The invention relates to the field of mining engineering, in particular to mechanical devices for underground mining of deposits of potash are powerful and steep deposits.

It can be used for both drilling Gusenkov, and mining of potash in the floor of the chambers, the height of which is equal to the height of the floor with the formation of the treatment wells.

A device (Starkov L. I., Zemskov, A. N., The Kondrashev P. I. Development of mechanized potash ores. Perm - Solikamsk, 2007, 189-190) containing drilling machine, rotation device, crawler chassis, a motor, a drum for winding the cable operator's workplace. The chassis is a self-propelled crawler track. It consists of a frame, balancers, gearbox, engine, caterpillar trucks, bracket to seat, remote control and manual control.

Despite the versatility of the machine (drilling may at any angles powerful and steeply dipping deposits as ascending, oblique, and down-hole), it is functionally and structurally limited in application: it produces drilling from the bottom up, on a small angle generation (12°), and produces only the preliminary preparation of the well for subsequent extension to the cross section of Gusenkov other machines (mainly Gazenko platform is and).

A device (Starkov L. I., Zemskov, A. N., The Kondrashev P. I. Development of mechanized potash ores. Perm-Solikamsk, 2007, S. 225-231), heading-Shearer, consisting of a planetary type of Executive body, destroying the bottom three rescueme drives, two planetary tabernacle, burkavage body with side cutters and a screw serving to align the soil and cutting corners framing, crawler, carries out the movement of the harvester at work and maneuvering modes. Management mechanisms is maintained by the driver.

The device is not sufficiently maneuverable, carries out the production of ore blocks, implementing a complex scheme of preliminary actions to obtain the ore in the form of blocks and the subsequent action associated with grinding and transportation. Clean the hollow chamber when the development system of underground ore deposits provide the layers with the angle of tilt up to ±12°. It is difficult to manage, works bottom-up, which complicates his work, because it creates a large cutting resistance and the transport of oil in cleaning the well ore. Difficult to reverse combine the roadway after drilling has been completed.

A device (U.S. Pat. No. 2366794, IPC E21B 7/28, from 19.05.2008), including a splined shaft with a removable extender forward stroke on it and guiding light, removable the second extender reverse, consisting of telescopic crosses, and guiding light. Crosses extender made with the likelihood of a rock cutting tool. Smart flashlight is made in the form of a retractable anchor shoes due to the presence of jacks mounted in bearings.

The device is complicated structurally and functionally. It is limited to holding the floor itself excavations for transportation of minerals. The cyclical nature of the work, due to interruptions associated with the change extenders and lights. The device is inefficient when used for sewage extraction of minerals, especially underground chamber method, developed floor to the full height of the floor. The device requires the presence of the labour force that does not ensure the safety of operations.

As a prototype of the proposed device is selected (Starkov L. I., Zemskov, A. N., The Kondrashev P. I. Development of mechanized potash ores. Perm - Solikamsk, 2007, 191-194) as the closest to the technical essence and positive effect. It includes the drifter Gusenkov type PHS-1, the cable winch mounted on the frame in the form of a sheet - skis, unified with the production industry winch, in the kinematic chain which also includes adjustable hydraulic 2 stupenda the first gear with shunting and working gear, the switch which is made by a toothed couplings, and the block through which the hoist rope is connected to the drifter Gusenkov.

The drifter Gusenkov consists of nodes: napravlyayus-spacer device with roller skis, two drive motors, planetary gearbox, outside of the Executive body, internal Executive authority of the sending of the lantern.

External and internal Executive bodies rotate in opposite directions relative to each other. Outer and inner bodies are three-pointed crown with removable beams at an angle of 120° relative to each other, the ends of which are fortified pads with a set of cutting inserts. At the lower end of the shaft of the gearbox on the bearing support reinforced hollow guide light, which the drifter Gusenkov centered on advanced well.

Repulsed cutting ore bodies under their own weight due to gravitational forces, falls into a pilot hole through the through hole in the guiding light.

The device has a limitation in the application: it is used as a device for support, development workings in potash ores (for sinking a vertical or steeply inclined openings, Gusenkov used as the ore chutes, equipped under human is checked, freight lifts, and so on).

