Abstract

Przyczołowa obudowa podporowo-kotwowa, zawierająca zasadniczo prosty odcinek kształtownika o profilu otwartym połączony z żerdzią kotwy, charakteryzuje się tym, że połączenie kształtownika (1) z żerdzią kotwy (3) zrealizowane jest w układzie szeregowym za pomocą elementu mocującego, utwierdzonego w części końcowej kształtownika (1) i posiadającego otwór lub wycięcie, w którym usytuowany jest odcinek końcowy żerdzi kotwy (3), zaopatrzony w element blokująco-dociskający, przy czym średnica otworu lub szerokość wycięcia jest większa niż zewnętrzna średnica żerdzi kotwy (3) ale mniejsza od minimalnego wymiaru przekroju poprzecznego elementu blokująco-dociskającego. Sposób zabezpieczania stropu w przyczołowej części wyrobiska ścianowego za pomocą przyczołowej obudowy podporowo-kotwowej, polega na tym, że na odcinku objętym obwałem lub opadem skał stropowych, wykonuje się sztuczny strop, którego zasadniczym elementem są stropnice przyczołowe w postaci kształtowników (1), jednym końcem podparte na stropnicach sekcji ścianowej obudowy zmechanizowanej (10), a drugim końcem połączone z żerdzią kotwy zabudowanej w stropie lub pokładzie.The frontal support and anchor casing, containing a substantially straight section of the profile with an open profile connected to the anchor rod, is characterized by the fact that the connection of the profile (1) with the anchor rod (3) is realized in series by means of a fastening element fixed in the end part of the profile (1) and having a hole or cutout in which the end section of the anchor rod (3) is located, provided with a locking and clamping element, the hole diameter or cutout width greater than the outer diameter of the anchor rod (3) but smaller than the minimum dimension cross-section of the blocking and pressing element. The method of securing the ceiling in the frontal part of a longwall excavation by means of a frontal support and anchor casing consists in the fact that, on the section covered by the fall or fall of ceiling rocks, an artificial ceiling is made, whose main element is the frontal girders in the form of sections (1), with one end supported on the girders of the wall section of the powered roof support (10) and connected to the anchor rod built into the ceiling or deck at the other end.
