摘要
为了防止徐州张双楼煤矿9421综采工作面回撤期间采空区煤炭自燃,采用了均压防火、注高水材料防火、注液态CO2防火和灌注普瑞特防火等防灭火控制技术,有效控制了采空区煤炭氧化趋势,确保了工作面的安全生产。
In order to prevent 9421 fully mechanized coal working face goal coal spontaneous combustion during the retreat in the Zhangshuanglou coal mine of Xuzhou, it adopts many kinds of fire prevention control technologies such as pressure fire prevention, high moisture material injection fire prevention, liquid CO2 injection fire prevention and perfusion Pratt fire prevention. It effectively controls the trend of the goal coal oxidation to ensure the safety production of working face.
