本文選題：油氣火災(zāi)　切入點(diǎn)：液氮抑爆　出處：《煤礦安全》2015年08期

【摘要】：海石灣煤礦6112工作面采空區(qū)自然發(fā)火,引燃了上部油砂巖下泄到采空區(qū)的油氣,迅速擴(kuò)大為全礦大火。礦井采用注大流量氣氮、液氮和二氧化碳的方法,抑制了瓦斯爆炸,安全封閉了全礦6個(gè)井口,并采用縮封技術(shù)和大流量高壓水槍降溫技術(shù),將火區(qū)從井口縮封到工作面,采用消火道鉆孔注漿滅火技術(shù)徹底撲滅了火源。介紹了搶險(xiǎn)救災(zāi)過(guò)程中的抑爆封閉技術(shù)、縮封技術(shù)、消火道滅火技術(shù)及滅火效果。
[Abstract]:The spontaneous combustion of goaf in 6112 face of Haishiwan Coal Mine ignited the oil and gas released from the upper oil sandstone to the goaf and rapidly expanded into the whole mine fire.The mine adopts the method of injecting large flow of gas, nitrogen, liquid nitrogen and carbon dioxide to restrain the gas explosion, and safely seals the whole mine's 6 wellheads, and uses the technology of shrinking sealing and high pressure water gun cooling technology to seal the fire area from the wellhead to the working face.The fire source was completely extinguished by means of fire extinguishing by drilling and grouting fire extinguishing technology.This paper introduces the explosion suppression and sealing technology, the shrinkage sealing technology, the fire extinguishing technology and the fire extinguishing effect in the course of emergency rescue and relief.
