【摘要】 以晓南矿707综采面实际情况,分析了易自燃煤层煤巷(高顶、高冒处及巷间煤柱)自燃产生的原因和特点,介绍了对煤巷高顶处,采用调风、导风等技术措施防止自燃的发生和蔓延,对巷道间煤柱则采取包帮、充填、压注凝胶等技术措施延缓和阻止了煤柱的自然,为矿井的安全生产,提供了易自燃厚煤层防治煤巷自燃技术措施。更多还原

【Abstract】 According to the practical situation of fully-mechanized coal mining working-face 707, the reasons and characteristics, resulting from spontaneous combustion, are analyzed for spontaneously combustible coal seam (pillar of high roof, roof-caving and between roadways). The technical measurements, by applying airflow-adjusting and airflow-leading, are introduced to prevent the spontaneous combustion from happening and spreading for high roof of coal roadway. For pillars between roadways, the technical measurements are applied wall-packing, filling and jell-injecting to prevent the spontaneous combustion of pillar. And the technical measurements are put forward to prevent and control the spontaneous combustion of coal roadway of combustible thick coal seam for safety production of mines.更多还原
