A method of anchoring a massif includes drilling of a line of inclined twin bore holes that intersect one with another at the bottom, with installation to the bore holes of reinforcement anchor rods with fixation of those with curing material. As reinforcement rods one uses tubes with outer diameter that is equal to diameter of the bore holes, and fixation of the tubes in the bore holes is carried out with pumping in curing material into the tubes, with filling with curing material of the places between the tubes in intersection of bore holes.
