摘要
为了解决中兴煤矿1207工作面采空区遗煤自燃无法熄灭这一难题,采用调整采空区注氮方案,改变采空区瓦斯抽采方案、调整通风设施、采空区注固体水材料等综合防灭火措施,使采空区CO浓度下降至安全范围,有效抑制了1207工作面采空区遗煤自燃。
In order to solve the spontaneous combustion of coal in goal can not be extinguished of Zhongxing coal mine 1207 working face, by adjusting the nitrogen injection in the goal, changing the goaf gas extraction scheme, adjusting the ventilation, goaf comprehensive fire prevention measures, such as solid water injection materials make goal CO concentration fell to a safe range, effectively restrain the traces of 1207 working face of coal spontaneous combustion.
