Fire Prevention and Extinguishing Technology for Inflammable Thick Seam Fully Mechanized Caving Face During Dismantling Supports

The fire-proof work of dismantling supports is difficult in inflammable thick seam super-length fully-mechanized caving face, Qinggangping Coal Mine adopts three fire lines to prevent spontaneous combustion during dismantling support in fully mechanized caving face. This paper analyzes easy spontaneous combustion location during dismantling support, introduces the fire-proof principle, method and effect of three fire lines.
