采煤工作面采空区自燃“三带”分布实测研究

Measurement and Study on "Three Belts" Distribution of Spontaneous Combustion in Goaf of Coal Face

为了研究采空区自燃“三带”分布规律,防止采空区自然发火的发生,以山西汾西瑞泰井矿正珠煤业有限公司11502工作面为研究背景,通过现场数据监测,对测定数据和结果进行科学理论分析,采用氧浓度和温度的双重指标分析采空区自燃“三带”,并采取针对性措施,可有效防止自然发火的现象发生。

In order to study the distribution law of spontaneous combustion"three zones"in goaf and prevent the occurrence of spontaneous combustion in goaf,the paper takes the 1502 working face of Shanxi Fenxi Ruitai Mine Zhengzhu Coal Industry Co.,Ltd.as the research background,through on-site data monitoring,the measured data and results are analyzed scientifically and theoretically,and the double index analysis of oxygen concentration and temperature is adopted.The"three zones"of spontaneous combustion in goaf and the corresponding measures can effectively prevent the occurrence of spontaneous combustion.
