Definitions

  • the invention relates to a method for controlling a longwall conveyor, at least one mining machine and a hydraulic shield removal having longwall mining operations in underground coal mining.
  • a problem in the automation of long-distance control systems is, inter alia, the control of the cap-to-joint distance, which is referred to below as "KaKo" for short.
  • KaKo cap-to-joint distance
  • it is endeavored in underground coal industry operations to support this Hangend constitutional as soon as possible by appropriate expansion after exposure of a Hangend Structure to reduce the existing reasons of rock mechanics danger of eruption of the hanging in the not supported by expansion area.
  • Hangend Schemeen due to the operation process in the extraction. So first, for example, in cutting extraction with a Walzenschrämlader the shield removal at the coal-thrust end of his Hangendkappe such a distance from Coal thrust that a passing of the scraper blade without collision with the expansion is possible.
  • the invention is therefore based on the object to provide a method of the type mentioned, by means of which the cap-coal joint distance (KaKo) is monitored during the advancement of the face front with a view to minimizing the danger of Ausbruch the hanging wall and is adjustable.
  • KaKo cap-coal joint distance
  • the invention provides in its basic idea that for the controlled compliance of a rock-mechanically favorable cap-coal joint distance by means of at least three of the four main components of each shielding structure as Bodenkufe, broken shield, support arms and fractured area of the Hangendkappe mounted inclination sensors, the slope of Hangendkappe and Bodenkufe in the dismantling direction determined and based on the measured data in a computer unit in case of changes in
  • Inclination angle of the hang-end cap the effects on the cap-to-coal joint distance are determined and an automatic adaptation of the parameters prevailing at screwing, pulling and setting existing working cycle of the shield support frame parameters.
  • the invention has the advantage that initially only due to be determined with a comparatively low effort inclination angle of the individual shield expansion point in the dismantling direction, it is possible to draw conclusions on each setting cap-coal joint distance, in which case in a particular case Affected shield expansion rack whose working cycle when moving or advancing by the computer unit can be set in an automated sequence such that each sets under the prevailing conditions as optimal to be regarded cap-coal joint distance.
  • the inclination of the individual shield expansion point is determined transversely to the degradation direction and compared with the determined bank angle of adjacent shield expansion point and above a value set as permissible during the working cycle an alignment of the respective shield support frame in relation to its neighbor shield extension points takes place. This is to ensure that the individual adjacent shield extension point have no strong differences in their angular position to the longwall conveyor, so do not fall in an automatic sequence, the adjacent shield expansion point from their mutual association.
  • the working cycle can be automatically adjusted or aborted when the shield-building frame moves, so that the position of the individual can be corrected Shielding rack is possible.
  • unwanted misalignments of a shield extension lead to an increase in the KaKo, so that this measure also ensures the mastery of the desired lowest possible KaKo.
  • the hanging end cap is adjusted during every working cycle of the shield support frame in such a way that the wall end cap falls off from its coal-body end to its fracture-end. In such a sloping position of the hang-end cap, a forming mountain pad is stripped off each time the shield support frame moves.
  • This desired position of the shield support frame can also be favored according to an embodiment in that the tilt of the Bodenkufe is set so that an increase in the Bodenkufe to the longwall conveyor results in each working cycle of the shield support, because by a lightly rising in degradation direction runner on optionally on the footing forming heap is favored.
  • This slipping can be due to the induced by the inclination sensors knowledge of the shield position by an am Shield expansion rack in a known manner established lifting device can be brought about specifically.
  • the hanging end cap when determining a change occurring between two working cycles in the slope of the hanging wall in the direction of dismantling the next cycle, is set only with a slope that corresponds to the position of the hanging wall in a previous cycle , The same procedure also results if, after driving under the breakout, the rear, fracture-side end of the hang-end cap pivots into the breakout, which would result in a misalignment of the hang-end cap towards the conveyor. Even in such a case, the hanging end cap is to be set with the predetermined inclination.
