Abstract: From influence factors of coal mine heat disaster, the cooling load calculation method of coal mine was studied, the local temperature control technology was proposed. ZLS-90 movable cooling equipment was developed successfully, and the enthalpy difference comprehensive testing system was used to test the performance of this equipment. It was also proposed that the heat transfer technology was used to deal with the mine condensing heat and comprehensive utilization by using heat-rod. By means of local temperature control technology, the effective cooling was carried out for heat disaster mine, it guaranteed the working environment under coal mine, and ensured the coal mine safety production. It achieved high efficiency, conservation and environmental protection for resource.
