The invention relates to mining, particularly to a mechanized systems for longwall mining.

Known cleaning mechanized complex in which the shield support is not the one with the face conveyor, includes sections of powered roof supports, containing slabs, fences, hydraulic jacks, which are interconnected through the brackets on the ceiling swivel spotboy communication and jacks of movement, each section is equipped with associated with focusing mechanism changes the attachment of the Jack of movement of the slab; the AFC includes a head actuator on the conveyor and supporting the ventilation drifts and positioned between rod with linear pans pivotally connected locks. Each trough is provided with a place to lock jacks shifting, custom by moving from a focus from the front legs of shields (1).

The disadvantage of this complex is the limited scope of powered roof supports, both because of the complexity of its management, and small range of mechanism to change the attachment point for jacks of movement of the sections, which limits its use at various angles razdiakonova line stope (OZ) with directional movement along the strike. No constant is Oh kinematic relations lining with the face conveyer increases the complexity of its operations, shifting and hold the removable strip. On the layers gently drop it uncompetitive with complexes, where the support and the conveyor are one.

Known cleaning mechanized complex consisting of powered roof supports of the individual line sections together through the AFC becoming which consists mainly of linear pans with interlocks between them (2).

The disadvantage of this system is the impossibility of directed motion along strike at different angles of inclination of the line OZ for fall, especially inclined steeply. Persistence point displacement downhole loading point on the gathering conveyor allows to ensure the completeness of the extraction of coal reserves and a steeply sloping shallow coal seam preserving directional move of the complex.

As the prototype accepted treatment mechanized complex (OMC), which is widely used on the seams flat and oblique incidence in long LAKE during the development system "Long poles along the strike" design of powered roof supports, the AFC urchinsky machinery (3) and the displacement of angiomas (4) or complex "joy" and others with the item remounting with the use of special tools.

The complex consists of:

from shields to the base, fence, roof bar, trump is om, gate, hydraulic jacks, hydraulic Jack of movement with the plunger and remote control in the form set;

from conveyor with head drive on the conveyor and supporting the ventilation drifts and located between rod with transition sections and line pans pivotally connected locks.

Each pan is interconnected with Jack advancing shields constant communication node of the lugs on the pan and pusher with earring Jack advancing.

The disadvantage of the OMC is its inefficient use, inability directional movement along the strike of the formation at various angles of inclination of the line stope and the lack of means, including remounting.

The purpose of the invention is to enhance the effectiveness of the OMC by providing a directional move at different angles of inclination of the line stope, as dip and along strike of the formation, and self-sufficiency for the remounting of demolition in the mounting chamber.

This goal is achieved by the fact that the OMC for excavation of the reservoir in a diagonal line stope with devices remounting, including mechanized lining of the sections containing the base with the plunger of the Jack movement, fences, floors with visors, the AFC containing the th pans with lugs the head actuator, downhole displacement, characterized in that the OMC fitted units, three with Autonomous control panels and mechanism of movement type RCC - rasprostertymi-sliding when remounting complex, elongated side part of the fencing device tuck visor shields, the mechanism of interaction changes the attachment sections to the conveyor cylinders regulation at various angles of inclination of the line stope, when mining pillar in the range from -45 to +45 degrees, with the same location of the AFC with respect to the displacement of the rock mass on the downhole loading point.

The mechanism of interaction changes the attachment of the Jack movement to the conveyor made in the form of articulated spotboy communication containing perforated holes sheet guide fixed to the pan, and rolling of the tongue-mounting bracket with a fixed tongue-fence, interconnected by a control cylinder with the possibility of mutual regulation. Tongue-and-groove pre-punched guide holes may be removable from the mount through the eyes of a trough her eyes with a finger, and, as an option, tough as one piece with the pan.

The movable tongue-bracket provided with holes for interconnection with an earring pusher Jack of movement and for the cylinder reg is the regulation on the protruding part and the hole for fixing with necessary inside a perforated guide.

A still tongue-emphasis provided with a hole with your finger for mounting the control cylinder and xation holes in the perforated guide when moving the tongue stops.

The fence of shields made with regard to the maximum displacement of adjacent sections when the maximum diagonal line stope. The plunger of the Jack movement made sliding locking required length, through the holes with your finger and as an option with hydropattern visor overlapping shields from the chest bottom is equipped with a mechanism razdiakonova considering changing the position of the line stope and made in the form of sliding plates, interconnected front hinge sliding spotboy frame with the possibility of extension of the hydraulic cylinders pivotally interconnected with spotboy frame-rail and visor, and the grooves of the hinge plates. Tongue-and-groove frame is provided with a hinged-hinged apron holding his chest face with the hydraulic cylinder interconnected with apron and visor by means of spherical bearings.

