The mining-transport complex is presented in figure 1 - plan figure 2 - site mounting of the scraper to krupasindhu circuit double circuit of the traction unit at a horizontal arrangement of the scraper, figure 3 is a transverse section through the carrying branches in the middle part of the complex, in figure 4 the same in a transitional curvilinear plot on figure 5 is the same in the zone of crowding of traction on the drive sprocket.

The complex contains infinitely closed in the horizontal plane two-traction body, with the standing of the two kruglozernyh circuits 1 and 2 with attached scrapers 3 rectilinear profile in the transverse relative to the rod conveyor direction, drive 4 and terminal 5 stars with the possibility of rotation, panline 6 and 7 for carrying and outside branches of the traction unit. Each scraper 3 is placed on the horizontal links 8 kruglozernyh circuits 1 and 2 of the traction unit with the possibility of interaction of the notches 9 of cylindrical shape on Skrepka 3 with a straight section of the wire forming the link 8 chain on his prodiamine. Scraper 3 with removable polovchak 10 is fixed on the outside with respect to the longitudinal axis of the conveyor part link 8 chain with the possibility of rotation of the scraper 3 on it. Panline 6 and 7 in the zone of adjacency to the drive 4 and the terminal 5 stars made with a curved transition sections 11, 12 and 13, 14 with the transition from flat to flat horizontal vertical location directly in front of the drive 4 and the terminal 5 stars. The outer edges of the scrapers 3 by panline 6, 7 in the vertical plane is made curvilinear 15 with the possibility of their interaction with curved surfaces 11-14 panline 6, 7 on transient sites. Scrapers 3 by panline 6, 7 are made with openings 16, the height of the neck 16 from the center of the horizontal links of the 8 circuits 1 and 2 adopted by more than half of the width and level 8. Scrapers 3, located on the site equal to the length L of the conveyor, made with naru the hand relative to the longitudinal axis of the conveyor and oriented perpendicular to screencam 3 risers 17 in the form of beams of equal resistance in mutually perpendicular planes. On the risers 17 fixed removable cutters 18, oriented away from the longitudinal axis of the conveyor, the height of the cutting edges of the cutters 18 and their location on the height from the upper surface of the scraper 3 is determined from the formula

where b0- the height of the cutting edge of the lower cutter 19, i is the number of cutter 18 located above the lower cutter 19, bi- the height of the cutting edge of the first cutter 18, n is the number of cutters 18, located above the lower cutter 19, b1the height of the cutting edge of the first cutter 18 located above the lower cutter 19, m is the capacity of the mined seam fossil, h1hi- the excess of the middle part of the cutting edge respectively of the first and the i-th cutters 18 above the upper plane of the scraper 3. Thus the total height of the cutting edges of all of the cutters 18 and 19 is equal to the thickness of the mineral, and the location of the scraper with 3 cutters 19 and 18 along the length of the conveyor taken step increments between the cutters l=L/n with increasing height hithe location of the cutters 18 on 3 pigs in the direction opposite to the direction 20 of the movement of the traction unit.

The height of the b0the cutting edge of the lower cutter 19 is selected to provide the Stripping zone at the base of the reservoir and the height of the b1the cutting edge of the first cutter 18 and the height h1placing it over ver is it a plane scraper 3 is selected from the conditions of ensuring the strength of the attachment of the riser 17 with the cutter 18 to the scraper 3.

The above ratios of the settings of the attachment points of the cutters 18 to screencam 3 are derived from the condition of equal stress on the attachment points, regardless of the height placement of the cutters 18 on scrapers 3.

All scrapers 3, equipped with cutters 18, opposite to the cutters 18 side provided with an additional vertically oriented struts 21 of the same height, with the possibility of their interaction with the vertical flanges 22 panline 6, 7 as carrying on, and outside the branch conveyor. The surface of the additional struts 21 from the side boards 22 panline 6, 7 is covered with a layer of antifriction material. 23 is a vertically oriented links kruglozernyh circuits 1 and 2 of the traction unit. 24 - bottom breast. 25 - bolt connections.

