Abstract: Because of the problems of heat damage of Huainan coal field, we analysis the mechanism of ground temperature from the geological conditions and mining depth. It is concluded the distributing rules of ground temperature and the influence of the main factors in ground temperature anomaly. According to the big mining depth,high yield and high temperature of the Huainan coal mine, we summarize the control methods of ground temperature anomaly and then introduce the advantage of cooling system and the cooling effect.
