Изобретение относитс к горной науке, в частности к креплению под-земных выработок в сложных горно-геологических услови х и при про влении горных ударов.The invention relates to mining science, in particular to the fastening of underground workings in difficult mining and geological conditions and in the development of rock bursts.
Целью изобретени вл етс повышение устойчивости крепи при ее работе в сложных горно-геологических услови х и при про влении горных ударов.The aim of the invention is to increase the stability of the support during its operation in difficult geological conditions and in the development of rock bumps.
На фиг.1 изображена металлическа арочна ограниченно-податлива крепь на фиг.2 - разрез А-А на фиг..Fig. 1 shows a metallic arched limited-flexible support in Fig. 2 - section A-A in Fig.
Крепь состоит из криволинейного верхн ка J из спецпрофил , составных стоек 2, выполненных в виде труб, при этом верхн часть 3 стойки соединена внахлест с верхн ком 1 посредством хомутов 4, а ограничители податливости в виде кольцевых выступов образованы фланцами 5 и 6, расположенными на сопр гаемых концах верхне 3 и нижней 7 частей стойки, фланцы соединены между собой болтами 8.The support consists of a curvilinear top J of a special profile, composite struts 2, made in the form of pipes, while the upper part 3 of the stand is overlapped with the top 1 by clamps 4, and the limiters of compliance in the form of annular projections are formed by flanges 5 and 6 located on the mating ends of the upper 3 and lower 7 parts of the rack, the flanges are interconnected by bolts 8.
Возведение крепи осуществл етс следующим образом.The construction of the lining is carried out as follows.
На концах верхн ка I из спецпрофил с внутренней стороны зажимаютс верхние части 3 стоек 2 хомутами 4, которые с нижней стороны имеют фланцы 5. Затем собранна таким образом арка ставитс на фпанцах 6 стоек 2 и зажимаетс болтами 8. Вначале крепь At the ends of the upper I of the special profile, the upper parts 3 of the uprights 2 are clamped from the inside by clamps 4, which have flanges 5 on the lower side. Then the arch assembled in this way is put on the flanges 6 of the uprights 2 and clamped by bolts 8. First,

работает в режиме податливости, осуществл етс проскальзывание верхн ка 1 по верхней части 3 стойки 2 до упора торца верхн ка 1 во фланцы 5, после чего крепь переходит в жесткий режим работы.It works in the compliance mode, the top 1 slides along the top 3 of the rack 2 until the top 1 faces against the flanges 5, after which the support goes into a hard mode of operation.
При необходимости применени крепи замкнутой формы следует к стойкам крепи с нижней стороны подставить и закрепить аналогичную описанной арку.If it is necessary to use the support of a closed form, it is necessary to substitute and fix the same arch described above to the supports of the bottom side.
