operating the cooling system in Jining No.2 Coal Mine, we carry out test and contrastive analysis on the thermodynamic parameters of airflow at working face before and after cooling. The results showed that the average temperature of dry bulb of working face decreased 2.2 ℃ and the average temperate of wet bulb of working face decreased 2.6 ℃, which achieved good application effect.
