The invention relates to a mining machine for quarrying, moving along a conveyor installation of the machine frame, which in the operating mode on its facing the front of the treatment works the front side in all directions the movement has pneumatic tools for mineral produced and installed on the machine frame sensor system for detection of minerals/rocks. Further, the invention relates to a receiving device for sensor systems for detection of minerals/rocks during mining operations using moving along the conveyor system of the mining machine.

Underground workings has long been known method for improving the performance Oistamo the slaughter of mining machines in the development of mineral resources due to the fact that by means of an appropriate sensor system probe the boundary layer between rock and soil extracted mineral, such as coal, through rock cutting tools, mining machines, in particular, on the underlying layer to produce almost exclusively mineral. Known sensor systems consist almost exclusively of optical sensor systems, which by means of suitable clamping elements (springs) are pressed against by the ode soil, to optically probe differing reflectivity of coal, on the one hand, and breed in the soil, on the other hand. Only by way of example in patent publication DE 199 25 949 A1 indicates that the optical touch system as a comprehensive replacement node is installed with the possibility of vertical movement in the receiving box, which by means of sliding bolts fixed in the recess on the front side of the machine frame of a coal plow and bottom freely lying on the ground. In the coal plow specified first kind, on top of the touch device is a roofing tool, with which you can change the height of the excavation of the site of the mining machine. Known optical sensor system in terms of the structural design can probe the boundary layer only in the area bedrock.

The objective of the invention is to create a mining machine which can be equipped with a sensor system, respectively, can be used.

This and other problems are solved according to the invention by the fact that on the front side of the machine frame fixed speaker receiving box for sensor systems, while in the receiving mailbox is set as the sensor system preferably GPR. Due to the speaker mounting of the receiving box can not only use the AMB other sensory systems, in particular, GPR, but at the same time created the basis for what can be explored the entire front of the treatment works not only the boundary layer between the bedrock and the extracted mineral raw materials. Acting fastening provides a direct, essentially optimal “overview” of the entire front of wastewater treatment works, while using the touch system can be explored front of wastewater treatment works throughout the area, as from the front and from the side of the stope before expensive machine in the lava on the conveyor until the console upper overlapping shield of powered roof supports.

In a preferred embodiment, GPR and/or the receiving box installed in the middle between a rock cutting tools. This may be determined by the number and the angle of radiation of the touch device in which the front zone of treatment works necessary to carry out the sensing of the boundary layer between minerals and host rock, with an all-touch device installed with protection in the receiving space of the receiving box. GPR is applicable in principle for use in mining machines operating in the planing mode, and for use in mining machines operating in the mode of extraction. The main scope of the present invention relates, however, to mining Masha who am, in which Portorosa tools are cutting drums, that is, in particular, relates to harvesters with drum Executive body for the coal.

For numerous target assignments may be sufficient, if the receiving mailbox is mounted in a rigid position on the front side of the machine frame. As for height-adjustable rock cutting tools, in particular height-adjustable rock cutting tools respectively ahead at the front side of the mining machine, it may be, however, favorable, if the receiving box can be adjusted in height or be attached to the machine frame at different levels in height.

In particular, in the preferred embodiment, the receiving mailbox is made of several parts and includes receiving GPR main box with holes type boxes below and/or above, while on either side of the main box set of deflecting elements. Then the receiving box can be made as a closed receiving mailbox from which you want to derive mainly from the backside only the signal and supply lines for sensor systems, meanwhile, both deflecting element serve to protect the main box and eliminate the ingress to the primary mailbox breaking rocks or repulsed mountain mA the son.

The above problem for a receiving device for the touch system is solved in that the receiving device consists of made of several parts of the receiving box for GPR and can be removable attached to the forward protrusion on the front side of the frame of the mining machine. When this receiving box preferably includes a main box under the radar with holes type boxes below and/or above and also installed on both sides of the receiving mailbox deflecting elements.

Suitable holes type of Windows to run in the wall of the cover and/or the bottom wall of the main box, which are respectively inclined relative to the rear wall of the main box, to using a touch device, GPR, which is placed in the main box, to probe the front of the sewage treatment works in the area of bedrock and, if necessary, in the area of the roof. The Windows are preferably closed to GPR interchangeable display panels, in particular plastic panels to electromagnetic waves touch devices GPR could probe the front of the treatment works, on the one hand, and to ensure unimpeded reception of the emitted waves touch devices. In the event of excessive wear indicator panels they can be replaced with new flat panel.

