Abstract
A method for the protection of working includes roadway construction, hole drilling, blasting charges of explosive substances there. The dimension of the inelastic strain zone is determined, at the ledge wall, rockbolts are installed to the drilled holes, with length larger compared to the dimension of the inelastic strain zone, but not larger than 10 m. The wells are placed within the sector the top of which goes to the center of symmetry of the working. The axis of symmetry of the sector is normal to stratification of rocks, and the lines that restrict the sector form with the axis angles equal to 8-10°, in the horizontal and vertical holes with length ½-¾ of width of the working drilled at the sidewall explosive blast firing is performed. The horizontal well is drilled lower compared to the yielding unit, and the vertical one – at distance 0.3-0.5 m from the support post.
