摘要
分析了大黄山矿高瓦斯大倾角煤层综放面采空区火灾的特点和治理难度,采用同位素测氡法探测了火区范围,然后通过地面灌浆系统向火区灌浆,同时通过钻孔向火区压注凝胶及复合胶体等,对综放面采空区火灾进行了有效的治理,确保了工作面的顺利启封并恢复生产,产生了显著的经济和社会效益。
The characteristics and difficulty of the fire which happend in high gas and big obliquity coal seam of the DaHuangShan mine were and yzed. The radon measuring technique to detect fire area scope. Then the syrup were infused toward the fire area through a ground infuse syrup system. In the meantime, note gel and compound gel were pressed through the drill. The empty area was carried on effectively managmont. A condition for opening the working face and resumly production was created and visible economy and society benefit were obtained.
