Abstract
Przedmiotem wzoru użytkowego jest kaszt podporowy z uszczelniającym zestawem przeznaczony do podpierania stropu wyrobiska górniczego zwłaszcza w trakcie pociągającej za sobą duże zagrożenie tąpaniami eksploatacji górniczej w systemem ścianowym. Na jego górnych krawędziach od strony stropu wyrobiska w płaszczyźnie poziomej sytuowany jest uszczelniający zestaw drewnianych prostokątnych wysuwnych wypełniających blatów o zróżnicowanych grubościach oraz wymiarach dostosowanych do wymiarów poziomych belek kasztu (1). Grubość wypełniających blatów jest zróżnicowana, zawsze mniejsza od grubości belek, z których zbudowany jest podporowy kaszt (1), a ich liczba dobierana i ustalana jest każdorazowo dla konkretnych warunków. Wypełniające blaty mają poprzeczne nacięcia ułatwiające ręczne przełamanie ich na krótsze odcinki bez stosowania narzędzi.The subject of the utility model is a support castle with a sealing set intended for supporting the mining excavation ceiling, especially during a high risk of mining exploitation in the longwall system. On its upper edges from the side of the excavation ceiling in the horizontal plane there is a sealing set of wooden rectangular withdrawable filling tops of various thicknesses and dimensions adapted to the horizontal dimensions of the beams (1). The thickness of the filling countertops is varied, always smaller than the thickness of the beams from which the supporting chest is made (1), and their number is selected and determined each time for specific conditions. Filling countertops have transverse incisions to facilitate manual breaking them into shorter sections without using tools.
