1. A method for arrangement of floor installation in wall excavation of an underground mine, provided with protective lining, wherein the floor installation has pipe sections connected by means of flexible couplings designed for connecting floor pipes and is suspended on strings below the roof-bar between pillars of the protective lining and workings protection, characterised in that the floor pipeline (1) is divided into sections of length equal to every second lining unit (3) and the units are connected by means of elastic couplings (2) located half width of the lining unit (3), but the units of the protective lining (3) are dislocated in such a way, that the first to move is the unit (I) of the lining (3) in the area with coupling (2), after which the adjacent unit (II) is moved.2. A device for arrangement of floor installation in wall excavation of an underground mine, provided with protective lining, wherein the floor installation is suspended on strings below the roof-bar between pillars of the protective lining and workings protection, characterised in that it has a shape of a flat beam (13), bent at the end, and the beam (19) is fixed to the workings protection (16) and located parallel to foot pieces, and its end (15), bent upwards, is placed at the side of the front (4) of the excavation, but the beam (19) is located below the floor pipeline (1) arranged at a height (h) of maximal clearance (d) between the pillars (14) and the workings protection (16).<IMAGE>
