采空区“三带”测定在8214综放面的实践应用

Practical Application of "Three Zones" Determination in Goaf in 8214 Fully Mechanized Top Coal Caving Face

本文通过同煤集团燕子山矿8214综放工作面埋设采空区束管和热敏探头的方法测定采空区温度、O2浓度等变化,根据采空区埋设束管及温度探头,结合采空区"三带"的数学模型解算,利用综合方法划分出8214工作面采空区水平"三带"的范围,并总结提出了测定划分采空区"三带"时的注意事项。

In this paper, the temperature and oxygen concentration of goaf are measured by the method of burying bundle tube and heat sensitive probe in 8214 fully mechanized caving face of Yanzishan Coal Mine of Datong Coal Mine Group. According to the buried bundle tube and temperature probe in goaf and the mathematical model of "three zones" in goaf, the range of "three zones" of goaf level in 8214 working face is divided by comprehensive method, and the points for attention in determining and dividing the "three zones" of goaf are summarized and put forward.
