A method for anchor fixation of a working includes determination of zone of destroyed rocks, drilling blast holes in contour of the working with depth that is larger than the depth of destroyed rocks, installation and fixation of anchor fixation in the blast holes, turning on and fixation of support washers to the contour of the working. At the section of destroyed rocks the blast hole is drilled with diameter not smaller than two diameters of the anchor. After fixation of the anchor the gap between that one and the wall of the blast hole is filled with heat-conductive filler, with arrangement of heat exchange with air of the working by means of support washer as a radiator. |
