Abstract
Изобретение относитс к горному делу и используетс в Механизированных агрегатах и комплексах. Цель - повышение безопасности в лаве и снижение трудоемкости вспомогательных ручных работ. Дл удержани забо 7 от обрушени вдоль него располагают сплошную полосу гибкого ограждени С ПГП) 1. Ее удерживают на определенной высоте посредством гибких св зей (цепей). Последние соедин ют ПГО 1 с секци ми крепи 2. Удерживают забой 7 от обрушени прижатием к нему ПГО 1 башмаками гидроцилиндров 5. В районе выемочной машины ГПО 1 отвод т от забо , пропускают между вертикалытыми роликами и удерживают горизонтальными роликами 11. Это обеспечивает ограждение рабочего пространства и обслуживающего персонала от возможного обрушени и попадани кусков и глыб горной массы. После прохода машины одновременно с вьщвижкой секций крепи 2 ПГО 1 перемещают и., раздвига гидроци- линдры 5, прижимают к забою. 5 ил.The invention relates to mining and is used in mechanized units and complexes. The goal is to increase safety in lava and reduce the labor intensity of auxiliary handicrafts. In order to keep the 7 from collapsing along it, a continuous strip of flexible casing C GWP is placed. 1. It is kept at a certain height by means of flexible links (chains). The latter connect PGO 1 with lining sections 2. Hold PGO 1 against collapse by pressing PGO 1 with hydraulic cylinders 5 shoes. space and staff from the possible collapse and falling pieces and blocks of rock mass. After the passage of the machine, simultaneously with the installation of the lining sections, the support 2 PGO 1 is moved and., Moving apart, the hydraulic cylinders 5 are pressed to the bottom. 5 il.
