摘要
为了预防石港煤矿15102工作面发生自然发火,对15102工作面易引起自燃的危险因素进行分析,并在14号煤层打顺层注浆钻孔,注入MEA高分子阻化泡沫,阻化采空区浮煤,同时在工作面推进过程中,在两巷间隔一定距离构筑漏风密闭,有效控制漏风,并使采空区浮煤的氧化得到了有效控制。
In order to prevent and control the spontaneous combustion occurred in the 15102 coal mining face of Shigang Mine,the paper analyzed the dangerous factors of the spontaneous combustion occurred in 15102 coal mining face.Borehole drillings along No.14 seam for grouting was made and the MEA foam were grouted in the seam to resist the weathering of the coal on floor of goaf.During the coal mining advanced forward,there were ventilation leakage dam built with a certain distance in the two gateways to effectivel...