Downhole mining-transport complex functions in the following way. In the initial position of the system using the driving devices (not shown) is close to the bottom 24 of the branch of the traction unit, which is free from the cutters 19 and 18 on 3 pigs. When enabled, the drive sprocket 4 a driving force is transmitted to the traction body, made of two kruglozernyh circuits 1 and 2 with 4 horizontal and vertical 23 links and mounted on a horizontal units 4 scrapers 3. When the movement of the traction unit by panline the rod 6 in the direction of 20 teeth on the other with the bottom 19 and then the cutters 18, attached to the risers 21 scrapers 3 step l, layer by layer starting from the bottom layer when exposed to the bottom breast 24 destroy it, and separated from it the rock mass is overloaded in the panline 6 and transported it scrapers 3 section panline 6 with a horizontal transverse profile in the direction of the drive sprocket 4. This scrapers 3 first occupy a horizontal position (figure 2), sliding on the outer surface of the panline 6, and the vertical links of the chain 23 of the traction unit are moved with clearances above the surface of the panline 6. Simultaneously with the haulage is provided scraping bottom protruding edges of the scrapers 3. The longitudinal force caused by the resistance to movement of the rock mass and the scraper 3 and the load associated with the destruction of the breast bottom 24 and simultaneously scraping the bottom of the cutter 19, perceived vertical links of the chain 23 of the traction unit, in which abuts scrapers 3 during their movement by panline the rod 6. At the approach to the drive sprocket 4 scrapers 3 enter the zone of contact with the curved surface of the transition portion 11 and gradually begin to rotate in a vertical plane, interacting with their curved edges 15 with a curved surface of the transition section 11 panline 6. Turning parts, all specifications the scraper 3 is relatively outer end of the horizontal links 4 (figure 3). However, the links 4 and 23 of the traction unit do not change their position in space. Directly in front of the drive sprocket 4 scrapers 3 occupy the upright position (figure 4). In this position the drawbar organ 1, 2 with scrapers 3 around the drive sprocket 4 minimal radius of the location of the center of mass of the chain transfer body 1, 2 with scrapers 3 from the axis of rotation of the drive sprocket 4. This allows to limit the speed of movement of the traction unit 1, 2 with scrapers 3 and increases the reliability of the pipeline. With the passage of the traction unit 3 with scrapers 6 through the transition portion 11 is provided unloading of the rock mass in the receiving device (not shown). At the gathering of the traction unit with the drive sprocket 4 scrapers 3, moving within the transition area 12, from a vertical position gradually in the horizontal and the panline the rod 7 outside branches move towards the end of the 5 stars. The process of rounding drawbar organ 1, 2 with scrapers 3 limit of 5 stars similar to those described above. After reaching the first scraper 3 with a minimum height position of the lower cutter 19 complex drive units (not shown) again shifts to the chest of the face 24 on the depth of the cutters 19 and subjugated them cutters 18 and technological cycle excavation and transportation g is nuclear biological chemical (NBC mass is repeated in the order described above. When the complex load perceived by the cutters 19 and 18, is transmitted through the struts 17 scrapers 3 and secured to the struts 21, which in turn rest against the side 22 panline, slipping them at a reduced coefficient of friction due to the execution of struts 21 with antifriction coating in the zone of their contact with the flanges 22. Due to appropriate selection of the height of the bicutters 18 and a height of hitheir placement above the scrapers 3 loads on the struts 21 and scrapers 3 regardless of the location of the scraper 3 with the cutter 18 along the length of the rod conveyor are equal in size due to the different heights of the bisequentially placed along the length of rod cutters 18. The design of the mount scrapers 3 to 4 links kruglozernyh circuits 1 and 2 allows for minimal labor to perform as a replacement scraper 3 and the separate parts of the traction unit during operation of the complex.

Features of the invention provide the possibility of using the scraper conveyor not only as a transporting device, but also as an extraction device for high performance complex by increasing the width of the panline scraper conveyor and under the same loads on each node mounting cutters to Skrepka that p which increases the reliability of the complex.

At that, on the shaft ends there rigidly fixed are drive sprockets for transmitting rotation to the shaft through flexible chain connections from even number of electric drives, and in the middle of the shaft there rigidly fixed are drive sprockets for the conveyor pull chain drive. At that, on horizontal links of the pull chains there rigidly fixed are drag bars at a distance of 200-300 mm from each other. Metal plates are hinged to the drag bars from above and form a flexible hinged metal transportation belt with friction factor of 0.15.

EFFECT: developing reliable design of drag conveyor, which allows transportation of loose and plate materials for up to 2 km and more with the angle of slope of loose material transportation plane up to 40°, and increasing capacity up to 1500 t/h.

SUBSTANCE: in complex based on horizontally closed scraper chain a traction element is arranged as double-chain. Scrapers at side external relative to longitudinal axis of conveyor and at the length of contour equal to length L of the conveyor are arranged with stands perpendicularly aligned to scrapers in the form of beams with equal resistance in mutually perpendicular planes. Detachable cutters are fixed on stands, being aligned aside from conveyor longitudinal axis, besides, height of cutter cutting edges and their location along height from upper plane of scrapers are defined based on mathematical ratios. At the same time total height of cutting edges in all cutters is equal to capacity of mineral bed, and location of scrapers with cutters along conveyor length is accepted as stepped with pitch between cutters l=L/n with increasing height of cutters location on scrapers hi to the side opposite to direction of traction element movement. Besides, height b0 of cutting edge in lower cutter is selected on the condition of providing zone cleaning near bed foundation, and height b1 of cutting edge in the first cutter and height h of its location above upper plane of scraper are selected on the condition of providing strength of unit for fixation of stand with cutter to scraper. All scrapers equipped with cutters, at the side opposite to the cutters are equipped with additional vertically aligned stands of the same height, with the possibility of their interaction with vertical boards of panline both at weight-bearing and idle branches. Surfaces of additional stands at the side of panline boards are coated with a layer of antifriction material.

EFFECT: using scraper chain both as transportation device and a mining device.
