摘要
为确保鹿洼煤矿综放工作面采空区自燃防治做到科学、合理、经济、有效,对该矿2307(2)综放工作面开采期间采空区自燃"三带"分布规律进行了测定与分析;确定了采空区自燃氧化"三带"的分布范围,以及基于煤炭自燃防治的最小安全推进速度。对该工作面采空区自燃"三带"分布规律的研究,可以有效指导工作面的安全生产,杜绝自然发火事故的发生。
In order to ensure the goaf spontaneous combustion prevention work of the full-mechanized caving working face in Luwa coal mine to be scientific, reasonable, economical and effective, through measuring and analyzing the spontaneous combustion 'three zone' distribution regularity during the mining period of the 2307(2) full-mechanized caving face, determined the distribution range of spontaneous combustion 'three zones' in goaf, and the minimum safety advancing speed based on the prevention and control of coal spontaneous combustion. The research on the spontaneous combustion'three zone' distribution regularity in goaf of full-mechanized caving face can effectively guide the work of the safe production, and prevent spontaneous combustion accidents.
