1. Known excavation front unit (avts USSR SU # 1493793 A1, publ. 02.03.1987), which includes a database associated with the hydraulic Jack of movement with shields containing the base, connected by hydraulic jacks with overlapping, the handle of the Executive body, face the ends of which are fixed cutting heads, and they dammed the ends of the hydraulic Jack swing and lift, with each shield section provided with a rack, which is rigidly fixed to the base with the dam side with respect to the hydraulic cylinder of lifting, and a platform hinged at one end to the rack, and the other end connected with the hydraulic cylinder of lifting. Each handle is made with two shoulders a yoke on the dam end and telescopic along its axis. While the middle portion of the rocker arm mounted on the platform by the vertical axis, and the ends of the rocker arm associated with the platform hydraulic cylinder swing.

A disadvantage of the known extraction unit is its low reliability, because telescopically handles of the Executive body and change their departure during the extraction of coal is slimming and the cutting forces. This is because of the efforts developed by the hydraulic Jack swing, remain constant, and the shoulder of handles increases. If excavation of coal on a given chip thickness is a few tricks, this entails increasing the intensity of the process of coal extraction. This excavation unit cannot seize coal taking into account stratification, which could significantly reduce energy blasting. Also if you get a chisel on a solid inclusion in the corner is often a jammed due to the lack of cutting forces for the destruction of incorporation, and the unit is unable to continue working. This unit aims to work on the extraction of minerals and is not suitable for niches in the complex-mechanized Stopes.

2. Known powered system in the front of mining coal seams (Zagrivny E.A., Vinnikov H., Smirnov, YU. and other Mechanized system for the front of mining coal seams // journal "Coal". - 1998. No. 7. - S-23.), including transport device (conveyor) with a cutting chain with downhole his hand, sections of powered roof supports, and related hydraulic cylinder movement with the transport device and containing the base, the hydraulic jacks and overlap, and extraction devices, each of which is made in the form of the multi-link arm mechanism,comprising two handles, at the downhole end of which is fixed cutting heads, and they dammed the ends through the l-shaped rocker arm is connected with the hydraulic Jack swing, platform, within which there is a hydraulic Jack swing, and manipulator containing a rigid lever, made in the form of a planar element, gidrotartrat filing and gidrotartrat lifting. However gidrotartrat lifting and gidrotartrat supply oriented relative to the rigid arm with its face side. And some of the ends of the rigid arm and hydraulic cylinder lifting associated with the platform, and the hydraulic cylinder feed stiff - arm. The other end of the rigid arm mounted on the transverse lever and relative to the base along its width, and the other ends of the hydraulic jacks raise and feed also mounted on this lever, the dammed end of which is through hydropattern rests on the base of the shield. Excavation device installed in increments of two steps of the installation of shields.

The disadvantage of mechanical complex is the lack of opportunity to seize the coal taking into account stratification, which could significantly reduce energy blasting and reduce the required cutting forces. Also powered system cannot destroy the solids found in coal, for the destruction of which require significant is violence. This machine is intended for the extraction of minerals and is not suitable for niches in the complex-mechanized Stopes.

3. Known front cleaning unit (RU patent 2224111 C1, publ. 13.06.2002)adopted for the prototype, including a transport device with a cutting chain with downhole his hand, sections of powered roof supports, and related hydraulic cylinder movement with the transport device and containing the base, the hydraulic jacks and overlap, and extraction devices, each of which is made in the form of the multi-link arm mechanism, consisting of two handles on the downhole ends of which are fixed cutting heads, and they dammed the ends through the l-shaped rocker arm is connected with the hydraulic Jack swing, platform, within which there is a hydraulic Jack swing, and manipulator containing a rigid lever, made in the form of a planar element, gidrotartrat feed and gidrotartrat rise, located on the downhole side of the rigid arm, and some of the ends of the rigid arm and hydraulic cylinder lifting associated with the platform, and the hydraulic cylinder feed stiff - arm, the other ends of the rigid arm, hydraulic cylinder feed and hydraulic cylinder lifting each arm is mounted on the downhole side of the overlapping section of powered roof supports with orientation of estrago lever between the hydraulic cylinder feed and hydraulic jacks lift and across the width of the overlap, and gidrotartrat supply is located on the goaf side of the rigid arm, and extraction devices installed in unit increments, defined by the set expression.

The disadvantage front of the purification unit is the lack of opportunity to seize the coal taking into account stratification, which could significantly reduce energy blasting and reduce the required cutting forces. Also cleaning unit cannot destroy solids found in coal, for the destruction of which require significant effort. Front cleaning unit is not able to produce a niche for translation of the harvester to the next strip coal complex-mechanized Stopes.

