    The invention relates to the mining industry, in particular, to a method for carrying out a combined centrally mechanized excavation of predominantly solid mineral raw materials and a device for its implementation. A known method of hydromechanized coal mining, based on the destruction of coal by cutting nozzles without using a cutting plow tool, is also used when the nozzles are operated with large quantities and low water pressure, coal comes out in the form of sludge if the plane with a relatively low water pressure is generally capable of notching enough coal. Coal can be extracted in sufficient quantities by using a high water head in the nozzles, but this causes a regular high energy consumption to produce a high water head. The closest in technical essence and achievable effect is the method of a combined hydrographic extraction of predominantly mineral minerals consisting of a series of high-pressure liquid jet sequential destruction and mechanical destructive tools interacting with a liquid jet. A device for carrying out this method includes crushing heads in which nozzles with nozzles are installed in their bodies, while the crushing head is made in the form of a wedge C2. The disadvantage of this method and device is the inability to adapt to the hardness of the mineral so that the overall process provides the maximum amount of coal and minimal energy consumption. The aim of the invention is to increase the destruction efficiency and reduce energy costs. The goal is achieved in accordance with the method of combined hydromechanized excavation of predominantly solid mineral raw materials, including the sequential destruction of a mineral by a high pressure liquid jet and mechanical destructive tools interacting with a liquid jet, a liquid jet constantly pumping up and down in a vertical plane, the swing plane having at an acute angle relative to the bottom, and mechanical destructive tools at the same time fulfill the horizon cial oscillating movement and mounted on an adjustable distance for the liquid jet. A device for carrying out the method, including crushing heads installed on the plow, in the housings of which nozzles with nozzles are installed, while the crushing heads are made in the form of a wedge and are installed with the possibility of rotation, and the nozzles are equipped with rotatable pipes with nozzles at their ends, wherein the plow is provided with a drive coupled to the crushing heads through the forward movement elements of the heads in the horizontal direction and through the movement elements in the vertical direction. In addition, the nozzle tube is installed with the possibility of rotation of the woks of its axis and is connected with the rotation drive, while the nozzle is mounted on the tube at an angle. In addition, the angle between the nozzle and the axis of the nozzle tube is 90-180. The swivel tube is installed at its upper end with the possibility of turning on a support. Between the nozzle rotary tube and the actuator, there is provided a connecting element on the support having a connection for receiving a fluid pipeline, and a coupling element for connecting the rotating actuator coupling rod. A second coupling element is located on the rotation drive for the forward rotational movement of the coupling rod. The swivel tube and the slew drive are supported by means of supporting elements on a plate connected to the body of each shot head. The turning wedge of the crusher head located on both sides of the nozzle is equipped with a rotational drive device mounted around the casing of each crusher head around the crushing axis. In addition, the device has an intrinsically safe time relay for controlling the activation of the nozzle with the advance of the start of the split head. The invention is based on the task of creating a method of hydromechanically excavating a predominantly solid mineral and a device for carrying out the method by restructuring and improving the known basic elements. c- The hydraulic cutting tool interacts with the mechanized crushing tool so that the excavation process, consisting of cutting and crushing, is adapted to the hardness of the mineral so that the overall process gives the maximum amount of coal extracted and the minimum energy consumption. At the same time, this result should be achieved without additional difficulties of excavation, without additional processes in the further processing of the extracted material and without additional labor costs. According to the proposed method of combined hydromechanized excavation, the mineral in a solid state of aggregation is continuously cut by a mining machine with a water jet of maximum pressure; dissected from the state of aggregation with a crushing tool fixed in the mining machine, and sent to vehicles and sent from the bottom. To achieve this task, a new combination of parts of the excavation process is necessary, namely the temporary coordination of the processes of cutting and crushing . This is ensured by the fact that the continuous excavation is carried out in such a way that the cutting of the material is carried out with a controlled advance relative to the crushing. Part of the cutting process depends on the hardness of the material, so the excavation must be done in such a way that, during cutting, the pressure and amount of water are adjusted according to the hardness of the mineral. In order to match the method of excavation and material hardness, the material is cut by only one nozzle with a maximum liquid pressure or with a very hard nor fossil through several nozzles. Part of the crushing process also depends on the hardness of the material and additionally on the cohesive forces of the mineral aggregate. Therefore, the excavation should meet these conditions. According to the proposed method, the