Abstract Mining face roadway support is related to safety production in the mine. Due to the weakness of overlying rocks of the mining work, it is prone to roof fall, and there will be occasional nicking and floor heave. In order to solve the production difficulties on the spot, on the basis of value simulation and theoretical calculation, nonlinear large deformation mechanical design method is used to design the supporting way of the roadway, and the construction requirements are described in detail. Finally, observation is conducted on the design scheme and construction results in the mine. Observation results show that the displacement of the roadway has been effectively controlled and the supporting scheme is feasible.