The technical result of the invention is that the extraction module provides the ability to the breaking of coal with regard to the coal strata of the array and allows the breaking of coal large chip, which reduces the required cutting forces, reduces the specific energy consumption, increases productivity and eliminates pereselenie coal.

The technical result is achieved by the extraction module, which includes a shield containing the base, the hydraulic jacks, the overlap of which is fixed extraction device according to the invention includes in its status is in the extraction device, made in the form of a pointing device capable of positioning the Executive body, on the face side of which is fixed salavatli unit drummers and cylinder rotation block drummers, and on the dam side are the cylinders swing and rotation, mounted on the platform is configured to move along the overlap section of powered roof supports with hydraulic feed.

The essence of the device is illustrated by drawings, where: figure 1 - schematic diagram of the module, General view; figure 2 shows a diagram comprehensively mechanized stope (CMOS), equipped modules; figure 3 is a view of the niche front.

Extraction module includes a shield 1 (figure 1), which is associated with the main conveyor 2 by means of the shifting cylinder 3. Main conveyor downhole side can be equipped with a cutting chain or a wiper device 4. The visor 5 mechanized roof supports can be made retractable shearing type. In the mechanized roof supports, consisting of a base 6, floors 7 and the legs 8, set the rotary platform 9, which can be moved by means of hydraulic cylinder 10. The platform can rotate around the vertical axis. The platform is fixed arm 11, which is positioned with the help of open the cylinder 18. Part of the manipulator enters the cylinder of rotation 12, which is operated by the rotation of the manipulator along the axis of the feed cylinder 13 of the Executive body 14 of the module on the bottom. In the composition of the Executive body consists of salavatli 15, fixed in the head with links to the block drummers 16. The Executive body may bend due to the cylinder of rotation 17.

The work of excavation module comprising a complex-mechanized stope is as follows: the ends stope equipped with one or two excavation units (figure 2). The number of extraction modules 19 end sections depends on the number of niches that need to be prepared for the notches of the auger of the combine 20. The modules perform niche in the moment when Shearer extraction is not on the respective end section. Excavation modules are prepared niche for the size of the hub of the auger of the combine. This formulation does not require fastening. The design module allows these devices except for the blasting of the rock mass to perform the operation of loading the broken material on the main conveyor 21. When niches are ready, the modules are formed in such a way that does not create barriers to the movement of the Shearer of the main sections of powered roof supports 22 and serving the bottom of the staff. The notch cleaning comb is in front is advancing the conveyor along with the combine to the slaughter, while the hub of the auger of the combine is in the hole without resistance, the rest of the array to the size of the blades of the auger breaks end cutters, and destroyed minerals unload auger blades directly on the pipeline.

Performing niche (figure 3) excavation module is produced by blasting of rock mass salivates 15 (figure 1), which is embedded in the array when the extension of the hydraulic cylinders 10 and 13. Blasting of the rock mass is a series of consecutive chips with a given step. The positioning of scalinatella to mine is made by hydrocylinder 12, 17, 18 and the turntable 9. Block the hammers 16 allows, if necessary, to destroy the array by attacking array salivates.

Thus, the design of the excavation module provides obtaining the claimed technical result.

Extraction module including the shield containing the base, the hydraulic jacks, the overlap of which is fixed extraction device on the dam side of which are the swing cylinders, characterized in that the extraction device is designed as a manipulator unit drummers with salivates with downhole hand, are equipped with hydraulic rotation unit drummers and the cylinder of rotation of the arm pivotally connected to the head of InEU party platform, made with the possibility of movement along the overlap section of powered roof supports with hydraulic feed.

SUBSTANCE: combine includes bioenergetic complex which brings the bit into rotation. The above bit is located in lower part of cylindrical combine along the perimetre of which the reactors filled with water and with oil above water are located. When water freezes in reactors contacting with permanently frozen soil of the well, ice displaces the oil which, when entering hydraulic pressure members, brings the seals into action by pressing them against the well walls. Seals being the counter-weight of the bit lift the bit through pulley block system a little; at that, the well space under the bit is filled with hot steam formed in reactors as a result of activated heaters arranged in reactors, which leads to softening of kimberlite. At that, excess pressure in oil reservoirs is used in electric generators for electric energy generation, and cleaned and demineralised water from reactors is directed to bioenergetic complex for regeneration of solution feeding the plants. Combine is equipped with system of wet separators and diamond reservoir, which are serviced with microescalators, manipulators and video cameras, which allows, as the combine moves downwards at any horizon of the well, taking the decision on expediency of development of kimberlite massif.
