双鸭山矿务局选煤厂新矸石山投入使用后6年便开始自燃。先后采用了挖掘浇水、卤素阻燃剂浇注、推土机翻开用水浇、黄泥封闭及高压喷射阻燃剂等多种灭火方法,经3年的治理,矸石山的自燃不但没有减弱,反而有加速趋势。燃烧面积达4500m~2,矸石山表面出现了大片明烟明火区,并伴有硫磺晶体析出,燃烧所产生的大量二氧化硫及烟雾严重污染了市区的环境。后来采用以深部注浆法为主的灭火方法,最终将矸石山自燃彻底扑灭。
Shuangyashan Mining Bureau coal preparation plant waste gangue put into use six years after it began spontaneous combustion. Has adopted the excavation of water, halogen flame retardant pouring, bulldozer turned open water pouring, yellow mud closed and high pressure jetting fire retardants and other fire fighting methods, after 3 years of governance, spontaneous combustion gangue not only did not diminish, but there is Accelerate the trend. Burning area of 4500m ~ 2, appeared on the surface of the gangue smoke bright fire zone, and accompanied by precipitation of sulfur crystals, burning a lot of sulfur dioxide and smoke seriously polluted the urban environment. Later, the use of deep-grouting method of fire-fighting method, the final spontaneous waste gangue completely extinguished.
