Practical research on high-temperature heat-harm prevention and control technology by stages in Chenmanzhuang mine

According to research of high-temperature heat-harm in different stages of Chen Manzhuang coal mine, the different stages of the cooling treatment solutions were put forward. The implement of drop-temperature technology creating a good and comfortable working environment, improving the production efficiency, promoting the safety in production. It provides reference for preventing heat-harm in coal mine with similar condition.
