摘要
为降低煤层自燃影响工作面回采,本文以3102工作面回采为工程背景,根据工作面生产特点,通过制定工作面正常回采期间、过断层期间、窄煤柱以及邻近采空区等防灭火技术方案,实现了煤层自燃的针对性防治,确保了工作面回采期间安全。研究成果为其他类似矿井易自燃煤层开采期间防灭火工作开展提供了经验借鉴。
To reduce the impact of spontaneous combustion of coal seam on stoping of working faces,with stoping of the 3102 working face as the background and according to production characteristics of working faces,this paper formulates fire prevention schemes for working faces during normal stoping and fault crossing,narrow coal pillars and adjacent mined-out areas in order to fulfill targeted prevention and control of spontaneous combustion of coal seam and ensure safety during working face stoping.The study serves as a reference for fire prevention work during mining of other similar coal seams inclined to spontaneous combustion.
