| Abstract: | According to the wide area, large roof falling space, mine fire and gas existing, serious air leakage at the surface of the special large firing area in Baijigou Mine, the gas explosion control technology with water to seal the air coming roadway, the mine fire extinguishing technology with the surface boreholes filling high quantity of three phase foam and the fire extinguishing and gas explosion control technology with large quantity of nitrogen gas were adopted to completely put off and seal a firing area with an area of 10 million m^2. All above have prevented the gas re-explosion, fully recovered the mine production and obtained obvious economic and social benefits. |