The device operates with a workforce of preparatory work, in the process of drilling and during shipment of the ore after the formation of Gusenkov that does not guarantee the security of underground work, increases the risk of injury. Its lack of maneuverability, speed, and accuracy of the institution of the drifter in the face. Controllability of the position of the drifter over the pilot hole is limited to provision of reciprocating movement along its axis in the direction of dip (vertical and steeply sloping, with the involvement of the workforce). The cable is a rope in the complicated connection; after full notches of the drifter mouth of jasenka overlaps special safety regiment, with which, as deepening of the drifter is fixing the conductive cable to feed the rope special jimkami, otherwise he might be pinched or cut. Manually over-drilled pilot hole in the roof is fixed rocker block, over which is thrown a rope from the winch to the drifter. The winch is fixed to the soil anchors and expanding struts between the roof. Housing drifter raskrasavitsa in the development from turning with stretch marks, which complicates the preparation of the operation and the operation for releasing the drifter over well. Device to the rather narrowly functions - as a drifter, and uses the Executive bodies of the limited diameter of the penetration. In the case of using it as a drill unit for the extraction of ore treatment wells, extraction, it is, as before, must use a lot of manual labor, i.e. not enough mechanized and maneuverable in the work, as well as inefficient. The winch is connected to the drifter Gusenkov only a rope, which complicates the operation of the cable during their interaction in the process of drilling.

Object of the invention is the expansion of the functional and structural features of the drifter Gusenkov type PHS-1 in the direction of use for the treatment of the extraction chamber when the development system underground powerful and steeply dipping deposits of potash are the full height of the floor in a single run of the drifter.

The technical result of the invention is achieved by the fact that, as in the known device for underground development of powerful and steeply dipping deposits of potash ores, including the drifter Gusenkov type PHS-1, consisting of a body napravlyayus-spacer device with rollers on the rack, the two drive motors, planetary gearbox, external and internal Executive bodies rotating in opposite directions relative to each other and representing radiation crown with removable rays of the, which reinforced pads with a set of cutting elements; directing a hollow lamp, cable winch mounted on the frame; a rocker block, through which the winch is connected to the drifter esenkov the rope according to the invention, the drifter Gusenkov provided with a coupling made in the form of a combined swivel and collector and placed in the guiding device is made in the form of ribs on the inner surface of which is made of longitudinal grooves for accommodating racks with rollers napravlyayus-spacer device of the drifter, and fixed in the guiding device a locking device; the outer side of the guide vane installed at the bottom of the support jacks, and above - on an axis fixed rocker blocks for rope and cable; winch made double-drum - cable-cable, and placed on the frame of the tracked undercarriage double-drive part, the frame is supplied at the bottom of the front support jacks, and the top power arm pivotally connected with the guiding device, controlled from the cab; separate from the driver's cab placed remote control panel; power manipulator includes a boom hydraulic cylinder lifting - lowering guide vanes, hydraulic rotation of the boom about its axis by the angle α, the hydraulic cylinder, which Khujand which provides rotation of the guide vanes relative to the longitudinal axis of the boom angle β.

Matching features of the proposed device and the prototype: the use of drilling machines-drifter Gusenkov type PHS-1; the presence of a cable winch mounted on the frame; rocker pulley; the drifter Gusenkov contains: body napravlyayus-spacer devices at the ends of the racks which are fixed castors, two of the drive motor, planetary reducer, external and internal Executive bodies rotating in opposite directions relative to each other, representing a radial crown with removable beams, the ends of which are fortified pads with cutting elements, the guide hollow lantern.

Distinguishing features of the claimed device from the prototype: for the treatment of seizures potash use the drifter Gusenkov placed in it towed device for rope and cable in the form of a combined swivel with the current collector; double-drum winch; double rocker system to move the rope and cable; fixed blocks on the axis on guide apparatus; a guide device is made in the form of a shell with longitudinal grooves on the inner surface of the housing with a locking device for the drifter esenkov and hydraulic jacks, mounted under the guiding device; a power manipulator, turning angle of 30°, in different planes is moving up down the guide device during installation of the drifter Gusenkov over the pilot hole; the management device from the cab automatically using a remote control unit; duty cycle applications running crawler part with Autonomous movement of the left and right caterpillars on a frame which is placed in the transport position, the components of device nodes, chassis, front is equipped with a hydraulic Jack. Executive bodies of the drifter made with a diameter that provides for a single run of high-performance technological process of production of potash ore.