In especially preferred is entrusted embodiment, the main box is made elongated and/or closed trapezoidal side walls and a rectangular front plate. Due to the trapezoidal shape of the receiving box is relatively small resistance relative to the smitten rock mass, etc. while at the same time also in the main drawer is provided with a deflecting function. Mainly deflecting elements consist of a back plate, a few ribs and trapezoidal connecting walls, which are welded to each other, forming a stable welded construction. The upper and lower ribs deflecting elements are preferably inclined relative to the back plate and, in particular, in line with the wall of the bottom and wall of the cover main mailbox. If the deflecting function in the case of extracted mineral cannot be fully implemented, respectively, due to the simple set of deflecting elements, each deflecting element may be additionally equipped with the appropriate cutting timber, if necessary, remaining in the direction of movement behind the rock cutting tools material to be cut passes in the direction of movement of the cutting beam. Each deflecting element can be equipped as well as additional wear protection running on the wear plate or hardened boundary layer.

Further, the rear wall preferably can extend beyond a wall of the cover and the wall of the bottom or soo is laid back plate for the upper and lower plate stiffness, up or down the strap with the screw holes, so that a relative simple way to fix the receiving box with a protrusion on the machine frame. Into the holes indicated strap during installation of the receiving box on the mining machine is screwed preferably the locking screws, if necessary together with the adjusting pins are used for the perception of longitudinal and transverse forces and simultaneously form a space of a given fracture between the machine frame, on the one hand, and the receiver's mailbox, on the other hand.

Other advantages and embodiments of the mining machine according to the invention and a receiving device according to the invention made it clear from the following descriptions are schematically shown on the drawing of the example implementation. The drawing shows:

Figure 1 shows the system graphicsconfiguration underground longwall face 1 for coal mining. Cleaning the face 1 support open by hydraulic mechanized shield roof support 2 between the so-called lying sideways 3 and hanging sideways 4. Below the upper overlapping 5 shield mechanized lining 2 is a conveyor such as a chain scraper conveyor 6, which produced the harvester 10 with the drum by the Executive body as a mining machine, mineral, particularly coal, is transported from the lava. The harvester 10 with drum Executive body includes a machine frame 11, the back side 12 which is turned to mechanized shield roof support 2, that is, to the filling side, and its front side 13 facing the front 7 of the treatment works. As rock cutting tools harvester 10 has, as shown in figure 2, two of the cutting drum wheels 14, 15, which are supported by an appropriate bearing or pivot arm 16 or 17 on the machine frame 11. The machine frame 11 rests by means of several guide devices, for example the front guide shoes 18 on the conveyor 6, and simultaneously, at least one drive gear wheel 19 near the rear side of the machine frame 11 is engaged with the mounted on the conveyor 6 by the feeding device, for example a toothed rails 8, as is known to the expert in the field of underground mining. Due to the possibility of turning the Wallpaper is cutting drum wheels 14, 15 on the rotary levers 16, 17 may be provided that are appropriate ahead in the direction of movement F of the drum wheel 14 divides the ledges in front of the sewage treatment works on the roof, and the rear drum wheel 15 in the transition of the roof to the underlying rocks, 3. The rotary position of both drum wheels 14, 15 are adjusted so that overlaps the entire height of the machine frame 11.

To ensure optimal detection of the indicated position 9 in figure 1 of the boundary layer in the zone of the bedrock, and if necessary also of the boundary layer in the area of the roof using the appropriate sensor system, on the front side 13 of the machine frame 11 of the harvester 10 with drum Executive body attached to the protrusion of the receiving box 20 for room details not shown GPR as a sensory system, so that at least prestuplenie boundary layer 9 in the transition front of wastewater treatment works 7 to underlying rocks 3 can be explored by means of radiated electromagnetic waves And GPR in the receiving box 20. For recognition of the host rock evaluate the characteristics of the refraction and diffraction at the boundary layer 9 by varying degrees of absorption or reflection R of minerals and rocks. The receiving module sensor systems can receive the reflected signals R, ctobin the basis of their record information about the boundary layer, and Geology bedrock 3. The sensing of the boundary layer on the roof can be performed by other sensory devices. Acting fastening the receiving box 20 with unobstructed “review” front wastewater treatment works 7 serves as a guarantee that the emitted touch system in the receiving box 20 electromagnetic waves fall solely on the extracted mineral rock or host rock, despite the fact that none of the nodes/elements combine with drum Executive body cannot prevent it.

