摘要
提出了通过建立密闭墙和释放井的方法对采空区进行处理的采空区顶板控制方法,并通过实例介绍了密闭墙结构的确定方法,并对密闭墙进行了受力分析。同时对释放井的直径也进行了设计计算。
This paper proposes the erection of sealing walls and pressure releasing shafts as a treatment to underground coal mine gob areas. Through the use of actual cases, the paper presents methods to determine the structure of sealing wall as well as an analysis of the stress situation of the sealing walls when they are exposed to extreme forces. Besides, calculation is also carried out in this paper for the design of the diameters of such releasing shafts.
