Optimization Layout Method of Coal Mining and Filling Space in Deep Mine
Taking Tuncheng Coal Mine as an example,an optimization layout method of coal mining and filling space in deep mine was introduced.In this method,a new jigging sorting system was installed in the underground transfer chamber,and simultaneously arranged in 1303N-1 and 1304N working faces.Through application,it is known that the surrounding rock strength of the site working face is high,indicating that the surrounding rock of the roadway is in line with the specified requirements,which can improve the safety of underground operation,and confirm that the optimization layout method of coal mining and filling space in deep mine has high application value.
