摘要
Abstract
Xinjiang Wudong Coal Mine +5754501 working face has the problems of a small kiln mining history,spontaneous combustion in overlying old area,and the open fire area in exposed coal seam during the pressure relief of surface roof.For the special mining conditions existing in +5754501 working face,the comprehensive fire preventing and extinguishing technology measures such as pressure equalization ventilation,advanced nitrogen injection and nitrogen injection,and effectively prevent the spontaneous combustion and re-ignition in open fire areas in mining areas of the small kiln,overlying old empty area,goaf and the original surface.关键词
