Abstract
Sposób wykonywania ochronnych pasów podsadzki utwardzanej, zwłaszcza dla ochrony chodników przyścianowych w podziemnych wyrobiskach zakładów górniczych polega na tym, że najpierw do podwieszonego na zawiesiach (3) pod stropnicą (2) sekcji obudowy zmechanizowanej (1) od strony zrobów płóciennego worka (4) typu big - bag wprowadzana jest pod ciśnieniem hydrauliczna mieszanina podsadzkowa aż do wypełnienia worka (4) do wysokości dolnej powierzchni stropnicy (2) sekcji obudowy zmechanizowanej (1). Następnie, zgodnie ze znaną technologią urabiania, następuje przesunięcie sekcji obudowy zmechanizowanej (1) w kierunku urabianej ściany z jednoczesnym uwolnieniem worka (4) z zawiesi (3) pod stropnicą (2) tak, że otwór worka (4) znajduje się pod odsłoniętym stropem i ciągłym wprowadzaniem pod ciśnieniem hydraulicznej mieszaniny podsadzkowej, przy czym wprowadzanie pod ciśnieniem hydraulicznej mieszaniny podsadzkowej prowadzone jest aż do wypełnienia przestrzeni między napełnianym workiem (4) a odsłoniętym za stropnicą (2) sekcji obudowy zmechanizowanej (1) stropem. W tym samym czasie na zawiesiach (3) pod stropnicą (2) zawieszany jest nowy, pusty płócienny worek (4) i rozpoczyna się wprowadzanie do niego pod ciśnieniem hydraulicznej mieszaniny podsadzkowej. Obudowa zmechanizowana do wykonywania ochronnych pasów podsadzki utwardzanej, zwłaszcza dla ochrony chodników przyścianowych w podziemnych wyrobiskach zakładów górniczych ma do stropnicy (2) sekcji obudowy zmechanizowanej (1) od strony zrobów (tyłu sekcji) korzystnie od spodu mocowane zawiesia (3), korzystnie haki, dla podwieszania płóciennego worka (4) typu big - bag, a z boku sekcji obudowy zmechanizowanej (1) zamontowana jest dwuczęściowa tama izolująca (6), przy czym górna część tamy izolującej (6) mocowana jest nierozłącznie do stropnicy (2) sekcji obudowy zmechanizowanej (1).The method of making protective belts of hardened proppants, especially for the protection of longwall galleries in underground mine headings, consists in the fact that first to the suspended on slings (3) under the girder (2) the mechanized housing section (1) from the side of the canvas bag work (4) big-bag is pressurized with hydraulic filling mixture until the bag (4) is filled to the height of the bottom surface of the girder (2) of the powered support section (1). Then, in accordance with known mining technology, the powered casing section (1) moves towards the excavated wall while releasing the bag (4) from the sling (3) under the girder (2), so that the opening of the bag (4) is under the exposed ceiling and continuous feeding of the hydraulic filling mixture under pressure, wherein the feeding of the hydraulic filling mixture under pressure is carried out until the space between the filled sack (4) and the exposed behind the girder (2) roof section of the powered roof support (1) is filled. At the same time, a new, empty canvas bag (4) is hung on the slings (3) under the girder (2) and the hydraulic filling mixture under pressure begins to be introduced into it. The mechanized housing for making protective belts of hardened proppants, especially for the protection of longwall galleries in underground excavations of mining plants has to the girder (2) of the mechanized housing section (1) from the goaf side (back of the section) preferably from below fixed slings (3), preferably hooks, for suspending a canvas bag (4) of the big-bag type, a two-part insulating dam (6) is mounted on the side of the mechanized housing section (1), the upper part of the insulating dam (6) is permanently attached to the girder (2) of the mechanized housing section (6) 1).
