  Abstract

The working environment is deteriorated due to a rise in temperature of a coal mine caused by increase of its depth and carriage tunnels. To improve the environment, the temperature distribution resulted by using the fan type ventilation system aiming for the temperature drop is calculated by using a fluid dynamic analysis program. The analysis shows that A coal mine needs 6,152 m3 min-1 for in-flow ventilation rate but the total input air flowrate is 4,710 m3 min-1, 1,442 m3 min-1 of in-flow ventilation rate shortage and the temperature between the carriage tunnel openings and the workings with exhausting ventilation system type is 2~3 ℃ less than that with blowing ventilation system type. The exhausting ventilation system type would be more effective than blowing ventilation system when the distance between the carriage tunnel openings and the workings is relatively far.
