摘要
神东煤炭公司补连塔煤矿22305工作面上覆煤层采空区因浮煤自燃,造成了大面积采空区火灾,通过对防灭火国内外研究现状的分析,确定了降温、降氧的防控措施,先后采取了灌注液态惰性气体、灌浆等措施对火区进行了全方位处理,最终CO等火区指标气体下降到可控范围,达到了安全开采的条件。
The float coal spontaneous combustion in Bulianta Coal Mine 22305 working face overlying coal gob area of Shendong coal company caused a large area gob fire. Based on the analysis of domestic and foreign research present situation of fire prevention, the paper determined control measures of the cooling and oxygen - consumed, and the comprehensive treatment for sealing fire area with perfusion of liquid inert gases, grouting and other measures were conducted. Eventually, fire zone index gas such as CO dropped to controllable range, and the safe working conditions was achieved.
