Abstract
With the rapid development of coal mine resources, heat harm in deep mine is one of the key problems to be solved in our country. In this article, through analyzing the different heat sources of the mine,we get the calculation model of airflow temperature which is related to the different feature points of shaft , horizontal and slant roadways and extraction working areas.We also take the actual geological conditions into consideration and build simulation system in coal mine to imitate and budget the airflow temperature and air amount in roadway which is at different ventilation system conditions. And it can provide theoretical and technical basis for the optimization scheme research of mine ventilation system , the ways to choose the mine refrigeration system and installation position of air cooler.
