摘要
近年来,随着煤炭开采力度的加大,矿井采空区自燃火灾频发。基于采空区煤自燃特点,分析了液态CO2防灭火技术对采空区的降温、惰化特性,研究了液态CO2防灭火技术工艺和装备。以平煤十二矿17060采空区自燃火区治理为例,通过在现场应用,取得了很好的效果。
In recent years,with increasing mining strength,spontaneous combustion frequently occurs in coal mine,this paper focused on the characteristics of coal spontaneous combustion in goaf.Then analyzed the fire prevention characteristics of liquid CO2.Also,the general feature of liquid CO2 Fire-fighting equipment will be studied.At last,through the liquid CO2 practical use in goaf 17060,the governance effect seems very well.
