Increasing the stability of mine stopes by injection hardening of the near-contour mass

Abstract

Abstract The possibility of improving the mechanization of strengthening the near-contour mass of stope is considered. Variants of improving the supply of injection solution into the mass are proposed, various technological schemes for supplying the injection solution into the near-contour mass are considered, and an optimal injection scheme is proposed. A classification of injection solutions is made in terms of the possibility of their use in rocks of different stability and injection technology.