  • the height of the extension of the hanging wall-carrying stamp of the shielding expansion frame is detected and the respective altitude of the hanging wallet cap is taken into account for the individual working cycles for determining the required position of the hanging end cap.
  • the setting process of the shield support frame is automatically terminated when the slope sensor tilt indicator indicates a misalignment of the hanging end cap compared to their position in a previous cycle. Furthermore, according to one exemplary embodiment of the invention, provision may be made for a follow-up control set up in the case of a shield support frame to be automatically deactivated for the subsequent work cycle and then reactivated for the subsequent work cycle. These measures prevent misalignments due to the automated setting of shield extension points.
  • the position of the individual shield support frame relative to the longwall conveyor and guided on the longwall conveyor mining machine can be detected is provided according to an embodiment of the invention that the Schreitweg of the retightening of the shield building frame to the longwall effect causing scraper cylinder is detected by a Wegmessvorraum.
  • an inclined sensor is arranged on the longwall conveyor and / or mining machine and the angle of inclination of the longwall conveyor and / or mining machine is determined in the direction of dismantling.
  • the arrangement of an inclination sensor on the mining machine is sufficient.
  • the extraction machine traveling on and guided on the longwall conveyor unit effectively forms a unit with the longwall conveyor, to improve the accuracy of the control, it may also be useful to detect the inclination of the longwall conveyor via a tilt sensor disposed thereon.
  • the arrangement of a tilt sensor differs only on the longwall conveyor for the purpose of control.
  • the difference angle between the footprints of longwall conveyor and shield support frame is determined. With this difference angle is expressed whether longwall conveyor and mining machine on the one hand and shielding scaffolding on the other hand move on a common plane in the degradation direction, or whether a relative position of longwall conveyor with mining machine and shielding structure to each other results due to a change in the seam.
  • the differential angle is less than 180 degrees in the case of a throughput through the throughput, it would be sufficient to exploit the full travel distance of the shield mounting frame which is valid for normal operation Collision with the mining machine, so that it is provided according to an embodiment of the invention that at a detected differential angle of less than 180 degrees of the path of the shield support frame to the longwall conveyor during the work cycle is reduced such that a passage of the mining machine before the coal side cap tip of the hanging end cap is possible.
  • the KaKo is undesirably increased due to the position of the longwall conveyor and mining machine and shield support frame, so that in this case the advance of longwall mining conveyor with the mining machine is reduced in order to limit the KaKo.
  • the return path of the longwall conveyor to the coal thrust out at advanced Schreitausbaugestell and thus the cutting width of the extraction mesh is reduced such that the passage of the mining machine in comparison with the normal cutting width of the mining machine sets lower cap-to-chip-gap.
  • longwall equipment comprises first a shield support frame 10 with a bottom skid 11 on which two punches 12 are attached in a parallel arrangement, of which in FIG. 1 only one stamp is recognizable and carry a hanging end cap 13 at its upper end. While the Hangendkappe 13 protrudes at its front (left) end in the direction of the still to be described extraction machine, at the rear, right end of the Hangendkappe 13 a breaker plate 14 is articulated by means of a hinge 15, wherein the broken shield of two in side view on the Bodekufe 11 resting support arms 16 is supported.
  • three inclination sensors 17 are attached to the shield support 10, namely, a tilt sensor 17 on the bottom skid 11, a tilt sensor 17 in the rear of the hanging end cap 13 near the joint 15, and a tilt sensor 17 on the fracture shield 14.
  • the support arms 16, also a tilt sensor, of the four possible tilt sensors 17 three inclination sensors must be installed in order to determine the position of the shield support frame in a working space with the determined slope values to determine.
  • the invention is not limited to the concrete in FIG. 1 illustrated arrangement of the inclination sensors limited, but includes all possible combinations of three inclination sensors to the four moving parts of the shield support frame.
