采空区防灭火实践应用研究

Practical Application of Fire Prevention and Extinguishing in Goaf

某矿A4011工作面采空区与下部煤层A3009回采工作面上下相邻,为了确保已采空区和正在回采工作面的安全,消除灾害隐患,在加强回采工作面有害气体监测的基础上,对A4011采空区实施密闭、注氮、均压等综合防灭火技术,确保A3009工作面正常回采及矿井安全生产。

The gob of A4011 working face is next to the lower A3009 coal winning face in a coal mine.In order to ensure the safety of the gob and the working face being mined out and eliminate the hidden danger of disaster,the comprehensive fire-fighting technology such as airtight, nitrogen injection and pressure equalizing was applied to the A4011 working face on the basis of strengthening the monitoring of harmful gas in the working face,to ensure the normal mining and safe production of the A3009 working face.
