(54) DEVICE FOR DEVELOPMENT OF RESIDENTIAL DEPOSITS OF MINERAL RESOURCES

one

The invention relates to the mining industry and is intended for the selective mining of gangue deposits, varying in direction.

A machine dg d1 of excavation works is known, carrying out the extraction of strong minerals and containing a working body in the form of a disk with segments of chains fixed on it with weights at the ends I.

The disadvantage of such a machine is the low elasticity of the segments of the chains, which are prone to start up at the moment of starting the machine. In addition, before starting the hem it is necessary to perform poverty or move the self-propelled shelves with the machine to the initial position at the beginning or end of production, which requires additional labor costs.

The closest to the invention in technical essence and the achieved effect is a device for mining mineral deposits, including a self-propelled shelf moving along a monorail with a 20 excavation machine installed on it with a working body and traction elements for moving along a monorail | 2).

However, in curved sections, at the junction points of the monorail sections, the arrangement of the traction elements is disturbed, which has a detrimental effect on the operation of the movement mechanism of the self-propelled regiment. The use of blasting blasting destroys the valuable mineral and mixes it with the rock.

The purpose of the invention is to ensure the efficiency of development in field distortions.

This goal is achieved by the fact that the device, which includes a self-propelled shelf moving on a monorail with an excavation machine mounted on it with a working body and traction elements for moving on a monorail, is equipped with hinged clips with a monorail, in which the traction elements are located, and made in the form of flexible threads with crowns and body with a hollow spindle placed in it to the motor, while the flexible threads are connected to the spindle by means of a spring.

FIG. 1 shows a device in the steeply sloping lava of a mineral deposit; in fig. 2 - carriage with a car on the monorail section; in fig. 3 - the same in terms of; in fig. 4 - the working body of the machine; in fig. 5 - holder with traction elements; in fig. 6 - engagement of the spiral groove of the lifting member with the traction elements; in fig. 7 - portable mining complex. The device comprises a moving along the face of the monorail 1, mounted from the section. The sections have spacer and monorail-moving devices 2 (hydraulic pushers). Along the guide channels of the 3 sections, the self-propelled shelves 4 are moved with a lifting member and a excavating machine with a working member. The working body of the excavation machine includes a flexible thread 5 reinforced with a refractory crown 6 or diamond cut, which is threaded at one end into the hollow spindle 7 through the radial holes of its extreme part and attached to the stretching spring 8 inside it. The full spindle is mounted in the inner rings of the bearings 9 the housing 10, which is fixed by a nut P and the strut 12 of the base 13. The rotary type air motor 14 is integrated in the housing 10. The lifting member 15 is made in the form of a conical disk with a spiral groove, which is mounted on Khodnev shaft gear 16 to the motor 17. The elevating body is in engagement with m govymi elements 18 are pairwise mounted in holder 19 which is pivotally attached to the guide 20 of the monorail. The monorail sections are interconnected by bolts 21 in a pin-to-sleeve manner 22. The principle of operation of the mining complex is as follows. The rotational movement of the engine 17 is transmitted through the gearbox 16 to the lifting body 15, which, when interacting with a pair of traction elements 18, converts the rotational movement into a translational movement of the self-propelled shelf with the excavating machine moving along sections of the monorail 1. The guide channels of the channel 3 reliably keep the shelves from tipping . The most difficult for passage section of the path is the place of the section joining, where during installation in a curvilinear development a significant error in the arrangement of the clips 19 can be made. Articulated on the rail 20 of the clutch 19 with a pair of traction elements 18 when interacting with the helical groove of the lifting organ 15 balance weight compensate for the error of placement, ensuring smooth engagement with the next rollers to the main even distribution of effort on the turns of the spiral groove. Thus, the interaction of the lifting unit with the traction elements, assembled in clips, ensures the smooth movement of the self-propelled regiment in curved mine workings. The expansion of the monorail and the removal of the sections are made from the cab of the self-propelled regiment. Fixing and movement of the monorail after the bottom is carried out using spacers and shifting devices 2. The ore body is extracted by rotating flexible thread 5, which is set in motion by rotary air motor Y. With increasing number of revolutions of the hollow spindle 7, flexible thread 5, in the form of a steel cable, fitted cutting crown 6, under the action of centrifugal forces rushes through the radial holes, stretching the spring 8 and embedded in the bottom. The depth of the cut is governed by the speed of rotation of the spindle. After the bending thread completes the notch, the lifting member is activated, which, smoothly moving the self-propelled shelves with the machine, makes the hemming of the bottom. The housing 10 rotates on the base 13 around the post 12 and is fixed in the desired position by the nut 11, ensuring the direction of the desired cut. Several self-propelled regiments can be used on the monorail, producing vertical and horizontal cut-outs, and slots separated from the bottom of the minerals. The device makes it possible to mine for a more progressive technological scheme using the lavas method, selective separation from the array of valuable mineral, followed by delivery to the haulage roadway. The invention The device for the development of mineral deposits of the core, including self-propelled mixing shelves with a monorail with a working machine installed on it and working elements and mono-rail components, characterized in that, in order to ensure the efficiency of development in field distortions , it is equipped with hinge-connected monorail holders in which the traction elements are located, and the working body is made in the form of flexible threads with crowns and housings with therein is a hollow spindle and a motor, while the flexible threads are connected to the spindle by means of a spring.
