Under the influence of excavation engineering, the top floor and the two sides of rock mass of the roadway deform and displace into the roadway, and the phenomenon that the floor of the roadway bulges upwards is called floor heave. The floor heave can increase the moving distance between the top plate and the bottom plate of the roadway, reduce the size of the section of the roadway and prevent normal transportation, passage and ventilation. In order to solve the floor heave problem, a roadway bottom plate needs to be supported by adopting a mode of installing a bottom plate anchor rope, and the method mainly comprises 2 processes of bottom plate pore-forming and anchor rope anchoring.
