Abstract: In order to solve the difficult problems of the high spontaneous combustion danger of seam caused by the high ground tempera?ture of the coal mining in the deep depth mine，the paper had a study on the seam oxidation and thermal releasing features of the high ground temperature coal mining face and the pre－control method． Fourier transform infrared spectrometer and large spontaneous combustion experiment device were applied to test the high ground temperature affected to the active functional group and the spontaneous combustion period of the coal． A site observation was conducted on the spontaneous combustion danger area in the goaf of No． 2302 high ground tem?perature coal mining face in Longgu Mine． The study results showed that when the ground temperature was 42 ℃，the coal spontaneous combustion period would be reduced by 25 days than when the ground temperature was 20 ℃ ． The high ground temperature could make the coal surface active function group number and the intermediate active product value increased and the oxidation thermal releasing would be obviously increased． The oxidized temperature rising zone scope would be increased． According to the high ground temperature affected to the oxygen supply，thermal accumulation condition and the oxidation thermal releasing．The combined fire prevention method was put for?ward，including using leakage sealing and nitrogen injection to reduce the oxidation of the coal mass，using resist foam to resist coal，using liquid carbon dioxide pressurized injection and glue injection to inhibition coal temperature rising． With the site application to Juye Mining Area，the method could affectively control the coal spontaneous combustion in the goaf and high ground temperature coal mining face．
