摘要
Abstract
The 113upper05 working face is an isolated island working face mining,with only 5 m of coal pillars left in the two roadways and goaf.The coal pillars are prone to fracturing and pressing crispy,and the air leakage channels in the goaf are complex.The prevention and control problem of spontaneous combustion are serious.Through the study of the air leakage characteristics of the 113upper05 stoping goaf,the air leakage channels and tendencies in the goaf are identified.The development trend and law of filling and retention covering agents are applied to prevent and control air leakage in the goaf air leakage area.Finally,the filling and retention covering agent governance technology is used to prevent and control air leakage in the goaf.Firstly,the pressure difference and energy level determination methods are used to qualitatively analyze the air leakage sources and sinks in the goaf,and SF6 tracing method is used to detect and measure the sealing effect.The results show that the use of filling type and sealing isolating type sealing technique effectively control the air leakage in the goaf of the 113upper05 fully mechanized mining face,reduce the spontaneous combustion danger of remaining coal in the goaf,and ensure the safety production of the 113upper05 fully mechanized mining face.关键词
