Bolt support can play a role.
Does the subject want to ask "what role can bolt support play?" Composite beam action, span reduction action.

1, the function of composite beam: the anchor rod combines multiple rock strata into a whole to form a composite beam structure, which improves the bearing capacity and bending stiffness of rock strata and prevents them from bending, deformation and fracture.

2. Reduce the span: the anchor can reduce the bending deformation of the rock stratum with large span, reduce the internal stress of the rock stratum, and prevent the rock stratum from bending and collapsing.