Comparative analysis of the claimed device with the prototype showed that the proposed is significantly different from the prototype - the presence of nodes and their relationships among themselves, a new feature known drifter esenkov and interrelation of the elements together at the nodes.

Unlike the prototype, in the inventive device, the winch is made of double-drum, i.e., supplemented cable drum. Moreover, their synchronized, which ensures continuous submission process of the drifter in the well without many gemkow cable, as before; and accordingly, simplification of the connection with the drifter. Complements the effect of the presence of the drifter trailer device for rope and cable in the form of a swivel, combined with a current collector, which ensures that, in case the e problem with the cable, timed shutdown of the system. Unlike the prototype winch placed on tracked chassis that allows you to: significantly simplify the whole supply system from top to bottom of the drifter Gusenkov to pre-made bottom - up pilot hole; to maneuver quickly, easily, from one well to another. Tracked undercarriage is made, in addition, double-drive, and, therefore, each part can maneuver on an individual task according to the passport.

Unlike the prototype manual labor when mounted rocker blocks (for rope and cable separately) no. They are installed and fixed on the axis on the guide device, and not in the roof ventilation drift, which simplifies the process of preparing the device for operation, eliminating injuries of workers, because they are absent in this zone.

In the inventive device, unlike the prototype, the drifter Gusenkov used for drilling water treatment wells, where the ultimate goal is the extraction chamber through a top - down, to give the ground (not blocks) ore due to the force of gravity when drilling on the drifter and ore. The drifter Gusenkov has only one-rope winch, move the cable to the drifter is not synchronized and complicated. Therefore, the drifter Gusenkov, issue Lenogo with the trailer device, employees at the same time and for rope and cable with Executive bodies with removable pads and cutting elements on them, you can perform the treatment wells, and not only passages for transporting people or equipment. The guide device in the form of a shell with grooves for movement of the racks with rollers napravlyayus-spacer device allows you to use the drifter with more than previously, extensive functional and structural features.

Unlike the prototype, the claimed device, as its integral part - the drifter Gusenkov has a significantly higher level of mechanization by combining relations guide vanes with a drifter Gusenkov in it and with the power manipulator that manipulates the position of the guide vanes and, accordingly, the drifter Gusenkov, promptly and accurately summing with tracked undercarriage guide apparatus for pilot hole, making turns at an angle (0-30°) in different planes relative to the axis of the boom. When the hydraulic jacks guarantee the stability of the system and the chassis and the drilling apparatus in General, and drilling the outer and inner Executive bodies in the stable regime, cut and beat the ore to the treatment well, to get the ore in the form of guaranteed crushed mother of the La, smooth going down under its own weight into the transport passage through the cavity in the guiding lantern, used the drifter Gusenkov.

Therefore, the claimed device has a technical solution, has a "novelty" and has significant differences from the prototype and other known devices of the same purposes (Kushnir Y., Systems development and systems of self-propelled machines in underground mining.

In both cases, external and internal Executive bodies are made in the form of radiation crowns with removable beams; directing the hollow yoke (34).

The device operates as follows.

First up from the bottom of the sublevel transport passage (35) using a self-propelled (Fig.6) drilling machine (36), given a passport drilling Buryats specified diameter pilot hole (37A), the full height of the floor with the lower sublevel transport passage (35) on the upper ventilation sublevel drift (38). Drilling fines generated in the drilling process, flows down under gravity directly or using mobile cranes (39A) on the conveyor (not shown). Then from top to bottom are practicing the basic array of potash ore in the chamber (40A) with ventilation sublevel drift (38) of the inventive device is the your (POS.1-34). For this pre-assemble the device (Fig.1-5): placed on the frame (2) crawler undercarriage (1) component parts, i.e., the guide apparatus with drifter Gusenkov in it (14-34), cab (7), power manipulator (9-12), double-drum (cable-cable) winch (3-6) to the actuators (not shown). Management is carried out from the cab (7) remotely, using a remote control unit (8). The device arrives at the pilot hole (b) (Fig.6), so that the guide yoke (34) of the drifter esenkov (22-34) was approximately over the mouth of the pilot hole. Tracked running gear are made with separate drives (1A and 1B) (Fig.1, 2), allowing Autonomous crawlers easy to maneuver, effectively, and in accordance with the passport drilling. When this power manipulator (9-12) (Fig.4) pushes the guide device (14) and, accordingly, the drifter esenkov (22-34) it pre-locked locking device (21) in the case of guide vanes (14) (Fig.2). This napravlyayus-spacer device is fixed in the longitudinal grooves (15) of the guide vane of the claimed device due to the presence in the body (25) durable (26) with rollers (27) at their ends, with the possibility of reciprocating movement along the slots.

