According to the feature of coal column spontaneous combustion in deep mining,basing on potential energy measurement,this paper analyzed the potential energy distribution and the status of gob.Coal spontaneous combustion was effectively prevented due to some comprehensive measures including: full-sectional guniting,grouting to consolidate the narrow coal pillars,injecting inhibition for fire prevention.Through the above comprehensive measures,coal spontaneous combustion was effectively prevented and the roadway was achieved.The study results give a beneficial guide to other analogical coal pillar safely.