Figure 3-5, which further reference, it is shown the preferred embodiment of the corresponding receiving box 20 according to the invention, which is GPR. Indicated generally at 3 and 5 position 20 of the receiving drawer not shown for GPR as the sensory system is made of three parts and contains elongated in the length of the average main box 21, both sides of which are made identical deflection elements 30. The main box 21 in which are located one or more sensory devices to the radar system, including antennas, power line and signal line, etc., consists of a solid back wall 22, sidewalls 23 of the bottom and wall of the cover 24, which are respectively inclined relative to the rear wall 22, two trapezoidal lateral stenok, and the front wall 26, which are welded to each other, forming an essentially closed housing. The receiving box 21 in length more than two times the width and, in particular, the front wall 26 consists of a rectangular rack plate. The wall 23 of the bottom, as well as the wall 24 of the cover main box 21 are tilted to each other and narrow, thus, the width of the receiving box 21 as the distance from the back wall 22. The wall 23 of the bottom is in the center of a rectangular, relatively small hole 27 type of window. The wall 24 of the cover due to the relatively large rectangular opening 28 is made almost entirely in the form of a narrow frame jumper that allows, if necessary, in the mounted position of the suction box 21 through a large opening 28 to provide repair or replacement located in the receiving space 21A of the receiving box 21 touch devices GPR. A relatively large opening 28 is closed by the closing plate 50 made of metal, which is supplied, in turn, a relatively small hole 29 of the type of window, the dimensions of which correspond exactly to the dimensions of the holes 27 of the type of window in the wall 23 of the bottom. The hole 27 of the type of window oriented in an inclined wall 23 of the bottom provides through touch devices GPR free “overview” front wastewater treatment works in the area of the underlying on the odes, and the hole 29 of the type of window oriented in an inclined wall 24 of the cover main box 21 provides an unobstructed view of the boundary layer on the roof. Both openings 27, 29 type of window for tight locking of the receiving space of the receiving box are closed by appropriate protective panels 40, in particular plastic panels, which in the case of excessive wear can be replaced with other plastic panel and, for example, on ledges 27A, 29A inside the holes 27, 29 type of window can be fastened with screws or fixed in another way. The rear plate 22 of the main box 21 strap 22A with the screw holes is respectively as against the inner wall 23 of the bottom and the wall 24 of the cover up or down, and both of these strips 22A provided with a corresponding number of threaded holes 41, which makes it possible to tightly screw in the whole ten fixing or lingering screws main box 21 with the machine frame 11, as shown, for example, in figure 4. For additional fastening at the rear side of the rear wall 22 may be placed expanding pins, and/or the rear wall contains or forms a resistant slats are flush interact with the protrusions or recesses in the front side of the Shearer drum-Executive body that allows you to securely accept all affecting the operating mode on the main box 21 efforts. Supply cables to the sensor device in the receiving space 21A of the main box 21, as well as other hydraulic lines or the signal lines and the like through the opening 22B in the rear wall 22 of the main box 21, thus opening 22B preferably is about across the surface of the main drawer, which is GPR.

To protect the main box 21 GPR as a touch system from damage and tear, despite his advanced open mount on the front side of the machine frame, on the sides of the main box 21 mounted in both directions of movement of the deflector elements 30. Both deflecting element 30 consists of a solid rear plate 31, here a total of four ribs, namely the upper rib 32, the lower the rib 33, and two medium perpendicular to the rear plate of ribs 34, which are made essentially triangular and cross-side welded to the weld, perpendicular to the rear plate 31 trapezoidal connecting wall 35. The upper and lower ribs 32, 33 are tilted relative to the back plate 31, at the same angle as the wall 23 of the bottom wall 24 of the cover in the main box 21, so that in the installation position, as shown in figure 3, they lie on the same line with the last. Deflecting elements 30 increase the Xia wedge from the free end to the connecting wall 35, which in the installation position adjacent to the side wall 25 of the main box 21 and svinina with it by means of clamping screw 43. The rear plate 31 also acts as a strap with the screw holes 31A, respectively, for the upper rib 32 up or down of the rib 33 down that can be used to mount both deflecting elements 30 to the machine frame by an appropriate number of protracted screws 42, there is generally six protracted screws 42. Also for both deflecting elements 30 may be provided for expanding the pins and the like, in order to reliably perceive the total effort along and across the direction of movement. However, it is favorable if the locking screws 42, as well as optionally available expanding pins form a space of a given fracture, to ensure the collapse of the entire receiving box 20, together with the deflector elements 30, in the event of a blockade between the receiver box and fragments of rock, which accordingly allows to avoid more serious damage to the harvester with the drum by the Executive body or in the guiding device for the specified processor. In the event of an accident would require only the installation of a new receiving box 20.

In the example shown the implementation of the deflecting elements and the main box is fixed in position on the machine frame. On ICIE sets arranged one on top of the other bars with the holes in the machine frame also could help with the rest of identical design to the reservoir lower power. The regulation height of the receiving box can be made by fastening the receiving box on the main plate and different positioning of the base plate on the front of the harvester with the drum by the Executive body. The example in figure 1 shows the sensing front of the sewage treatment works on the underlying rocks by GPR. Alternative means of GPR can probe only the roof or equally as the roof and the ground. GPR is set preferably within a pressure-resistant, intrinsically safe housing, and with it placed in the main mailbox. The main box can be mounted on the front side of the mining machine also by welding or other means. Instead of one main mailbox for one or more radars on the front side can be fixed also some top boxes, while deflecting elements in this case are preferably on the sides of all the main boxes. Such and other modifications fall within the scope of protection of the attached claims.
