Comprehensive Treatment of 4th Coal Seam Outcrop Fire in Haibaoqing Patch of Baoding Digging in Panzhihua

According to the characteristic of the 4th coal seam outcrop fire and its difficulty of controlling in Haibaoqing patch of Baoding diggings in Panzhihua,we gave the priority to the colloid technique to prevent and put out the coal mine fire.At one time,when available methods were taken in the fire region,such as blowing up,separation,level up,etc.,the temperature of the bore and concentration of CO in fire region declined evidently,and the character of combustion disappeared.So this control technique was effective,which eliminated safety hidden trouble of fire,and protected the safety production of coal mine around.
