【摘要】：三河尖煤矿72205工作面回撤液压支架期间,工作面及回风巷道内CO浓度严重超限,根据该工作面围岩地质条件,分析了自然发火原因,并阐述了自然发火的经过。在采用常规防灭火方法效果不理想的情况下,通过应用普瑞特防灭火新技术成功快速地扑灭火区。
[Abstract]:During the withdrawal of hydraulic support in 72205 face of Sanhejian Coal Mine, the CO concentration in the working face and the return air roadway was seriously exceeded. According to the geological conditions of surrounding rock of the working face, the causes of spontaneous combustion were analyzed, and the process of spontaneous combustion was expounded. Under the condition that the effect of conventional fire prevention and fire extinguishing method is not satisfactory, the fire zone is extinguished quickly and successfully by using the new technology of fire prevention and fire extinguishing by Prette.
