In responding to the problems identified, a countermeasure of bolt-mesh-anchor-shotcrete + floor-bolt + truss coupling supporting is proposed, namely using shotcrete to seal surrounding rock, bolt-mesh support to release deformation energy, floor bolt to transfer floor heave plastic slippage force, anchor-truss support to control the deformation of surrounding rock. Therefore, the effective deformation control of deep high stressed soft rock roadway can be achieved.
