A method for roadway supporting includes blast-hole drilling, installation and fixation of tubular injection roof bolts there by mechanical method, and pumping-in curing solution. Before installation of roof bolt one fits on it and fixes elastic shell. Fixation of roof bolt is carried out at roadway construction, and injection of curing solution to elastic shell is carried out through perforated section of the roof bolt at stage of formation of zone of destroyed rocks. After injection of curing solution, as that self-curing material is used, the mouth section of the injection roof bolt is sealed. This makes it possible to suppress stratification of contour rocks at roadway construction and disintegration of those at the stage of formation of zone of destroyed rocks round the working, this provides increase of stability of mine workings. |
