Abstract: In view of the problem of the failure of the original support due to the influence of the goaf covered with 3 号 coal during the excavation of the auxiliary underground inclined shaft in Wangmangou Mine, a combined support mode of Bolt + anchor rope + shelf + metal mesh + shotcrete was established, the relative changes of the two sides and the roof were fast and then slow, and tended to be stable in the 2nd and 4th week, respectively. The maximum values of the roof and the floor moving closer and the two sides convergence were 71.5 mm and 22.4 mm. The reinforcement measures effectively control the deformation of the surrounding rock of the roadway and ensure the safe and smooth passage of the working face through the overlying goaf.
