高瓦斯综采工作面煤层自燃应急封闭技术

Emergency sealing technology of coal spontaneous combustion in fully mechanized mining face with high gas

如何在矿井个体条件下综合运用封闭技术,实现对危险区域快速且有效的隔绝,是防灭火工作中无法回避的课题。针对15116工作面受断层影响出现的煤层自燃现象,采取应急封闭防灭火方案。在封闭隐患区过程中综合运用"地面封堵+井下密闭"的数种封闭技术,快速有效地完成了封闭,保证了井下作业安全。

It is an unavoidable issue in fire prevention and extinguishing work that how to use the sealing technology to achieve rapid and effective isolation from the dangerous areas. The coal spontaneous combustion occurred in No. 15116 working face affected by faults. By applying several sealing techniques of ＂surface plugging ＋ underground sealing＂ in the process of sealing the hidden danger area, the sealing work was completed quickly and effectively, and the safety production was guaranteed.
