Abstract

Przedmiotem zgłoszenia jest kaszt górniczy do podparcia stropu, składający się z ułożonych w warstwach jedna na drugiej belek, przy czym belki kolejnych warstw w miejscu styku posiadają wręby o długości co najmniej równej szerokości belek, według wynalazku charakteryzuje się tym, że jest utworzony z usytuowanych w sposób ciągły j eden za drugim kasztów (1, 3), które są oddzielone od siebie łącznikami (2). Zgłoszenie obejmuje także sposób wytwarzania kasztu górniczego, w którym układa się w warstwach jedna na drugiej, belki, przy czym belki kolejnych warstw w miejscu styku posiadają wręby o długości co najmniej równej szerokości belek, według wynalazku charakteryzuje się tym, że wytwarza się belki różnych typów, mające wszystkie jednakową długość (1) i szerokość (b), ale różniące się wysokością, jak również miejscem usytuowania i długością wrębów, a następnie z tych belek buduje się usytuowane w sposób ciągły jeden za drugim kaszty (1 i 3), które są oddzielone od siebie łącznikami (2).The subject of the application is a mining chest for supporting a ceiling, consisting of beams arranged in layers one on top of the other, wherein the beams of subsequent layers have notches at the point of contact with each other with a length at least equal to the width of the beams. According to the invention, it is characterized in that it is formed from continuous chests (1, 3) arranged one behind the other, which are separated from each other by connectors (2). The application also covers a method for producing a mining chest, in which beams are arranged in layers one on top of each other, wherein the beams of subsequent layers have notches at the point of contact with each other with a length at least equal to the width of the beams. According to the invention, it is characterized in that beams of different types are produced, all having the same length (1) and width (b), but differing in height, as well as in the location and length of the notches, and then chests (1 and 3) arranged continuously one behind the other, which are separated from each other by connectors (2).
