摘　　要：通过治理宁夏白芨沟煤矿特大型火区,研究开发了远距离水封抑爆、地面灭火钻孔快速施工、地面大流量注三相泡沫、大流量注氮抑爆和惰化火区、高瓦斯火区水封巷道的锁风启封、氮气喷雾降温、均压启封火区及防复燃等一整套治理高瓦斯矿井特大火区的技术.应用这些技术抑制了白芨沟煤矿特大火区内瓦斯的再爆炸,扑灭并安全启封了该火区,在救灾和恢复生产过程中确保了安全.During the extinguishment of an extraordinary mine fire in Baijigou coal mine, a series of new technologies were developed. These technologies include remote water sealing to suppress explosion, fast construction of boreholes, massy injection of three-phase foam, massy infusion of nitrogen to suppress explosion, unsealing of highly-gassy and watered tunnel with air locked, cooling with water-sprayed nitrogen, unseal of fire zone with pressure balanced, prevention of after-combustion, etc. The methane in the fire zone stopped explosion using these technologies, and the fire was totally extinguished. Moreover, these technologies ensured the safety of rescue and production-recovery work.
