高瓦斯易燃煤层自燃发火原因分析及防治

摘要

针对厚煤层开采比重加大，且伴随采空区遗留浮煤，回采工作面漏风等因素致使煤层自燃发火频繁，矿井安全生产形势日趋严峻的问题，分析了煤体自燃发火原因，加强自燃发火预测，采取有效的防灭火技术及装备，确保易燃煤层安全高效开采势在必行。%Increased proportion of thick seam mining, with other factors, including float coal left behind in mined-out areas and air leak in caving face, causes more frequent spontaneous combustion, which has become a worsening problem threatening the safe production in mines. The paper studies its causes and proposes the prediction for the spontaneous combustion and effective fire control techniques and equipment to ensure the safe and efficient mining in the inflammable seams.
