Abstract: With the Pansan Coal Mine depth deepening, high-temperature working place pose a challenge to production safety and health of workers. According to Pansan Coalfield acquired geothermal datas, analysis of geothermal conditions found Pansan Coalfield have significant geothermal anomaly. Combining mathematical statistics and burial depth geothermal linear regression analysis showed geotherm had a certain regularity. Based on the regularity,the geological reasons of geothermal anomaly could be analysed. Finally ,the conclusions can provide a frame of reference for Pansan Coalfield's production.
