火区调压技术在煤峪口矿的实际应用

Practical Application of Pressure Regulating Technique in Burning Section of Meiyukou Coal Mine

在采场均压防灭火实验室模型模拟实验的基础上 ,总结了煤峪口矿现场实施火区的调压工艺技术。该技术包括利用调压气室平衡火区风压、提高工作面风压和堵塞地表裂隙 3项调压措施 ,其防灭火效果十分显著。在这 3项措施中 ,无论是工作面升压或气室调压失效 。

Based on the simulated laboratory experiment of pressure balance for fire extinguishing, the pressure regulating technique in the burning section of Meiyukou coal mine is summarized. Three pressure regulating measures, namely the application of pressure regulating air chamber to balance the air pressure of burning section, increasing the air pressure of the working face, and filling the surface crannies, are very effective in preventing and extinguishing the fire. Among these three measures, notwithstanding the pressure regulation for the working face or the air chamber pressure regulation failed, the measure of filling the surface crannies will play a very important role.
