The invention relates to the field of mining and can be used in the processing of thin gentle and inclined seams with undercutting and leaving roof or soil rocks in the developed space.

The aim of the invention is to provide selective mining of undercut and left formation in the developed space.

FIG. 1 shows a cleaning mechanized complex in lava, a plan view;

in fig. 2 - the same, view from the developed space; in fig. 3- section A-A in FIG. 1 with an embodiment of the downstream branch of the conveyor open from the bottom; in fig. 4 - section bb pa fig. 1 when the steam tank is discharged from a curtain-sided conveyor with sectional bottoms,

The cleaning mechanized complex includes sections 1 of the support, connected by hydraulic jacks 2 of movement with a scraper conveyor having a flexible traction body closed in the thorium plane with a bottomhole 3 and a bulk 4 branches located respectively under the bottomhole 5 and bulkhead consoles 7 sections I. The length of the bulkhead consoles of the overlap of a larger sum of steps for the frontal gearing: the sections of the powered support and the width of the idle branch of the conveyor.

Za.ena on branch 4 of the scraper conveyor is located above the working soil and is connected to the soil-boring silt 3 intersection beams of 8 G-shape, installed by the larger shelf 9 on the soil and directed by a fencing board. (smaller shelf) in the direction of the roof and goaf. The scoop 1 branch 4 of the scraper conveyor is fixed on the upper part of the guard-Hi shchigov 10 from the side of the open space.

Barriers 10 are telescopic, and their sliding parts 11 are provided with fixing elements 12.

The fencing panels are equipped with hydraulic jacks 13 of the separation, designed to move their sliding parts and the charging branch 4 according to the thickness of the formation. The zaval'ny branch on the side of the roof has limiters 14, providing a guaranteed clearance between this branch and the overlapping of 7 lining sections.

An excavator 15 (narrow-grained combine harvester) with adjustable working bodies 16 is installed on the face conveyor 3 conveyors.

The conveyor section 17, coupled with the traffic drift, is made with a controlled sectional bottom 18, which provides the lower unloading of the transported mass and its supply to the drift loading crane 19. The bottom is controlled by means of a hydraulic jack 20.

The scraper conveyor branch may have two versions.

When first performed, this branch has sidewalls 21 and is made open from the bottom; in the second, it is equipped with sectional side plates attached

bottoms 22 mounted rotatably in a vertical plane and connected by means of hydraulic jacks 23 of control with protective shields

ten.

The scraper conveyor is equipped with two drive 24 or one drive and one tension 25 heads (stations) located on drifts or associated with lava workings.

The complex is placed in an assembly chamber, traversed with the cutting of soil or roof rocks. The power of the cut rock layer during the mining operation is based on the condition that the size of the wellbore space is sufficient for efficient operation and maintenance of the mechanized complex.

0 When mining the reservoir, the excavation of the mineral and the native layer is carried out separately in time, and the layer that is higher is first removed, for example, during the lower demolition

5, the formation is first removed, after which the soil is sown, at the top, the roof is cut off first, then the formation is excavated.

When the reservoir is ahead of excavation, the machine 15, moving along the lava along the downhole branch of the scraper conveyor, by the working bodies 16 destroys the reservoir to its full capacity and immerses the mineral in the bottomhole branch 3

5 conveyors. The mineral branch is transported by the downhole branch to the sectional bottom 18, which is in the open state, through which it enters the drift loader 19.

0 Following the passage of the excavation machine

the sections 1 are shifted by lining, which, by means of the downhole supports 5 of the floors 7, fix the exposed roof.

5 After the coal has been excavated over the entire length of the lava and discharged onto the material handler, the sectional bottom 18 with the hydraulic jack 20 is closed and the working bodies 16 of the excavation machine are adjusted for power

0 cut soil. In the subsequent reverse course of the excavation machine, the soil is cut by a selected amount and the damaged rock is loaded onto the downhole branch 3 of the conveyor.

5 Depending on the accepted pattern of rock unloading in the worked out space 1, the armoring branch of the conveyor transports the rock in the direction of either the haulage or the vent. Crawling around the drive 24 or tension

25 stations, the rock enters the intake branch 4 of the conveyor, which is pulled out by the hydraulic jacks 13 together with the sliding parts 11 of the intersection beams 8 to the extreme upper position, up to the rest stop 14 in the overlap of the lining sections.

The thickness of the rock layer discharged into the worked-out space can be changed by adjusting the amount of elevation of the downstream branch of the conveyor over the working soil,

In the case of the ignition vetap of the scraper conveyor open from the underside, the incoming rock is discharged down onto the working soil. As the layer of the discharged rock on the soil increases to a value equal to the distance to the curved branch of the scraper conveyor, the rock unloading zone moves sequentially along the lava, and the rock is transported along the curved branch to the discharge point through the laid rock layer.

If the embedment branch of the scraper conveyor is made with sectional bottoms 22, the rock that enters this branch is transported to the last of them, which is open, and is unloaded, filling up the excavated space below the embankment branch. All other sectional bottoms should be closed. As the rock is unloaded, the layer of rock on the soil increases, and after filling the entire space between the soil and the scoop conveyor branch in the area of the open sectional bottom, the discharge through it stops. By this moment, the sectional bottom, adjacent to it, should be open, through which the rock unloading into the developed space will be continued. The place of rock unloading from the downstream branch of the scraper conveyor is sequentially moved from the last sectional bottom to the first, which corresponds to the movement of the combine along the entire length of the lava.

The opening of each next sectional bottom is made automatically, and the signal for opening can be supplied by the excavating machine, depending on its position on the downhole branch of the scraper conveyor or rock, according to the filling level of the open space in the area between the soil and the embankment branch.

After completing the breeding rock and unloading it into the developed space, the scraper conveyor by means of hydraulic jacks 2 is moved a step equal to the capture value of the excavation machine, the latter is hacked into the formation, and the described sequence of operations is repeated.

Scraper conveyor branch

Constantly throughout the entire cycle of works, under the protection of the dammed consoles of b-covers of 7 sections, which is achieved by the above choice of its Length.

If dredging is done with

Before the rocks of the roof, then first remove the rock layer, then the coal seam. The nature of all the operations performed remains unchanged.
