Incombinationwiththecertainconditions,adeepmineheatdisastercon鄄 trol plan suitable toNo郾4 Minewasprovidedandtheplanwouldapplythewatersprayinginthemineshaftasthedisposableheatreleasing with water for the local refrigeration and temperature reduction plan. The paper introduced theworking principle,equipment applied and operation condition of the mine temperature reduction system. The paper had a study and analysis on the temperature reduction effect of the deep mine temperature reduction system. The results showed that the temperature of the coal mining face could be reduced by6 to 8 益 and the max temperature of thecoal miningfacecouldbecontrolledat25 to27 益. Thusthe systemwouldbebeneficialtoreducethe temperature at the mine roadway heading faces in China and to eliminate the mine heat disaster. Key