Shield with pans kinematically and hydraulically (hydrochem) performed in blocks (three) with a single remote control and the possibility of movement without spreading out in dismantling the camera and remounting, with movement in mounting the camera unit (triples), its course, according to the scheme IU is anima movement type RCC - rasprostertymi-sliding and running in the plane of the reservoir cylinders regulation.

Figure 1 shows the OMC in the face with ahead of the bottom view in figure 2 is the same when ahead of the upper part of the lava; figure 3 - block of three sections in the linear part of the OMC figure 2; figure 4 is a section a - a in figure 3; figure 5 is a view B figure 4; figure 6 - section b In figure 7; figure 7 is shown a visor in the plan.

Cleaning mechanized complex (OMC) consists of sections 1, United into one through hole 2 of the pipeline.

Section 1 consists of (3) from the base 3, fences 4, roof bar 5, the visor 6 with a sliding gate, the legs 7, jacks of movement 8, pusher with an earring 9. Face conveyor 2 consists of the head actuator 10 on the conveyor and auxiliary 11 on the ventilation drifts (Fig 1, 2) and located between the rod of the linear trough 12 (figure 3) with a locking connection between them (not shown).

The shields are connected with the rod AFC mechanisms of interaction with the attachment of the pusher with the earring jacks of movement with the pans.

The mechanism of interaction with changing the attachment of the pusher Jack travel to the pans are made (Fig) in the form of articulated spotboy communication in the form of a perforated spotboy guide 13 fixed through lugs 14 each R is the few industrial environments 12, and the tongue-mounting bracket 15, pivotally interconnected through the eye with an earring by a pusher 9 and the hydraulic regulation 16.

Cylinder regulation one end (e.g., a cylinder) is attached to the tongue-fence 17 with holes for fixing the position in spotboy guide 13 through the perforated holes.

The pusher 9 is made sliding-shaped locking retractable part through the perforated holes relatively retractable 18 removable finger, it is possible (as an option), as hydropattern (not shown).

Fences 4 shields are made with side walls 19, the width of which overlaps the magnitude of the displacements of the adjacent sections at the maximum razdiakonova line stope (for example, 45 degrees), excluding the penetration of collapsed rock mass of the blockage in the working area of the complex.

The block of three sections and three pans have Autonomous control unit 20 mounted on the secondary support units in the block.

At different angles of inclination stope 21 the tongue-mounting bracket 15 is the correct position, which is achieved by the control cylinder 16.

The visor 6 with a sliding gate valve 22 allows to pick up the roof, naked in the zone of razdiakonova in the form of a triangle, with simultaneous pressing of the breast slaughter due to the hinged apron 23 with the cylinder 24. The gate to perform the Yong from a set of plates 25, borrowed through the grooves 26 with a sliding spotboy frame 27.

Tongue-and-groove frame at the ends pivotally interconnected with the cylinders 28 of the gate, located under the visor 6. Because of the complex reciprocal movements of the cylinder 24 with the apron 23 and the visor 6 is equipped with spherical bearings 29, 30 with crackers and flanges (not shown).

In the initial position the jacks of movement 8 reduced section 1 are parallel to the conveyor gate 20 ledges in the plane of the layer.

After excavation of the next strip and coal belt conveyor move the shield as a unit, or separately, pre-relieve the hydraulic jacks 7 on the shields, tighten them jacks of movement to the face conveyor, pumps vernaci 5 in the top of reservoir with hydraulic jacks 7, and so on throughout the length of the lava. Then the cycle repeats. When changing the angle of incidence of the reservoir relative to its stretch, the angle of the line stope relatively (e.g., conveyor drift 20) is changed by adjusting the attachment of the pusher Jack of movement in the mechanism changes the attachment Jack regulation 14. The same is with the approach of the lava to the place of removal, where the line stope is formed in parallel revealing mining.

This OMC will allow complete extraction of the coal in the coal on the reference layer with the scheme of developing the mine-lava", "mine-layer" long poles along strike.

Due to the directional movement of the shields in parallel conveyor roadway in conjunction with downhole conveyor provides a constant point of displacement on downhole loading paragraph 31 without bias gate conveyor (conveyor, belt conveyor) relative to its axis.

When the diagonal stope ±45 degrees allows you to increase the scope of application of the OMC by reducing ground pressure on the shield due to the formation of the maximum dome in the zone of collapse behind the middle part of a long lava that will lead to the reduction of metal OMC with simultaneous orientation in a favorable position, and the line of cleavage with the formation of the sustainability of the breast slaughter capacity of the reservoir, without any additional special tools. The opportunity downhole loading point to be made directly on the telescopic belt conveyor without the loader, due to the displacement of which the conveyor belt increases the height of the conveyor drift along the entire length, decreases the intensity of vehicles from under the lava stope. You can manage three (or blocks) of the control cylinder of the mechanism of interaction of shields with the pans of the conveyor sufficiency set the KSA when remounting, reduce the time of Assembly and dismantling.
