高瓦斯矿井采空区堵漏技术研究

Study on Leakage Plugging Technology of Goaf Area in High Gas Mine

随着开采接续的进行,唐口煤矿6310工作面已经形成并且与6309工作面存在漏风趋势。为了提高6310工作面有效风量,避免漏风引发煤自燃危害,采用压能测定与气体示踪的方法确定漏风范围并采取针对性漏风措施。6310工作面有效风量提高了约20 m^(3)/min,6309采空区煤自燃各指标参数正常,为工作面的高产高效提供了保障。

With the continuation of mining,the 6310 working face of Tangkou Coal Mine has been formed and there is a trend of air leakage with the 6309 working face.In order to increase the effective air volume of the 6310 working face and avoid the harm of coal spontaneous combustion caused by air leakage,the method of pressure energy measurement and gas tracing is used to determine the range of air leakage and take targeted air leakage measures.The effective air volume of the 6310 working face is increased by about 20 m^(3)/min.All parameters of coal spontaneous combustion in the 6309 goaf area are normal,which provides guarantee for high yield and high efficiency of working face.
