(54) СПОСОБ ПОДДЕРЖАНИЯ КРОВЛИ ВЫРАБОТКИ НА СОПРЯЖЕНИИ С ЛАВОЯ(54) METHOD OF SUPPORTING THE ROOF OF FORECASTING ON THE FOREQUARTERS
Вперед::;и очистного забо на 1530 м в прилегающей к нему выработке , закрепленной арочной податливой крепью из спецпрофил , к арочным верхн кам 1 посредством хомутов 2 или каких -либо других ПEii cпqGOблe-ний креп т поперечины 3, сделанные 5 из спецпрофил , с упорами 4, посредством которых поперечина 3 распираетс в центральную часть арочного верхн к 1.Forward ::; and the clearing indent at 1530 m in the adjoining excavation, fixed with an arched ductile lining from a special profile, to arched upper chambers 1 by means of clamps 2 or any other Пеii cпqGO gli-ny fix crossmembers 3, made 5 of special profiles, with anchors 4, by means of which the cross-member 3 extends into the central part of the arched top toward 1.
Секци крепи сопр жени состоит из двух рам 5 и б, кажда из которых включает основание 7, гидростой ки 8 и перекрыти 9,The lining section consists of two frames 5 and b, each of which includes base 7, hydrostatic 8 and overlap 9,
При передвижке секци крепи сопржени распираетс под поперечины 3, после чего поочередно извлекаютс ножки 10 арочной крепи.When moving the support section, the support section is distributed under the cross-pieces 3, after which the legs of the arch support 10 are alternately removed.
Передвижка секции крепи сопр жени осуществл етс следующим образом. Перед передвижкой рамы 5 секции крепи сопр жени производитс разгрузка ее гидростоек 8, при этом рама б находитс в распертом положении. Затем дроизводитс передвижка рамы 5 посредством гидродомкратов , расположенных между основани ми 7 рам 5 и 6 и распор гидростойками 8 рамы 6. Передвижка рамы 6 производитс аналогично передвижке рамы 5 секции крепи сопр жени . При передвижке рамы 6 арочный верхн к 1 совместно с соединенными с ним поперечиной 3 и упором 4 под действием сил собственного веса падает на почву выработки. Высвобождают -поперечину 3 и упор 4, отсоедин ют их от арочного верхн ка 1 и вновь устанавливают впереди крепи сопр жени под арочный верхн 1 крепи выработки.The movement of the support section is carried out as follows. Before shifting the frame 5 of the support mating section, its hydraulic legs 8 are unloaded, while the frame B is in the open position. Then the frame 5 is moved by means of hydraulic jacks located between the bases 7 and frames 5 and 6 and the frame 8 is struck by the frame 6. The frame 6 is moved along the same way as the frame 5 of the support section. When moving the frame 6, the arched top to 1 together with the crossbar 3 connected to it and the stop 4 under the action of the forces of its own weight falls on the working ground. They release the transverse 3 and the abutment 4, detach them from the arched top 1 and re-install the arbor top 1 of the working support in front of the support.
Применение этого способа по держани кровли выработки на сопр жении с лавой позволит значительно снизить трудоемкость поддержани , снизить расход леса на перекрепление , расширить область применени арочного метсшлического креплени в выработках, прилегающих к очистному забою.The use of this method to keep the roof of the excavation in conjunction with the lava will significantly reduce the labor intensity of maintenance, reduce the consumption of wood for perekrepleniyu, expand the scope of application of the arched mechslichesky mounting in the workings adjacent to the clearing face.
