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。
為確保鹿窪煤礦2307(2)綜放工作麵採空區自燃防治做到科學、閤理、經濟、有效,對2307(2)綜放工作麵開採期間採空區自燃“三帶”分佈規律進行瞭測定與分析;得到瞭採空區自燃氧化“三帶”的範圍,確定瞭基于煤炭自燃防治的最小安全推進速度。對2307(2)採空區自燃“三帶”分佈規律的研究可以有效指導工作麵的安全生產,杜絕自然髮火事故的髮生。

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"three zones"distribution;determined the safety range of gob spontaneous combustion"three zones", and determined the minimum safety based on coal spontaneous combustion prevention and control of advance speed. In research the distribution laws of spontaneous combustion"three zones"of 2307 (2) in can effectively guide the safety production of working face, to prevent spontaneous combustion accidents.
