The invention relates to the mining industry and can be used for excavation of formation of minerals on hypsometry layer, including in difficult mining and geological conditions.

Known extraction machine for the formation of minerals that implements the method of extraction of minerals, including supporting mechanized mobile support is associated with a protective shield with the hydraulic jacks. The hydraulic jacks protective shield and supporting mechanized movable support is connected by hydraulic cylinders. Supporting mechanized mobile support and the protective shield consists of separate sections that are installed along the front of the extraction of minerals and rigidly interconnected automatic locks. Supporting mechanized mobile support is movably connected with a protective shield which can be moved relative to the lining in the frontal direction, together with their hydraulic jacks. The Executive body consists of auger sections related lanterns, rigidly interconnected automatic locks. The lights interact with the protective shield, roof and soil production through its lateral sliding supports. The cylinders are repelled from rasperry between the roof and the soil elaborate props. Doers the body in the process can make reciprocating and rotational movement relative to the protective shield from the actuator, placed in the excavation roadway [1]. The disadvantage of the mining machine is very energy intensive destruction of the surface of the shaft and the inability to control the position of the mining machine relative to the reservoir. Most energy fracture formation is a consequence of the fact that the Executive authority, in the form of a screw sections, together with its related supporting mechanized mobile support is placed along the front of the face and can destroy the bottom surface only across the front of the notch. In addition, the Executive body performs reciprocating motion without the protective shield, which creates an additional resistance to the promotion of destructible cutters of the rock mass along the front of the excavation of the reservoir in the direction of its discharge. The lack of controls provisions of sections supporting mechanized movable supports relative to the reservoir leads to inability to retain all rod sections in the plane of complex hypsometry layer. This leads to dilution of the mineral.

The closest technical solution, selected as a prototype, is the extraction machine for the formation of minerals, including sections supporting mobile mechanized roof supports having longitudinal guides. Section protective shield installed on about the Aulnay guides. With them kinematically connected section of the Executive authority with the drive and installed along the front of the excavation of the reservoir. Partition-aware mobile mechanized roof supports installed along the front of the excavation of the reservoir are connected to each other through the branches of the couplers, the tension of which is adjustable tensioning and adjusting devices mounted on the extreme sections. Becoming sections supporting mobile mechanized roof supports, by changing the tension of the branches of the couplers can change the curvature of the entire rod sections and pass it through the longitudinal guides of the rod protective shield followed by the Executive body, adapting it to hypsometry layer. However, the Executive authority, together with the protective shield can be moved along the longitudinal guide [2]. A disadvantage of the known mining machine is very energy intensive destruction of the surface of the shaft and the inability to control the position of the sections of the Executive body relative to the reservoir. The greater intensity of the fracture surface of the face due to the fact that sections of the Executive body destroy the bottom surface only along the lines of cutting, directed across the front of the recess, i.e. across the strata of the rock mass. The mining machine has no means of controlling the position it relatively square is one hundred and minerals when driving on his hypsometry. The result is a dilution of extracted mineral. The above-mentioned disadvantages do not give the opportunity to increase productivity by reducing the energy intensity of the process of destruction of the surface of the face and reduce the dilution of minerals in difficult mining and geological conditions of occurrence of the layer.

The objective of the invention is to increase productivity of the mining machine and reducing the dilution of the extracted rock mass. The problem is solved by reducing the energy intensity of the destruction layer of the mineral and control the position of the mining machine relative to hypsometry layer.

This object is achieved in that the extraction machine for the formation of minerals, including sections supporting mechanized mobile lining with longitudinal guides have sections of the protective shield, kinematically connected with the sections of the Executive body with a drive along the front of the excavation of the reservoir, according to the invention provided with brackets cutters for the destruction of the bottom surface along the cutting lines directed along the front of the excavation of the reservoir, with the step of providing the abandonment of Zelikow between them, linking sections of the Executive body with the drive and ill is to be installed on the sections of the protective shield with the drive it is moved along the longitudinal guide sections supporting mobile mechanized roof supports. The mining machine is equipped with traps for sampling the rock mass from destructible cutters downhole from the surface along the lines of cutting, designed along the front notch of the reservoir. Brackets cutters are equipped with holders for the implementation of the cutters in the bottom surface during movement of the sections of the protective shield along the longitudinal rails along the front of the excavation of the reservoir towards the unloading of the rock mass of the mining machine.

