Mining lining structure

Abstract

The application concerns the construction of mining lagging, used particularly in securing roadway workings. The mining lagging (1) is a truss formed by inseparably connected longitudinal bars (2) and transverse bars (3). The longitudinal bars (2) have hook bends (2.1) at one end, and hook bends (2.3) with additional V-shaped recesses (2.4) at the other end. At least one of the longitudinal bars (2) has a hook bend (2.1) bent with its free end (X) towards the shaft (2.5) by a distance (b4) smaller than the thickness (g) of the hook transverse bar (3.1).
