Description

f

The invention relates to the mining industry, in particular to the fastening of the workings of the arched section

The purpose of the invention is to reduce the complexity of the construction and increase the efficiency of the lining.

Fig, depicts the location of the reinforcing lining in the preparatory development, common. j in Fig. 2 is the node T in Fig. 1 (the connection of a hydrorack with the upper reinforcing cross T1I | Fig. 3 is a section A-A in Fig. 2 in Fig. 4 is a view B in Fig. 2 | in Fig. 5- section B-B in Fig. 1. (a unit for connecting a hydraulic post with a support and an extended plate) | in Fig. 6 — a clip.

Strengthening lining includes upper to 1 s ynopai-sh 2, hydraulic struts Ee supports AE widest fingers 5, Upper to 1 reinforcing lining is made of special section and has the shape of a back arch special profiles 6j by means of which the upper side interacts with the upper element 7 of the fixed lining 8, to the upper I there are rigidly attached to the upper I the lugs 2, which have lugs 9 with 10 o holes in the lower part. Through the holes 10 air 9 inserts the clip II, which grips the head 12 g hydraulic stand 3 in its narrow part and keeps the hydraulic stand 3 from falling when pressure is lost in it,

Such a connection of the rack 3 with the stop 2 also allows installation. It is angled to the horizon. To the outer side wall of the anvil 2, a film 14 is installed by means of a bolt 3, which rotates freely around the bolt I3 and fixes the bracket to prevent it from falling out. In the base, to the hydraulic pillars 3, supports 4 are attached, having a stand with a spherical protrusion in the lower part. For fixing between the oblique walls of the end part of the hydraulic stand and the vertical inner wall of the support 4 of the post, two half rings 15 are attached, which are attached to support 4 by means of bolts 16 A rack 3 with a support 4 installs 3 sphere 17 of an expanded plate 5. Broadened plates 5 have a handle ™

The chains I8j with which the chain links I9 are connected when the hydraulic columns are located at an angle to the horizon and in the presence of a slip between the broadened plate 5 and the working soil. To reduce slip, the outsole of the wider support is provided with spikes 20.

The connection of the hydraulic pillars 3 with the top I by means of the stop 2 and the bracket j and also with the broadened plate 5 by means of the supports 4 with a spherical protrusion makes it possible to position the stands at an angle to the working soil of the horizon). This kind of

The position of the posts is necessary when there is a pipeline in the working or a friend, their mechanisms, as well as to ensure more effective coping. tivleniya reinforcing lining forces gor-.

foot pressure.

For installation, reinforcement lining connects hydraulic pillars 3 with supports 4 by means of half-rings 15 and bolts 16 .. as well as hydraulic

Stand 3 with top I with staples 1 I “Then the hydraulic stands with top are lifted and installed into the spheres 17 of the wider plates 5 laid on the working soil. The supports 3 are moved apart by a manual pump,

The built-in inside of each of them, to the required height, is joined by a special profile of 6 mirrors and ka. with the top 7 of the permanent lining 8 and bursting with a certain initial effort thrust. Under the influence of mountain pressure, the load on each hydraulic rack increases to the working resistance.

(25 ts 5 after which the pre-relief valve is actuated. With this, the hydrostroke provides some compliance with a constant resistance of 25 ts.

Reinforced lining is installed, for example, when re-using the mine immediately after lava. After intensive displacement of the collapsed roof rocks when rock pressure

The holding output is stabilized; the reinforcements are removed, transferred to the clearing face and re-installed immediately behind the lava.

The use of reinforcing lining will allow you to install and loosen it, do not remove the support and interframe structures of permanent lining. Along with a reduction in the laboriousness of installation and cleaning

312

The reinforcement support improves the condition of the support, as the interframe straps are not removed, thus the support is not weakened.

The use of hydraulic racks in reinforcement krep x provides a higher initial resistance and a quick exit lining on the working resistance.

32094

The reinforcement structure was designed in such a way that it allows the use of serial hydraulic stands without any constructive modifications.

The use of reinforcement supports provides more than three times the increase in resistance and support in the support development.
