Abstract

Use: extraction of minerals paired lavas with one redeemable transport output. SUMMARY OF THE INVENTION: The lining contains two extreme sections, between the bases of which a loading crane is installed, the bases are made of separate segments with guides. On the bases, with the help of carriages, drives of lateral conveyors are installed. The outermost sections are connected with the loader by the movement mechanism. The latter contains two flexible connections, each in the form of a horizontal loop, laid in guide bases, and two pairs of hydraulic jacks. One pair is connected to the bases and the loader in the bottom of the support. Another pair is located in the downhole part of the lining and is connected with the loader and one of the ends of the flexible connections. The other ends of the flexible connections are fixed on the downhole portions of the bases. 3 il. cl

Description

The invention relates to the coal industry, namely to a fixed mate for mining paired lavas.

The aim of the invention is to reduce the metal intensity while increasing the efficiency of the lining operation with changing hypsometry of the soil of the formation.

FIG. 1 shows a mechanized lining of the mating, top view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

Extraction pillars 1 and 2 are worked out by double lavas, in which lava sections 3 and 4 are installed, which are included in the equipment of the mechanized complex. The repulsed coal is delivered from lavas to transport output 5. Conjugation of transport output

5 with lavas supported by mechanized support mates.

The mating is made in the form of two extreme sections. Each extreme securing section is made in the form of a base 6 connected by means of a hydrorack 7 with overlapping 8.

The base 6 is made in the form of separate segments with channels 9, relative to which the flexible links in the form of two parallel branches are oriented. The end of one branch of the flexible link 10 is connected to the base section, through the end 11 of which passes independently the end of the second branch of the flexible link 10. A loading device 12 is located between the bases 6 of the outer sections of the support.

Extreme support sections are connected to the loader 12 with the neVJ mechanism

The movement is made in the form of two pairs of hydraulic jacks of movement.

One pair of sliding jacks 13 is connected to the bases of the bis by supports 14 of the reloader 12 in the lower part of the support support.

A second pair of hydraulic jacks 15 of movement is connected to the loader 12 and to the free ends of the flexible links 10, which are independent of the ends of the 11 segments of the base 6.

On bases 6, by means of carriages 16, drives 17 and 18 are reinforced with a gap between them. Overlap 8 are interconnected by a jack 19 correction. The distance between the hydraulic posts is 7 times the travel of the travel jacks 20.

Mechanized lining mating works as follows.

After extraction of the coal by a combine in the extraction column 1, the drive 17 is moved by the front section 3 and is supported along with the carriage 16.

Then the hydraulic jack 13 of the first pair is turned on, the hydraulic jack 15 of the second pair moves onto the slide and moves the loader 12 along the transport output 5. The hydraulic posts 7 of the left part of the support mate are engaged in reducing and due to the reduction of the hydraulic jack 13 of the first pair and the hydraulic jack 15 of the second pair of left part lining mates relocate this section to lug mating in the direction of advancing the reloader 12

After that, the hydraulic posts 7 are turned on the spread and the left part of the support is spread by overlapping 8 into the roof of the transport exit 5.

The rights part is similarly moved

lining mates.

The adjustment of the overlappings 8 in relation to the sides of the transport output 5 is made by the jack 19

the time of shifting the left or right side of the support mate.
