工作面附近小窑破坏区自燃井下治理技术

Underground Mine Coal Spontaneous Combustion Control Technology of Seam Destroyed Zone in Previous Small Mine near Coal Mining Face

通过井下钻孔探测、气体分析等手段对裕兴煤矿1601工作面密闭内的小窑老空区煤自燃地点进行分析,在井下应用喷浆堵漏、加固密闭、钻孔灌浆等有效的防灭火技术措施,对1601小窑老空区煤自燃进行了有效地治理,使小窑自燃对裕兴矿安全生产的影响大大降低,有效地指导了该矿的安全生产。

With the exploration of the underground borehole, the gas analysis and other means, an analysis was conducted on a coal spontaneous combustion location in the mining goal of a previous small mine sealed in No. 1601 coal mining face of Yuxing Mine. The grout spraying for leakage sealing, reinforcement airtight, borehole grouting and other effective fire prevention and control technical measures were applied to the effective control of the coal spontaneous combustion in the mining goal of the previous small mine in No. 1601 coal mining face. The spontaneous combustion affected to the safety production of Yuxing Mine was highly reduced and those technical measures would effectively guide the safety production of the mine.