  • FIG. 1 illustrated shield support frame 10 is struck on a longwall conveyor 20, which also has a tilt sensor 21, so that in terms of the control of the longwall equipment in general also here data regarding the conveyor position can be obtained.
  • a recovery machine in the form of a Walzenschrämladers 22 is guided with an upper roller 23 and a lower roller 24, wherein a tilt sensor 25 is disposed in the region of the Walzenschrämladers 22, further, a sensor 26 for detecting the respective location of the Walzenschrämladers 22 in Strut and reed rods 27 for cutting height measurement.
  • FIG. 2 results, the use of the in FIG. 1 described longwall equipment in a long-distance operation in such a way that the longwall equipment is moved to the horizontal 31, wherein the rollers 23 and 24 of the Walzenschrämladers 22 win the coal thrust 32.
  • the hanging wall 30 is supported by the hangover cap 13 of each shield support frame 10, whereby with increasing Verhiebieb the hanging wall 30 falls as a break 40 after Streb trimgang.
  • the KaKo 33 then increases when forms on the hanging wall 13 of the shield support frame 10 a mountain pad 35, which forms the support for the hanging wall 30.
  • a bulge 36 in The area of the upper bank of the coal thrust 32 occurred, and it can be seen how, without a fundamentally different position of the longwall equipment in comparison with FIG. 2 a much larger KaKo 33 results, so that the outbreak-prone area 34 increases significantly.
  • FIG. 4 It can be seen that with a continuously set inclination of the hanging wall 13 with a drop from its coal-body end towards the fracture side 40 during the walking process, a forming mountain pad 35 is stripped respectively. At the same time, it can be seen in the region of the bottom skid 11 that the bottom skid 11 is to be set towards the longwall conveyor 20 with a slightly increasing angle in the direction of dismantling 38, since this promotes slipping on heaps lying on the horizontal 31.
  • These measures can be implemented in detail by arranged on the shield support frame 10, but not shown in detail corner cylinder between the hanging wall 13 and the shield 14 and by a known lifting device in the region of the bottom skid 11 (so-called. Baselift).
  • FIGS. 5 to 7 Now the passage of the longwall equipment is represented by a Hangend Scheme with an outbreak 37. This is off FIG. 5 It can be seen that in the event of an outbreak 37 that has occurred, there is the risk that the coal-body-side end of the hanging-end cap 13 will fit into the break-out 37, and this process can be detected on the basis of the tilt sensor 17 attached to the hanging-end cap 13. As a further identification feature for the presence of an eruption in the hanging wall can also change the altitude of the hanging wall 13 by determining the extension height of the punch 12, for example via the arrangement of corresponding sensors 18 on the punches 12, used become.
  • the Hangendkappe 13 is the breakout 37 underneath, as shown in FIG. 6 is shown in principle.
  • FIG. 8b results in the approach of a trough ( FIG. 8b ) to a tilting position of longwall conveyor 20 and mining machine 22, which is detectable on these arranged tilt sensors 21 and 25, respectively.
  • the inclination values recorded here can be contrasted with the inclination values recorded on the shield support frame 10, and this results in a differential angle that can be related to the respective contact surface of the walking frame 10 and the longwall conveyor 20 with mining machine 22 on the horizontal 31.
  • FIG. 8c A reverse situation arises in a Saddle, as this in FIG. 8c in comparison with FIG. 8a is shown.
  • the shield support frame 10 is pulled to the full path of passage forward, but that the cutting width of the mining machine 22 is withdrawn.
  • shielding station 10 are also known, which have a Ausstellschiebekappe 41 in the area of their Hangendkappe 13.

  • the requirements for mastering the cap-coal-butt distance in an automated operation of the shield extension can also be improved by the fact that constructive changes to the shield extension points can be carried out in over-day repair and maintenance. This also applies, in particular, to new designs of shielding outgoers, in which the requirements of the automated removal operation can be taken into account from the outset.
