The wide coal pillar (60 m) near the edge of empty cave, forming leaking air roadway with residual drill holes of inlet roadway and drainage holes of total return air roadway, under the effect of strong ventilation negative pressure in the return air roadway, after more than a year of slow oxidation, caused spontaneous combustion of coal seam near the edge of the collapse column. The technical measures, construction technology and fire extinguishing equipment for the combination of borehole grouting covering plugging, air tunnel fissure plugging (grouting) and local air regulation were introduced, the high temperature point in the coal pillar was gradually reduced to the normal ambient temperature, and various fire extinguishing technical objectives were achieved, which provided a scientific, reasonable, safe, efficient, economical and inexpensive prevention and control method for fire areas under similar geological conditions.
