Description

Изобретение относитс  к горномуделу , в частности к креплению подземных выработок и может быть использовано в горной промьшигенности дл  креплени  восстающих выработок, например- углеспускных и ходовых печей, испытывающих значительные деформации при выемке крутых и наклонных пластов угл  системами разработки со щитовыми и гибкими перекрыти ми.The invention relates to the mining industry, in particular, to the fastening of underground workings and can be used in mining industry for fastening rising workings, for example, coal-bearing and running furnaces that experience significant deformations during excavation of steep and inclined coal seams with development systems with panel and flexible ceilings.

По основному-автi св. № 613109 известна крепь дл  горных выработок, вк.пючающа  сегменты с кольцевыми и радиадтьнымй ребрами жесткости/ кольцевьп«1и центрирующими по сами и кольцевыми канавками, а также эластичные баллоны, закрепленные на сегментах , причем баллоны выполнены с утолщенной боковой стенкой, обращенной во внутрь выработки, и кольцевыми центрирующими по сами и. канавками, а сегменты размещены в утолщенной стенке баллона так, что одно из его кольцевых ребер жесткости соединено с центрирующим по сом, а другое огибает центрирующую канавку.ГИ,On the main-avi sv. No. 613109 is a well-known support for mine workings, which includes segments with annular and radial stiffeners / annuli "and centered by themselves and annular grooves, as well as elastic cylinders fixed to the segments, and the cylinders are made with thickened side walls facing inwards and ring centering on themselves and. grooves, and the segments are placed in a thickened wall of the cylinder so that one of its annular stiffening ribs is connected to the centering catfish, and the other bends around the centering groove.

-Однако эта крепь обладает недостаточным сцеплением тюбингов в верхнем кольце, что не обеспечийает надежного креплени  выработок.- However, this lining has insufficient adhesion of tubing in the upper ring, which does not ensure reliable fastening of the workings.

Цель изобретени  -. повышение надежности креплени  выработок.The purpose of the invention is. increase the reliability of fastening workings.

Поставленна  цель достигаетс  тем, что в крепи дл  горных выработок одна из поверхностей взаимодействи  эластичногобаллона в тюбинговом кольце выпо.пнена с выступами и впадинами ,, а друга  - гладкой.This goal is achieved by the fact that in the lining of mine workings one of the surfaces of the interaction of the elastic ballon in the tubing ring is made with protrusions and depressions, and the other is smooth.

Крепь дл  горных выработок состоит из тюбингов 1, включающих эластичный баллон 2 и металлический сегмент 3, размещеннь й в утолщенной стен15 ке 4 баллона 2, о.бращенной во внутрь выработки,.На боковых поверхност х 5, по которым тюбинги 1 .в кольце взаимодействуют друг с другом, выполнены продольные выступы 6 и впа20 дины 7. Причем вЬ1ступы 6 и впадины 7 выполнены при изготовлении тюбинга 1 только на одной боковой поверхности , а на другой они образуютс  при взаимодействии со смежным тю The support for mine workings consists of tubings 1, including an elastic cylinder 2 and a metal segment 3 located in a thickened wall 15 of cylinder 4 2, which is bent inside the mine, on the lateral surfaces 5 along which the tubing 1 in the ring interact longitudinal protrusions 6 and depressions 7 are made with each other. Moreover, b1 protrusions 6 and depressions 7 are made in the manufacture of tubing 1 only on one side surface, and on the other they are formed when interacting with the adjacent ty

Выступы.6 йдного тюбинга 1 вход т во впадины 7 смежного ,and segments 3, creating a radial force that holds the tubing ring in the mine. Tubing 1, resting on each other side surfaces 5, are wedged to form a supporting structure. The protrusions of the 6 tubing 1 entrance into the troughs 7 adjacent,

Возведение предлагаемой крепи осуществл етс  снизу в вверх либо после проведени  выработки на всю ее длину, либо вслед за подвиганием забо  выработки . Смежные тюбинговые кольца во врем  контакта повернуты относительно друг друга на 45°.The erection of the proposed support is carried out from below in upwards, either after carrying out the excavation to its entire length, or after the advancement of the excavation. Adjacent tubing rings are rotated 45 ° relative to each other during contact.

Демонтируетс  крепь сверху по мере погашени  выработки. При этом из одного-двух бёшлонов выпускаетс  воздух и за счёт уменьшени  диаметраThe support is dismounted from above as the production is redeemed. At the same time, air is released from one or two birchlons and due to a decrease in diameter

Кольца тюбинги легко извлекаютс  из выработки.Tubing rings are easily removed from the workings.
