Abstract

Изобретение относитс  к горному делу, а именно к средствам креплени  подготовительных горных выработок угольных шахт и рудников. Целью изобретени   вл етс  увеличение несущей способности крепи. Крепь содержит вертикальные стойки 1, состо щие из верхних 2 и нижних 3 частей, соединенных между собой узлами податливости 4. На верхних торцах стоек 1 закреплена гибка  ст жка (ГС) 5, представл юща  собой отрезок каната с закрепленными на его концах фиксирующими элементами 6. Между стойками 1 на ГС 5 расположена составна  балка (СБ) 7, имеюща  верхнюю часть 8, нижнюю часть 9 и опорную платину 10. Под воздействием горного давлени  СБ 7, смеща сь, нагружает ГС 5. При этом ГС 5, работа  на раст жение, создает на нижней части 9 СБ 7 поперечную распределенную нагрузку, частично уравновешивающую нагрузку от горного давлени , и тем самым увеличивает несущую способность крепи. 10 ил.FIELD OF THE INVENTION The invention relates to mining, namely to means of fixing preparatory mine workings of coal mines and mines. The aim of the invention is to increase the carrying capacity of the support. The support contains vertical uprights 1 consisting of upper 2 and lower 3 parts interconnected by nodes of compliance 4. At the upper ends of the uprights 1, a flexible tie (HS) 5 is fixed, which is a piece of rope with fixing elements 6 fixed on its ends Between the pillars 1 on HS 5 there is a composite beam (SB) 7, having an upper part 8, a lower part 9 and a supporting plate 10. Under the influence of rock pressure, the SB 7, shifting, loads HS 5. At the same time HS 5, work on height on the bottom of the 9 sb 7 transverse distributed load, partially balancing the load from the rock pressure, and thereby increases the bearing capacity of the lining. 10 il.
