1. The invention concerns a mechanised lining of intersection of wall excavation and heading comprising two sections interconnected and run one in relation to the other by means of at least one hydraulic servo-motor, and each section consists of roof-bar supported by sill piece via hydraulic servo-motor mounted on beam connected to sill piece by string and supported by prop, characterised in that it has a protrusion (17) symmetrical in relation to vertical plane of lining's symmetry, the protrusion (17) makes working surface of roof-bar (1) and sill-piece (8).<IMAGE>
