千米深井防灭火技术研究与应用

Research and Application of Fire Prevention Technology in Kilometers Deep Well

根据古城煤矿的自然发火特点,分析了不同地点、不同条件的自然发火原因,采取了调整通风系统、注氮、压注防火材料、封堵进回风隅角等综合防灭火措施,取得了良好的效果,并为以后自然发火防治提供了技术依据。该技术对防治大采深、强冲击、高地压、高地温煤炭自然发火具有较好的指导作用。

In view of the spontaneous combustion characteristics of Gucheng coal mine, the paper analyzed the different location, different conditions of spontaneous combustion, adopted many comprehensive fire prevention measures such as adjusting the ventilation system, nitrogen injection, injection freproofng materials and blocking off the return air corner, etc, which has obtained very good effect, and provide the technical basis for prevention and control of spontaneous combustion. The technology has a good guiding role in the prevention and control of large mining depth, strong impact, high ground pressure and high ground temperature coal spontaneous combustion.
