MINE LINING ANCHOR

FIELD: mining industry, in particular, anchors for reinforcing contour of mines. ^ SUBSTANCE: mine lining anchor includes load bearing rod of composite material, having head part and tail, provided with thread and nut. A special feature is that rod is made solid in cross-section, is provided with widened sections on head part and tail, made as a whole with main part of rod, thread of tail is positioned immediately in its widened section, widened section in head part is provided with screw groove, while internal diameters of screw groove and tail thread match diameter of main section of rod between widened sections or exceed it, and tail nut is made of highly strong polymer. Invention provides for expansion of operation capabilities and reliability of mine lining anchor by providing high load carrying capacity in yielding mode, due to improved mixing of reinforcing composition by anchor and increased area of contact with it while preserving even strength of anchor along its length, optimal combination of properties of material with geometry of cross-section of anchor rod with simultaneous facilitation of mounting the anchor into blast hole. ^ EFFECT: increased reliability. ^ 7 cl, 1 dwg
