Abstract: With the increase of mining depth, the coal mine heat damage problems due to rising ground temperatures had become increasingly prominent. The exploitation depth of west wing mining area reached 700 m in Jining No.3 Coal Mine, mine heat damage occurred mainly in summer and heat damage was not obvious in winter, the seasonal feature of heat damage showed that the ground climate impacted underground climate significantly. It monitored the coal mine thermal environment automatically and dynamically, focused on analyzing the impact law and factors of ground climate for underground climate and mine thermal environment.