Significant differences of the proposed solutions from the prototype is that the mining machine for formation of minerals supplied with brackets cutters for the destruction of the bottom surface along the cutting lines directed along the front of the excavation of the reservoir, with the step of providing the abandonment of Zelikow between them. Brackets cutters connecting section of the Executive body to the actuator. Brackets cutters rigidly mounted on the sections of the protective shield with the drive it is moved along the longitudinal guide sections supporting mechanized mobile lining. The mining machine is equipped with traps for sampling the rock mass from destructible cutters downhole from the surface along the lines of cutting, designed along the front notch of the reservoir. Brackets cutters are equipped with holders for the implementation of the cutters in the bottom surface during movement of the sections of the protective shield on prod is determined as being the guide rails along the front of the excavation of the reservoir towards the unloading of the rock mass of the mining machine.

Supply mining machine arms with cutters for the destruction of the bottom surface along the cutting lines directed along the front of the excavation of the reservoir, with the step of providing the abandonment of Zelikow between them, you can go from clear cutting to cutting education Ironman slots of the brackets with the cutters for the destruction of the bottom surface along the cutting lines directed along the front of the excavation formation, followed by the breaking off of small mislevy Zelikow Executive body with actuator [3, p.81]. This process has a lower energy intensity of destruction than the dilution of the face of continuous cutting. Low energy consumption of the process is ensured by the fact that the destruction of the face is partially from the surface of the face along the lines of cutting, designed along the front notch of the reservoir, i.e naplastovany. [3, p.56]. Linking arms with cutters sections of the Executive body with the actuator between a allows you to place in a single device fracture surface of the bottom line of cut, directed along the front of the excavation of the reservoir by means of arms with cutters and across the front of the excavation of the reservoir with the help of the Executive body to the actuator. Hard to install the brackets with the cutters on the sections of the protective shield with his drive is necessary for the transmission to them of the efforts directed along the longitudinal napravlyayus is from actuator displacement. Supply of mining machines are traps for sampling the rock mass from destructible cutters downhole from the surface along the lines of cutting, designed along the front of the hole, allows you to control the position of the rod sections of the Executive body with the drive and support mechanized movable supports relative to hypsometry formation of minerals in the operations control movement of the machine while removing the protective shield with the Executive body and arms with cutters on the excavation of the roadway. Supply arms with cutters cutter holders for the implementation of the cutters in the bottom surface during movement of the sections of the protective shield along the longitudinal rails along the front of the excavation of the reservoir towards the unloading of the rock mass of the mining machine reduces the resistance of the rock mass promotion for her discharge. This is due to the fact that the transportation of rock mass coincides with the direction of the destruction of bottom brackets with cutters.

All of the above symptoms together, in comparison with the known technical solutions that increase the productivity of the mining machine and reduce the dilution of the extracted rock mass that allows to use it when pulling stronger minerals with complex hypsometric layer. The design is emochnoy machine remains quite simple and easy to manufacture. Thus, the inventive extraction machine for formation of minerals on the combination of these characteristics, corresponds to the criterion "novelty".

The solution is a new technology. It is possible to apply the extraction machine in more complex geological conditions of mining solid minerals without the need of a permanent human presence in hazardous areas of production, which significantly exceeds the increment of these qualities previous improvements and suggests that the distinctive features are significant.

The technical essence of the invention is illustrated by drawings, where:

- figure 1 - General view of the excavation machine, located in the plane of the layer mineral;

- figure 2 is a longitudinal section a-a figure 1 - the passage of the mining machine on hypsometry formation of minerals;

- figure 3 is a section along B-B in figure 1;

- figure 4 - node I on Fig movement arms with cutters in the direction of the unloading of the rock mass of the mining machine;

- figure 5 - node I in figure 1 - movement arms with cuts in the opposite direction.

