Abstract
Изобретение относитс к горному делу и может быть использовано дл поддержани горной выработки (ГВ). Цель - повышение надежности поддержани ГВ при пересечении ею угольного пласта. В боках ГВ 1 выполн ют разгрузочные полости в виде щелей на контакте верхней части угольного пласта 2 с вмещающими породами. В щел х размещают металлические подхваты 3, а между ними эластичные баллоны. Затем устанавливают остальные элементы крепи: зат жку, арки 6 и ножки 7 с распором в контур ГВ 1. После этого производ т тампнаж закрепного пространства 10. Арки могут быть соединены замком 8, при этом их опирают на выступающие в ГВ 1 концы металлических подхватов. 4 ил.The invention relates to mining and can be used to maintain mining (HB). The goal is to increase the reliability of maintaining the GW when it crosses the coal seam. In the sides of HS 1, discharge cavities are made in the form of slots at the contact of the upper part of the coal seam 2 with enclosing rocks. In the slits, metal supports 3 are placed, and between them elastic cylinders. Then, the rest of the lining elements are installed: a stopper, arches 6 and legs 7 with expansion into the HW circuit 1. After this, the fixing space 10 is tamped. The arches can be connected with lock 8, while they are supported by protruding ends of H. 4 il.
