塔山矿石炭二叠系上覆火区危险性评估与防治措施

Risk Assessment and Control Measures for Overlying Fire Zone of Permo- carboniferous System in Tashan Coal Mine

为了查明塔山矿8107工作面上覆侏罗纪古窑采空区探测到的疑似发火区域,通过同位素测氡法探测火区具体范围并定量分析其发展趋势,同时采用工业电视钻孔观测结果定性分析气体侵入可能性。此外,通过在工作面采取一系列防灭火措施后,确保了8107工作面的安全顺利回采。

In order to detect suspected fire zone at 8107 working face of Tashan Coal Mine in overlying Jurassic ancient kiln gob,isotopic radon measurement method was used to detect the fire zone and quantitatively analyze its evolution trend. Meanwhile,industrial television drilling analysis was used to qualitatively analyze the possibility of fire incursion. Additionally,a series of fire prevention technology was prepared,which guaranteed safely mining of 8107 workface.
