| Abstract: | In view of the CO leakage in the 8820 and 8822 goafs of 12#coal seams in Yungang Mine,the coal ash is used to fill the goafs,the board wall is constructed to fill the coal ash,and the marlisan is injected around the wall to block the leakage;the ground loess is grouted with grouting pump to put out the fire in the goaf.Through the comprehensive treatment of spontaneous combustion in the good results have been achieved and the hidden danger of spontaneous combustion has been eliminated. |
