综放工作面防灭火注氮技术研究

Fire-fighting nitrogen injection technology research of full-mechanized caving mining face

针对综放工作面在开采过程中由于遗煤较多,工作面漏风大,导致采空区遗煤易自燃,给工作面的安全高效的开采带来隐患,为了有效地避免综放工作面遗煤自燃,本文以官地矿28412综放工作面为研究对象,通过采用工作面运输顺槽埋管注氮工艺,有效地抑制遗煤氧化,为以后的综放工作面安全高效的开采提供一定的依据。

For fully-mechanized caving is more, because of the heritage in the process of mining coal face air leakage is big, cause the traces of goaf coal spontaneous combustion, brings to the safe and efficient mining working face in hidden trouble, in order to effectively avoid caving mining working face of coal spontaneous combustion, based on the geological mining 28412 as the research object of full-mechanized caving mining face, by means of working face buried pipes transport gateway nitrogen injection process, effectively restrain heritage of coal oxidation, after for safe and efficient mining of fully-mechanized sublevel caving mining working face is to provide a certain basis.
