Изобретение относитс к горно-добывающей промьшшенности и может быть использовано при креплении горных выработок , поддерживаемых в услови х всестороннего горного давлени и силь нопучащих пород почвы.The invention relates to the mining industry and can be used in the fastening of mine workings maintained under conditions of comprehensive rock pressure and strong rock strata.
.Целью изобретени вл етс снижение трудоемкости горно-проходческих работ и предотвращение пучени пород почвы.The object of the invention is to reduce the labor intensity of the mining and tunneling works and to prevent the soil from heaving up.
На чертеже приведена замкнута крепь горной выработки.The drawing shows a closed support mining.
Крепь состоит из верхн ка 1, двух боковых элементов 2, зат жек 3 и элемента 4 обратного свода, установлен- ного выпуклой стороной в направлении выработаннолго пространства 5 и об- разукнцёго в почве выработки аккумулирующую полость 6, заполненную разрыхленной породной массой.The support consists of the top 1, two side elements 2, the rear 3, and the return arch 4, installed with the convex side in the direction of the developed space 5 and the accumulating cavity 6 formed in the soil and filled with a loosened rock mass.
В услови х интенсификации процессов пучени пород почвы разрыхленна Under the conditions of intensification of the processes, the heel rocks of the soil are loosened.

породна масса играет роль демпферной податливой подушки за счет частичного заполнени пустот пучащими породами и собственно уплотнени разрыхленной массы. Отсутствие св зей между отдельными кусками разрыхленной породной массы содействует равномерному распределению нагрузок, т.е. элемент 4 обратного свода находитс в услови х равномерного нагру- жени , что существенно улучшает услови работы крепи в целом.The rock mass plays the role of a damper cushioning cushion due to the partial filling of the voids with spreading rocks and the actual compaction of the loosened mass. The absence of connections between individual pieces of loosened rock mass contributes to the uniform distribution of loads, i.e. element 4 of the invert is under uniform loading conditions, which significantly improves the working conditions of the support in general.
Монтаж крепи производ т следую- щим образом.The mounting is done in the following way.
Отбойку породы производ т на полное сечение, т.е. контур обратного свода довод т до круглой формы. Уборку породы осуществл ют в пределах областей А и В, затем укладывают зат жки 3, на которые устанавливают элемент 4 обратного, свода.Rock cutting is performed on the full section, i.e. the outline of the invert is brought to a round shape. The rock is harvested within areas A and B, then the puffs 3 are laid, on which element 4 of the inverse, dome is installed.
Монтаж остальной части крепи производ т по известной технологии.Installation of the rest of the lining is made by known technology.
