急倾斜特厚煤层分层开采工作面防灭火技术研究现状及对策

Research Status and Countermeasures of Fire Prevention and Extinguishment Technology at Slice Mining Work Face of Steep-inclined and Extremely Thick Coal Seam

对国内外关于急倾斜特厚煤层分层开采工作面防灭火技术的研究现状进行了分析,并结合该类工作面煤自燃外在影响因素,提出相应的措施,得出只有采取综合的技术手段并进行合理利用,才能真正有效地防治该类工作面的煤炭自燃,这也是今后此类工作面防灭火工作的发展趋势。

Home and abroad research status of fire prevention and extinguishment technology at slice mining work face of steep-inclined and extremely thick coal seam is analyzed.Combining with external factors of working face spontaneous combustion,corresponding measures are proposed.Only adopting comprehensive technical means and using them reasonably,truly effective prevention and control the coal spontaneous combustion of such working face can be achieved,which is the development trend of fire prevention and extinguishment for such working face.
