| Abstract: | Aiming at the serious subsidence of the trench roof in fully mechanized mining face,the multi-level roof deformation control and support technology is put forward.Taking anchor rod and anchor cable as the supporting core,the roof subsidence is reduced by 72.4%and the two sides approach is reduced by 76.1%without increasing the supporting structure. |
