The invention relates to the coal industry, in particular, to the mechanization of fixing cleaning faces, mainly thin and very thin flat and inclined seams.

The purpose of the invention is to increase the stability of the lining and accelerate the process of shifting.

FIG. 1 shows lining sections, general side view; in fig. 2 - the same, after shifting the even sections of the lining on the step of their shifting; in fig. 3 - lining, general view in the plan; in fig. 4 - the same, after shifting even sections.

The pneumatic bolting sections consist of a downhole and auxiliary parts, spaced from one another by a distance equal to the aisle for the workers and the step of the slide mounting, pneumatic cylinders, 1 of which are located between the ceiling 2 I and the base 3.

 The pneumatic cylinders I are connected to the overlap of I 2 and the base 3 by means of bolts 1 4. On the sides of the pneumatic cylinders 1 are equipped with stabilizing devices 5,

consisting of two pivotally connected to each other in the middle part I crosswise with levers, curved ends 6 and 7 of which are located on the side of the worked-out space, hinged to the brackets 8 and 9, installed respectively on the overlap 2 and the base 3, and their downhole ends 10 and 11, which are on the side of the cleaning hole, are hinged to the sliders 12 and 13, which are movably mounted on the guides 14 and 15, located i on the slabs 2 and the bases 3 with hand clearing flank. Pneumatic-balloon lining sections are grouped into odd and even rows. Sections of an odd row are connected between each other by a flexible connecting element 16, and sections of an even row are connected by a flexible connecting element 17, which is movably fixed on a guide beam 18, which is located at the preparatory working. ,

All air bellows, which are located on the side of the developed space, are sideways equipped with jacks 19 advances, and air bellows, which are on the side of the refining slab, have 20 movement jacks, one ends of which are hingedly retracted to the sliders 12, and others - from air bellows, located on the side of the goaf, to the bases of the landing pillars 21, and

cylinders located on the side of the clearing slab - to the base beam 22.

The support works as follows.

After excavation of the coal along the entire length of the lava, the base beam 22 is moved to the bottom of the slide of the support bolt to the face, for which include shifting jacks 20. Moving the base beam 22 to a new place, load the even sections of the lining and, turning on the jacks 19 advancing the even sections of the lining, pull the even sections of the lining to the base beam 22, which is held in place by a group of jacks 20 of the odd sections of the support. Then the shifted sections of the lining burst between the roof and the soil of the reservoir, unload and move the odd sections of the lining to a new place and burst them between the soil and the roof of the reservoir. Then, landing pillars 21 are moved to them and they are pulled apart between the soil and the roof of the reservoir, after which the cycle of work on excavation of coal is repeated, etc.

The odd lining sections to prevent them from sliding down along the lava are interconnected by a flexible connecting element 16, and the even ones by a flexible connecting element 17, which are moved together with their groups of the lining section: while keeping the passage for people between the air bellows.

Claims (1)

Invention Formula Pneumatic supports, including a base beam, with which the odd and odd sections of the support are connected with jacks of the advancing, each of which contains a ceiling and a base, between which are mounted pneumatic cylinders connected with their side levers that are hinged and crosswise, which are hinged between each other in the middle part and hinged with one end on the ceiling and the base, characterized in that, in order to increase the stability of the support and accelerate the process of shifting, the support sections are made of bottomhole holes and the main parts, the overlaps and the bases of each of which are made with guides, the downhole ends of the levers are installed in the guides by means of sliders, and their filling ends are hinged on the ceilings, and the bases, with the shifter jacks mounted on the bases on both sides of air bellows and hinged one ends on the sliders. 12 "j t / / / 7 / / / f7 / / // // f / / j " (pfJ2.f t -e Fig.z
