Numerical Analysis of Air-conditioning Cooling Effect in Working Face |
|
| Abstract: | To counter the heat hazard in 1302 working face of Tangkou Coal Mine,numerical simulation was carried out distribution law of air-flow temperature field according to the theoretical analysis and actual measurement at the site,the variation law of air-flow temperature in the working face with the supplied air temperature was obtained,and analysis was made on the cooling effect after using ice-cooling air-conditioning system.The results indicated that the temperature in the coal face was reduced 4~6 degree on average after suing air conditioning for cooling. |
