The invention relates to the mining industry, in particular for constructive bodies of mining machines, namely, tunneling, excavation and harvesters, and can be used on treatment tunnel complexes in the extraction of minerals, such as coal, oil shale, rock salt and limestone, both underground and open pit methods.

Known Executive body of the mining machine, Deplete minerals, transforming it into a fine fraction auger equipped with radial blades /1/.

The disadvantage of this Executive body is getting pereselenskogo coal with a large output of rubble and dust, as well as the high complexity of its destruction.

The closest analogue to the invention is the Executive body of the mining machine, including mounted for rotation body in the form of a disk, on which the periphery of the holders are portaretratos tools /2/.

The disadvantage of this Executive body is also low grade of extracted mineral and the high complexity of the destruction of the array.

The objective of the invention is to increase the efficiency of extraction of minerals, increasing its grade and safety Executive body and all mining machines.

This task is achieved by the fact that ispolniteltnom the body of the mining machine, includes mounted for rotation body in the form of a disk, on which the periphery of the holders are Portorosa tools on the working surface of the disk on a circle with radius equal to ½ of the radius of the disk, still placed the glasses, which are installed with the possibility of a pulsating movement along its axis pointed cone conical shape, while at the same radius in the disk is made an odd number, at least one through hole in the form of a truncated cone in cross section of the disk, tapering from the disk surface, on which the cone, back to his side.

Figure 1 shows the diagram of the destruction of the array mineral mining machine;

Figure 2 shows a General view of the Executive body of the mining machine;

Figure 3 is a section along a-a in figure 2;

Figure 4 is a cross section of the valve body of the mining machine.

The Executive body of the mining machine includes mounted rotatably on the shaft 1 case in the form of a disk 2, which is on the periphery of the holders 3 are Portorosa tools 4, wherein the working surface of the disk on a circle with radius equal to ½ of the radius of the disk, still placed the glasses 5, which is installed with the possibility of a pulsating movement along its axis 6 seastrand the e cone 7 of conical shape, oriented to the slaughter.

On the back of the disc cover 2 installed 8 located on the same radius as the roller cutter on the disc, cantilever racks 9, the end portion of each of which is a flange 10 and the cone is made on its longitudinal axis with an inner bore 11 of stepped form.

The extension of the milling cutter is limited installed on a rack 9 washer 12, resting in the notch of the inner bore of the milling cutter. Reverse cone is limited by the flange 10 of the cantilever rack 9 of the cover disk. Pulsating movement of the milling cutter is provided, for example, a generator of pulse pressure, communicates with the cavity of the Cup and cone, or by means of mechanical transmission by means of eccentrics.

The Executive body of the mining machine operates as follows.

The destruction of the array of minerals is super narrow strips by creating advanced slit and the subsequent separation cut hinged packs Executive body of the mining machine.

When simultaneous translational movement and rotation around the shaft 1 of the Executive body of the mining machine in the interaction with the destructible rock come first Portorosa tools 3, resulting in large initial destruction of the breed, and then cone.

The location of the cones 7 disk RA is iusu, equal to ½ the radius of the disc, provides additional destruction of the breed, and in the area with the greatest concentration on the working body after isolation from the working surfaces portaretratos tools that allows you to get the specified grade of the extracted mineral.

However, when the destruction of the breed along with grade material particles are formed of small particles, which reduce the efficiency of operation of the working body and all mining machines, as degrade the environment of the work area, and in some cases possess the ability of self-ignition. With this in mind, in this Executive body is stipulated the removal of small particles from the work area, which at the same radius, which are cone made an odd number, at least one through hole 13 in the form of a truncated cone in cross section of the disk, tapering from the disk surface, on which the cone to the rear side 14 of the disk.

Performing an odd number of holes in the disk provides runout, which increases the efficiency of rock breaking rock cutting tools and milling cutters, and also facilitates the efficient removal of small particles from the working area of the mining machine.

The destruction efficiency is increased due to the fact that cone commit pulsating movement is giving. At the meeting, for example, with inclusions of high hardness in the rock, the roller cutter, naratiwas on it, has the ability to retract into the Cup 5 to contact with the shoulder 10 of the cantilever rack cover.

The signal on the nomination of the roller cutter gets in contact overhanging the top edge of the hub 15.

To protect against wear from the location of the cutter disk is closed by a cover 16.

Thus, this design is the Executive body of the mining machine can improve the efficiency of extraction of minerals, to improve his grades and to ensure the safety of work of the Executive body and all mining machines.

Rock cutting method // 2266408

FIELD: mining industry, particularly for underground crystalline raw material production.

SUBSTANCE: method involves forming additional free surface by cutting advance entry way; drilling a row of bore-holes in block; disturbing rock in all bore-holes of the block and following moving thereof to additional free surface in layers. The bore-holes are drilled for depth equal or exceeding one fourth of advance entry way depth and the bore-holes are filled with pliant substance. Disturbing cracks are formed by displacing the pliant substance from the bore-holes. The cracks extend in a given direction in plane perpendicular to mine roof and sole planes.

EFFECT: possibility of natural crystal size conservation.
