摘要
为确保鹿洼煤矿2307(2)综放工作面采空区自燃防治做到科学、合理、经济、有效,对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;得到了采空区自燃氧化"三带"的范围,确定了基于煤炭自燃防治的最小安全推进速度。对2307(2)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 deer hollow coal mine 2307 （2） the prevention and control of fully-mechanized caving gob’s spontaneous combustion do scientiifc, reasonable, economic and effective, we determined and analyzed during the fully-mechanized caving mining of 2307 （2） gob’s spontaneous combustion＆quot;three zones＆quot;distribution;determined the safety range of gob spontaneous combustion＆quot;three zones＆quot;, and determined the minimum safety based on coal spontaneous combustion prevention and control of advance speed. In research the distribution laws of spontaneous combustion＆quot;three zones＆quot;of 2307 （2） in can effectively guide the safety production of working face, to prevent spontaneous combustion accidents.
