| 摘 要： | 分析了一起特厚煤层沿巷道底板掘进巷道的钻场因进行顺层钻孔抽采导致煤层自燃事故的原因,提出了防治该类自燃发火隐患的技术措施：抽采钻孔抽入口必须位于巷道周围的破碎区以外;定期监测顺层抽采钻孔内气体变化情况;严格控制在巷道的冒落区、阶段煤柱内布置钻孔抽采瓦斯.

| Abstract: | This essay analyzes the problems of a self - ignite accident, which was caused by drilling extraction during digging into the tunnel drill fields in an especially thick coal seam. Furthermore, it puts forward a technique solution on how to prevent such kind of self- ignition, that is the entrance of the drill hole must locate out of the crash area of the tunnel, Periodically monitor the air changing in the drill hole, strictly control gas - adopting in tunnel emit fall area and the stage coal pillar. |
