摘要
针对刘庄煤矿151302工作面封闭期间的自燃现状,分析了综采工作面自燃发火的原因,结合综采面封闭后的气体分析数据和温度变化趋势,提出综合灭火技术措施,结果表明,采用综合灭火措施后,采空区内CO浓度和温度都有明显降低,有效的避免了火区的进一步扩大和恶化,保证了煤矿的安全生产。
In view of the spontaneous combustion of Liuzhuang Coal Mine 151302 working surface in seal period,this thesis analyzed the reason of the spontaneous combustion of fully mechanized working face and proposed the fire-fighting synthesis measure according to the actual situation,combining with the unit-closed gas analysis data and changes in the temperature trend.The result indicated that CO and temperature of fully mechanized face is obviously decreased after employed the synthesis measure,thus avoiding further expansion and deterioration in fire zone and ensuring the safety production in coal mine.
