Прн агнетании воздуха баллоны распираюте  между етенками выработки и еегментами , еоздава  радиальную еилу, удерживающую тюбинговое кольцо в выработке, при этом еегменты, оцира сь друг на друга радиальными ребрами, расклиниваюте , образу  жееткую нееущую конетрукцию.The air is forced between the cylinders of the excavation and its segments, and the radial spindle retaining the tubing ring in the excavation, while the spirals are radiated to each other, forming the same loose conformation.

Возведение крепи оеущеетвл ют после проведени  выработки на вею ее длину либо вслед за нодв гапием забо  выработки. Демонстрируют крень сверху по мере погащенп  выработки. При этом из одного-двух баллонов вынускаетс  воздух и за счет уменьшени  диаметра кольца тюбинги легко извлекают из выработки.The erection of the lining is achieved after the development of its length, or after the node with the gapia of the excavation. Demonstrate a roll from above as it is drained. At the same time, air is exhausted from one or two cylinders and by reducing the diameter of the ring the tubing is easily removed from the mine.
