ABSTRACT:
Before the rock cavity is completely excavated a plurality of arcuated tunnels extending between the top and bottom levels of the intended rock cavity are cut out in the rock outside the future side walls of the cavity, and these tunnels are filled with reinforcing material, preferably concrete, so as to form a rib-like reinforcement structure which is wholly embedded in the rock surrounding the rock cavity.