Extraction machine for the formation of minerals (figure 1, 2, 3) includes a section supporting mobile mechanized roof supports 1, installed in the formulation 2. On the lateral surfaces of the sections kr is PI 1 are longitudinal guides 3, located along the front of the excavation of the reservoir 4. On the longitudinal guides 3 adjustably mounted interconnected sections of the protective shield 5 actuator moving it 6. On the sections of the protective shield 5 is rigidly mounted brackets with the cutters 7, linking sections of the Executive body 8 is rotated in the direction (ωactuator 9. Brackets cutters 7 are destroying the bottom 10 from the surface of the cutting lines 11, designed along the front notch of the reservoir 4, step (X)providing for the abandonment of Zelikow 12 between them. On the brackets cutters set traps 13 (figure 4, 5) for sampling the rock mass 14 from destroying the brackets with the teeth 7 of the bottom 10 from the surface of the cutting lines 11, designed along the front notch of the reservoir 4. Brackets cutters 7 is equipped with holders 15 for introducing them into the surface of the bottom 10 during movement of the sections of the protective shield 5 actuator moving 6 along the longitudinal guides 3 sections supporting mechanized mobile lining along the front of the excavation of the reservoir 4 toward the unloading of the rock mass of the mining machine. Brackets cuts 7, together with the Executive body 8 and the protective shield 5, make a reciprocating motion in the direction ofandwithin its working the plots ().

Extraction machine operates as follows. After installation sections supporting mobile mechanized roof supports 1 in generation 2, in their longitudinal rails 3 installed along the front of the excavation of the reservoir 4, the slide section of the protective shield 5 actuator moving 6. Together with the protective shield 5 slide and rigidly mounted thereon brackets with blades 7, which connect between a section of the Executive body 8 with the actuator 9. When the movement supporting mechanized mobile roof support 1 on the bottom 10 of the brackets with the cutters 7 do together with the protective shield 5 reciprocating motion in the direction ofandfrom the actuator move 6 and destroy the bottom 10 from the surface of the cutting lines 11, designed along the front notch of the reservoir 4 with step (X)providing for the abandonment of Zelikow 12 between them. The Executive body 8 rotates in a direction (ω) from the actuator 9 across the front of the excavation of the reservoir 4, destroys zalicki 12 left brackets with blades 7. In the destruction of the bottom 10 brackets with the cutters 7 send the rock mass in the trap 13. During the reciprocating movements of the arms with cutters 7 in the direction ofandwithin working areas (U) on especially continuity of the cutting lines 11. Thus each successive sample of the rock mass 14 is pushed out of the trap 13 previous. While removing sections of the protective shield 5 from generation 2 to study the composition of the samples of the rock mass 14 in the trap 13 and the results of the study will govern the direction of movement of the mining machine. When the movement of the protective shield 5 in the direction ofthe holders 15 under the action of forces of resistance of the rock mass are installed in working position and embedded in the surface of the face 10 (figure 4). This destruction of the face 10 is in the direction coinciding with the direction of movement of the rock mass, i.e. in the direction of the unloading of the rock mass of the mining machine. During the reverse movementprotective shield 5, the holders 15 are installed under the action of forces of resistance of the rock mass in the off position (figure 5), without interfering with the Executive body 8 to transport the rock mass in the direction of its discharge from the mining machine.

The proposed extraction machine for the formation of minerals, in comparison with the prototype, allows the extraction of more solid minerals with higher performance or lower power consumption. The use of traps allows us to predict the trajectory of the mining machine, which is necessary for the implementation of the reg is irowiki controls if you need to change the trajectory of its movement. This reduces the dilution of the mineral. Use holders can reduce the resistance of the rock mass transportation it towards the discharge of the excavation machine.

The above allows you to apply extraction machine for unmanned technologies production of strong mineral than the host rock and retrieving a particular economic effect on mountain mining and enriching enterprises.
