Abstract

Przedmiotem wynalazku jest zespól siatek okladzinowych do zabezpieczania stropu i ociosu wyrobisk górniczych, kazda siatka zespolu ma co najmniej jeden dowolny porzeczny pret (2), wydluzony poza skrajny wzdluzny pret (1) do wielkosci preta (2a) tak, ze siega on poza wzdluzny pret (1) siatki sasiedniego ciagu i jest zaginany w czasie montazu na tym precie wzdluznym, laczac w mate przylegle siatki sasiednich ciagów.The subject of the invention is a set of cladding nets for securing the ceiling and side wall of mining excavations, each set nets has at least one transverse rod (2), extended beyond the longitudinal rod (1) to the size of the rod (2a) so that it extends beyond the longitudinal rod (1) adjacent string netting and is bent during assembly on this longitudinal rod, joining adjacent grids into adjacent string.
