The invention relates to mechanized means of fixing of mining faces in the mining industry.

The aim of the invention is to increase the efficiency of the support when working out powerful inclined and steep layers by increasing stability, controllability of the support sections and reliability.

FIG. 1 shows a cleaning complex with the proposed lining, general view; in fig. 2 view A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 is a cross-section of the FIG. 3; in fig. 6 is a section DD-D in FIG. four.

Mechanized mountain-support for mining by the posts on the uprising with laying of steep and inclined layers includes sections, each of which contains base 1 and top to 2, connected by hydroresistance 3. Top to 2 is made of two or three parts, interconnected by joints and hydraulic cylinders 4. The downhole console 5 is telescopic and is equipped with a telescopic shield b for fastening the coal mass. The rear console 7 is necessary when working with the bookmark and is also telescopic. The rear console 8 of the base 1 is necessary when working with a bookmark of a goaf to support the bookmark. A hydraulic post can be installed between the rear consoles 7 and 8 of the upper 2 and the bases 1 (Fig. 1-4).

All sections of the support are connected with the links of the base by hydraulic cylinders 9 of moving the tops 2 and bases 1.

Each link 10 of the base is made of two trusses with spacer links 11 and 12, mounted one above the other in height and rigidly interconnected by horizontal shelves (frames) 13 and 14. Vertical shelves 15 and 16 of link 10 of the base are made of upper and lower telescopic links, which are located on opposite sides of the horizontal shelves, are connected to the latter by means of

The links 11 and 12 are moved apart and contracted by hydraulic cylinders 17 and connected to the tops and bases with kinematic translational pairs. The supports 18 of the telescopic vertical shelves 15 and 16 are provided with sliding parts 19, which, with their sliders 20, fit into the longitudinal guides (slots) 21 of the upper 2 and bases 1. The sliding parts 19 move by transverse hydraulic cylinders 22 moving, which are fixed to the sliders by one ends 20, and others - on the supports of 18 telescopic links.

Each base unit 10 has devices 23 for connecting it with an adjacent base unit along the support, which are located on horizontal 13 and 14 and on vertical 15 and 16 shelves. Double connections 23 on horizontal shelves 13 and 14 ensure the reliability of the connection of the links 10 of the base between them and the possibility of repairing them without stopping the complex. Each link 10 of the base has a bottom downhole loading telescopic console 24 provided with a bottom hole telescopic shield 25 for securing the coal mass in the lower part of the formation. A conveyor 26 is installed at links 10 of the base for transporting coal or other minerals along the bottom. The links 27 of the combine 28 are mounted on the links 10 of the base, which provide coal extraction and loading it onto the conveyor 26. The power supply of the combine 28 is carried out with the HELP of the cable layer. Cable guard placed on the upper farm.

Installation and disassembly of the mechanized support complex is carried out at the minimum structural height of the support and base sections.

The device works as follows.

FIG. 1-4 lining shown in the original position. The operation is the movement of the base together with the combine 28 and the conveyor 26 - the notch of the combine. From the sections supported in the lateral rocks, the base is moved by the hydraulic cylinders 9 of displacement per step of movement. In the zone of the combine 28, the face shields 6 and 25 are folded, in the other zones the bottom faces are attached. As the base moves, the bottom face consoles 5 and 24 are reduced.

The second operation in the excavation cycle is the movement of the lining sections, which are alternately pushed by the hydraulic cylinders 9 to the base. The movement operation of the sections may be combined with the coal cutting operation by a combine or independently. The combine moves the feed part along guides 27 at the base of the support along the supports from one flank to the other. By removing the coal ribbon, the excavation cycle ends and a new cycle begins in the same sequence.

Due to the connection of the telescopic vertical shelves 15 and 16 of the base with the upper 2 and bases of the 1 section, lining kinematic pairs and hydraulic cylinders 22 in the process of sliding the base (including turning) hydraulic cylinders 9 can be displaced along the side of the hydraulic cylinders 22, which dramatically increases the maneuverability of the lining and the performance of the complex. The hydraulic cylinders 22, hydraulic legs 3 and the connections of the sliding parts 19 with the top 2 and the base 1 allow, during the movement of the sections, to control the angular and linear displacements of the bases and the top in two planes, which increases the efficiency of the support movement control and the performance of the complex .

Telescopic shelves and their connection with tops and bottoms allows the bases to be raised and deployed to overcome significant (at least 300 mm) obstacles (ledges) in the soil of the reservoir. With the unzipped sections, the presence of kinematic connections of the base with tops and bottoms, which allow displacing the bases across the tops (along the bottom), provides the base

The supports not only have increased steerability on steep seams, but also increased base reliability with gaps between the links. When the connection of the links of the base is broken (destroyed), they are consumed and, in the absence of a controlled movement of the base along the bottom, the connection operation becomes long and laborious. In the proposed support, the reliability of the base is increased both due to the duplication of the connections, and due to the possibility of their quick connection with high maneuverability of the base (its parts).
