Abstract: Ground temperature distribution characteristic of Dingji mining area was analyzed from ground temperature and its gradient, terrestrial heat flow value. the geological factors influencing ground temperature and its distribution was uncovered. Results showed that Dingji Mine was a mine with high ground temperature and heat disaster. Ground temperature increased with deep in vertical direction and was influenced by tectonic distinctly in horizontal direction. Influenced by thick loose seam,ground temperature of the mining area was higher. Ground temperature and its gradient of Panji anticline area,east of mining area was higher than adjacent sunk part. Maximum temperature occurred at axle of the anticline influenced by Magmatic intrusion. Intensive faults at east of mining area resulted in whole ground temperature of this area was higher. As a whole,it was distinct that the ground temperature of this area was controlled by tectonic.
