高瓦斯易自燃煤层火区抑爆技术研究

Research Explosion Suppression Technology for High Gas and Combustible Coal Seam Fire Area

结合矿井自然发火位置规律、瓦斯爆炸理论和火区治理理论阐述了香源矿1203封闭采空区瓦斯爆炸事故的经过并分析原因,用爆炸三角形解释了爆炸过程,介绍了密闭和注入氮气的治理措施,最后对采取措施后的火区监测数据进行分析,火灾治理效果较好。

Expounds the accident and its cause of gas explosion at goaf in Xiangyuan coal 1203 basing on the regular pattern of location in mine spontaneous combustion,the gas explosion theory and fire area governance theory, explains the explosion process basing on explosive triangle,then introduce the treatment measures such as being airtight and nitrogen injection,at last,the monitoring data of managed fire district,and the governance effect is proved to be practical.
