With the creation combines the above-described structures, it becomes possible to improve the way the notches of formation of minerals, particularly coal and rock inclusions fortress f>8 in optimal conditions. The improvement of the method consists essentially in the use of at least one of the two working in one lava harvester according to the invention with the Executive authority, designed to work on a strong rock inclusions, equipped with mechanism for feeding the handle on the bottom and a device for keeping combine motionless when blasting rock inclusions Executive body.

Below is a description of the method of extraction of coal from the proposed design combines with reference to Fig-17.

Circuit testing of lava with a different location of strong rock inclusions along the length of the reservoir is presented on figa, b,,,

In the initial position (Fig,a) harvester 87 according to the invention is located at the right mate and is designed for excavation of the reservoir at site L2 with rock inclusions of length L4, the right handle 15 is equipped Executive body 23 for destruction of rock inclusions. Harvester 88 of known construction is levov the pair and is designed for excavation of the reservoir at site L1, mostly free from rock inclusions, and the handle 15 is equipped Executive body 16 for blasting coal.

Excavation cycle combines both begins with the notches in the seam skew the race, while the harvester 87 as well as the harvester 88 carries out a notch in the reservoir at site L3, free from rock inclusions.

On Fig,b, C shows the harvesters 87 and 88 in the process of notches in the seam. After the notches in the seam harvester 87 is located immediately before the section L4 rock inclusions, and the harvester 88 - left pair of lava from the roadway. Then begins working stroke, when both combine 87 and 88 move from left to right in the same direction. Before the stroke harvester 87 enables the device to hold it in a stationary position on the conveyor 9, and then starts the mechanism for feeding the handle with the Executive body 23. After selecting the inlet of the hydraulic Jack mechanism for feeding the handle off device for keeping combine 87 and includes the mechanism for translational movement of the harvester 87. When this happens, the breaking of the undestroyed part of the layer remaining after the passage of the Executive body 23, and loading smitten rock mass on conveyor 9. In operation, the mechanism for moving the harvester hydraulic Jack mechanism for feeding the handle is folded and whom the ain 87 is prepared for the next cycle of destruction plot L4 rock inclusions on the magnitude of the stroke (800-1000 mm) hydraulic Jack. Next, the above operation of the stroke are repeated until the end of the cycle excavation at site L4. After that, the harvester 87 on shunting speed is returned to its original position, shown in Fig,and. Harvester 87 produces dredging coal at site L1 is known chelnokova schema.

In the event of displacement of the rock inclusions in the layer to the left pair, as shown in Fig, produce the conversion harvesters 87 and 88: combine 87 then becomes available as a standard version, as the harvester 88, and the harvester 87 will be redesigned according to the invention. Now the harvester 88 works at site L5 like harvester 87 on the section L2 (Fig,a), destroying the rock inclusion on the site L7, and the harvester 87 produces the excavation of minerals at site L6 known chelnokova schema.

If rock inclusions occur in the middle of the lava, as shown in Fig, both combine 87 and 88 are equipped in accordance with the invention. In the case of mining waste rock inclusions harvesters 87 and 88 are working on a unilateral scheme with the movement in the operating mode to meet one another, and mining minerals in areas free from waste rock inclusions, chelnokova scheme with the notch on the beneficial minerals that is coal.

In the case where the power of rock inclusions bigger than the exterior diameter of the Executive body 23, vtoro the Executive body 16 can also be replaced by the Executive body 23. When this loading is smitten rock mass is mainly produced wiper plowshare of the conveyor 9 in the process of shifting to the new road.

SUBSTANCE: combine has main body, drive, feeding mechanism and executive tool, which is made in form of drum with horizontal rotation axis. It is placed at non-straight angle to longitudinal conveyor axis and is turned in horizontal plane in direction providing for displacement of trajectory of coal output towards conveyor. Drum has cylinder, on outer surface of which in certain order cams with cutters are fixed. Inside the cylinder three or five electric engines are placed. These are inserted in parallel in recesses of fixed body with inner teeth of sun ring of planetary gear, which interact with three satellites. Output shafts of three or five electric engines interact with one common cog-wheel. It is placed coaxially with planetary gear and engaged with it by torsion shaft having two cog tail pieces. One of tail pieces interacts with inner slits of wheel hub, and another interacts with teeth of three satellites of planetary gear. Mechanism for hoisting drum mechanism along bed massive has handle raising jack and handle with horizontal rotation axis placed in horizontal plane at non-straight angle to conveyor axis and turned to direct displacement of executive tool towards pit-face. Shoes of stability mechanism for combine are provided with reverse clamps for shelves on front pit-face and back dump sides of conveyor. Back support of conveyor on soil is placed on dump end of inter-section beams. Combine feeding mechanism has drive for chainless feeding system and leading sprocket. Sprocket interacts with fingers of conveyor rack. Drive is placed beyond handle of executive tool and is made in form of separate electric engine with reducer of self-braking worm type. Engagement of sprocket with fingers is guaranteed by reverse clamp of reducer engaging back planes of conveyor rack carrying these fingers. In method for loading coal on conveyor, drum rotation axis in plane around vertical axis is turned in certain direction to turn trajectory of coal towards conveyor. Movement of mining drum along conveyor is performed first along ceiling, and then along soil along coal output direction while providing for cleaning of soil in direction of frontal movement of conveyor to pit-face.

EFFECT: lesser dimensions, lesser mass, higher quality of operation.
