摘　　要：下沟煤矿综放工作面所采煤层为易自燃煤层 ,通过对其ZF180 2及ZF180 4两个综放工作面的煤层自燃研究分析 ,得出下沟煤矿 90m长综放工作面采空区煤层自燃及其自燃危险分布规律 ,为综放工作面煤层自燃火灾的防治提供科学依据。The seam adopted longwall with top-coal caving in Xia-gou coal mine is easy to spontaneous combustion. Based on the analysis of spontaneous combustion in Face ZF1802 and Face 1804, the paper presents the distribution law of spontaneous combustion and the threatened zone in 90m long top-coal caving face with the suggestion of a scientific prevention foundation.
