Abstract

Method for application of shotcrete coating in vertical mine workings includes coaxial placement of nozzle in working, connecting it with material pipeline to sputtering-concrete machine, supply of curing mix from it to the nozzle under pressure, this is directed at leaving the nozzle to conical sprinkler installed coaxially. To obtain uniform in physical—chemical properties layer, from mouth of the muzzle the mix is directed through opening in the disc to which at distance in parallel another disc is attached, with conical splitter placed on its surface. At that the mix after passing the opening in disc is directed to conical splitter and due to interaction with it in space between parallel discs and out of boundaries of that space one forms radial-circular flow axis of which is normal to surface of vertical working in projection to vertical plane. At that one displaces the nozzle with the discs along the axis of the working with formation of layer of curing mix on its surface, its thickness is determined by given formula.