With the help of rope and cable (4, 6) drums (3, 5) winches, thrown over peraki the blocks (16, 17) mounted on the axis (18) above in the case of guide vanes (14), and enshrined in the towed device (22) of the drifter esenkov (Fig.5), after turning on the cable drum winch, the drifter is exposed above the well (Fig.6) more precisely remotely operated remote control unit (8), power manipulator with position guide vanes above the well; move the guide apparatus (14) up-down - due to the connection of the hydraulic cylinder (10) with the boom; a hydraulic actuator (11) of rotation of the boom (9) to rotate the boom about its axis by the angle (α), respectively, and guide vanes at the same angle, and the hydraulic cylinder (12) connecting the boom with guide vanes, provides rotation of the guide vane above the pilot hole relative to the longitudinal axis of the boom angle (β) (Fig.4).

Move the rope and cable synchronized automatically. Further, in the working position are supporting the hydraulic Jack (13) caterpillar undercarriage and hydraulic jacks (20) of the guide vane device. Include the cable drum (5) winch, and the drifter rope (6) is lifted by longitudinal grooves (15) of the guide vane is up for removal of the drifter with the locking device (21). Then the drifter Gusenkov descends down the longitudinal grooves (15) and wound hollow guiding light (34) PI is now well (b) using the winch, having the rope and cable spanning the rocker blocks (16, 17) placed on the body of the guide vane (14). Then include motors (23, 24) and at low speed the drifter makes drilling the pilot hole, and then drilling with the formation of the treatment wells (40A), the diameter of which is determined by the outer diameter of the Executive body (29), (≈2.0 to 5.0 m).

Then, the casing (25) napravlyayus-spacer device, freed from connection with the guide vanes, the rack (26) with rollers (27) are moved along the slots (15) down, cut into the borehole wall and, thereby, the drifter to rotate around its own axis when the reactive moments of cutting crowns Executive bodies. Submission of drifter Gusenkov on the face is carried out under its own weight (5-6 tons and more), and the feed speed is adjustable with a remote control unit.

Repulsed potash ore in cleaning the well under its own weight goes (Fig.6) through a through hole in the guiding lantern down the pilot hole (b) in sublevel transport passage (35) and loaded on a vehicle (b). The process of cleaning drilling wells ends when the drifter zagubica in the array to full height floor to form a chamber (40B) and the abandonment of the pillar (41) floor (N).

After EXT is of the pilot hole prior to cleaning the drifter esenkov (he is in a new quality brown-bechna machine for drilling of treatment wells and for ore mining) maneuvering speed is given up on sublevel ventilation passage (38), got into a guide vane longitudinal grooves (15) therein and is fixed in the device a locking device (21). However with the speed of the drifter - cleaning machine synchronously is wrap the power cable (4) on the cable drum (3) and rope (6) on the cable drum (5) cable-cable winches. Upon completion of these operations the device is in transport position and moved to the next pilot hole (37V).

Depending on the physico-mechanical properties of the working layers of ore, the extraction can be carried out, for example, the isolated treatment of vertical chambers round shape, arranged in a checkerboard pattern or, for example, a continuous recess, etc.

To ensure high performance production of the inventive device in the camera on sublevel ventilation drift (38) can be used simultaneously several such devices. Ahead of the borehole is formed from the bottom up.

The inventive device in comparison with the prototype has the advantages of:

The device uses a known drifter Gusenkov for a new purpose - ore production by mining water treatment, wells, extending its functional and structural features;

the device allows to increase the level of mechanization about what it is possible to work in underground development of powerful and steeply dipping deposits of minerals;
