Based on the abnormal ground temperature phenomenon in Qianjiaying Mine, through underground field temperature measurement data, drilling exploration phase temperature measurement data and comprehensive analysis of mine exploitation actual data, Qianjiaying mining field ground temperature distribution was shown. The result showed that Qianjiaying coalfield ground temperature increased with coal seam depth and the obvious ground temperature high value anomaly area appeared in northwest of the coalfield; the middle and west of the coalfield came by two abnormal temperature zone due to deep heat upwelling, without the feature of temperature going up with coal seam depth.
