Zusammenfassung:	FIELD: mining industry. SUBSTANCE: this is used in construction of vertical mine shafts with using cast-in-place reinforced concrete in difficult mining and geological conditions. Mine shaft lining incorporates load-bearing reinforced concrete shell, compensation shell which is divided by stiffening ribs with creation of vertical passages being filled with pliable foamed material, anchor rods which are secured in rock mass and connected with load-bearing reinforced concrete shell. Anchor rods are secured in rock mass at acute angles to walls of vertical mine shaft in vertical plane and they are connected with load-bearing reinforced concrete shell by flexible steel links (ropes, rods) located in stiffening ribs of compensation shell. Anchor rods can be used for fastening to them of metal net for temporary lining of mine shaft walls. EFFECT: higher efficiency. 1 cl, 4 dwg
