摘要
石圪台煤矿31201工作面存在上覆采空区及周边小窑采空区,受采动影响井上下采空区易形成漏风通道。为验证本采空区与上覆采空区、小窑采空区及地表裂隙之间存在漏风通道,通过以释放SF6示踪气体的技术手段进行验证,并对工作面的漏风量进行测定,为完善工作面通风系统提供数据参考。
There is a goaf in the overlying goaf and surrounding small kiln in the 31201 working face of Shigetai Coal Mine.It is easy to form a wind leakage channel in the upper and lower goaf by the mining.In order to verify the existence of air leakage passage between the goaf and the overlying goaf,the small kiln goaf and the surface fissure,the technology is verified by the technical means of releasing the SF6 tracer gas,and the air leakage of the working face is measured.Provide data reference for improving the working face ventilation system.
