综放开采回采巷道喷射砼防火技术研究
Study on taking shotcrete precautions against gateway fire in fully mechanized mining with sublevel caving
【摘要】 根据煤层巷道自然发火的特点 ,研究了喷射砼在易自燃发火煤层综放开采回采巷道防火原理 ,并在现场进行了工业性试验 .实践证明 :喷射砼可以有效地预防巷道自燃火灾 ,这一技术在义马矿区得到了推广应用
【Abstract】 According to the characteristic of gateway coal seam spontaneous combustion, the principle of taking shotcrete precautions against gateway fire is studied, which coal seam prone to spontaneous combustion is mined with fully mechanized sublevel caving. Then industrial test in_situ is carried out. The method may validly prevent gateway five of coal spontaneous combustion. Finally, this technology has been adopted by Yima Coal Group.