cutting of the cut mineral is performed by means of a wedge-type impacting or rotating tool with an adjustable force of impact and rotation. Part of the process of rolling back mined minerals is carried out in a known manner by conventional vehicles. The method of excavation according to the invention can be coordinated with the set production plan in that the mineral is excavated in only one direction. Due to the production of the excavation in both directions, it is possible to achieve the extraction of almost double the amount of minerals with relatively minor additional equipment. Coordination of the method of excavation with the power of the mineral. The excavation method for combined hydro-mechanized mining should also satisfy additional conditions, i.e., the safety and health requirements of the operating personnel and the subsequent processing of the mineral and application. The proposed excavation method prevents explosions in gas-fired faces by selecting the pressure and amount of water when cutting mineral resources and adjusting them so that the possibility of sparking is eliminated. The high-pressure jet of fluid effectively prevents the ignition of the gas released when the mineral is cut. A significant improvement in the working conditions of the personnel is achieved by the fact that the pressure and the amount of fluid in the high-pressure jet during cutting are adjusted so that during the cutting process the minimum possible amount of dust-like mineral is formed. Thus, the method of excavation contributes to the fight against dust, which is more effective than usual. Use it in a wetting method. Combined hydromechanized mining can have a significant impact on the important properties needed to enrich the mined mineral, namely graininess and water content. This is the advantage of the method; It is especially important for the extraction and further processing of mineral coal, since coal mines and coal dust are expensive to be processed into a sold lump product. The lumpiness of the mined product according to the invention is achieved by the fact that during cutting, the thickness of the seam mineral that is being adjusted is adjusted to the desired grain size of the product. To prevent the formation of large quantities of fine-grained slime-like product during cutting, the pressure and the amount of high-pressure fluid are adjusted so that the water content in the extracted product does not exceed the value allowed for subsequent enrichment. In order to carry out the method of excavation, a mining machine is required, according to the invention, on one or both end sides of the cutting and crushing head, in which a set of nozzles as a cutting tool for cutting and a crushing tool for crushing the mined product are placed. For the efficiency of the excavation method, it is important that the cutting process be ahead in time of the crushing process. To do this, turn on the force | Nok kit using an intrinsically safe relay (the time is adjusted ahead of the turn on the crushing tool. pipe nozzle, a supporting element for a rotary pipe, installed between the rotary pipe and its drive connecting element, installed on it from the side the rotary tube coupling element, connecting rod, connecting element on the drive side, driving the swing mechanism with the support and the fluid supply system.As a result of the reciprocating movement of the rotary tube along its axis, the nozzle splits the vertical gap in the This cutting jet, moving from top to bottom, is formed due to the fact that the axis of the nozzle mounted on the rotary tube has a relative inclination to the longitudinal axis of the rotary tube, the angle of inclination is from 90 to 180, NOSTA high pressure jet from the nozzle is largely dependent on an adequate liquid head which can be adjusted according izobretengao and adjust the pump via the regulating device. A part of the crushing process is performed after cutting the mined product according to the invention with the aid of a shock wedge, making swing movements, or with a rotary wedge, performing a rotation movement. The mining machine must also ensure that it is possible to install and maintain the required thickness of the mining inlet, i.e. the advancement of the clearing face and the position of the cuts / tdey and the splitting head in height between the roof and the sole. A control device is installed in the mining machine both for adjusting the advancement of the clearing hole with the help of horizontally displaced feeds of 1x elements, and for adjusting the height of the cutting and crushing heads between the roof and the sole with the help of adjusting the elements.

On the machine 2, in the first approach, using nozzles 6 installed in the cutting and crushing heads 3,4, cuts the extracted product in the form of a slit 8 and using a crushing tool 7, also installed in the cutting and breaking heads, dumps it out of the array After the completion of the first inlet, the mining machine 1 moves in the direction of the clearing face and, through the cutting head 4, conducts the next clearing intake, in the opposite direction. In this case, the transportation of the extracted product is carried out by the conveyor 5. This excavation process is carried out by the mining machine until the extraction floor 2 is completely removed.

Due to the rotation of the rotary tube 16, a high-pressure jet of fluid from the nozzle cuts the bottom vertically within an angle of 90-180. This process is possible due to the fact that the axis of the nozzle 6 fixed on the rotary tube 16 is set at an angle between 90-180 ° relative to the longitudinal axis of the rotary tube 16. The pressure of the fluid in the nozzle is necessary for the effective operation of the high-pressure liquid jet. 6 is supported by a regulating device on the bob.
