Analysis on High Temperature Airflow Heat Source and Prevention Measures in Guqiao Coal Mine

To the problem of high temperature airflow in deep mining,this paper carried on the omni-directional analysis to high temperature heat source in Guqiao coal mine with representativeness.Relative high temperature control measures were put forward,which included mining technical measures and the cooling system.The cooling system of partition concentrated refrigeration and condensing heat ground emissions were introduced in detail,and the comparative analysis of the effect of cooling measures was made.The results show that taking cooling measures can reduce the temperature of the local area in underground about 4 ~ 5℃,which improves working conditions,enhances work efficiency,reduces the accident rate,guarantees the safety production in coal mine.
