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.
  • KaKo cap-coal-collision distance
  • mining operations inevitably lead to slope areas without development support Extraction with a roller cutter the shield removal at the coal-thrust end of his hanging end cap 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 Slope angle of the hang-end cap the impact on the cap-to-butt joint distance will be determined and an automatic adjustment will be made of the parameters prevailing at screw-in, pull-out and set duty cycle of the shield support frame.
  • the invention has the advantage that initially alone due to be determined with a comparatively low effort inclination angle of the individual shield expansion point in the degradation direction, it is possible to draw conclusions on the each adjusting cap carbonization distance, in which case in a particular case Affected shield expansion rack whose working cycle when walking or pulling by the computer unit in an automated process can be set so that each adjusts under the applicable conditions as optimal to be regarded cap-coal joint distance.
  • the inclination of the individual shield expansion point is also determined by the inclination sensors 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 process, 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.
  • 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 automatic finishing work is made more difficult in those cases where the shield extension are equipped with a so-called Nachsetz horrung.
  • This Nachsetz horrung automatically ensures a setting of the shield support frame f until the Hangendkappe against the hanging wall pushing stamp have reached a working pressure of, for example, 300 bar. In the presence of outbreaks or sagging Hangend Geben this means that the Nachsetz horrung automatically presses the hangover cap until a correspondingly fixed resistance has set.
  • 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 its 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.
  • the position of the individual shield support frame relative to the longwall conveyor and guided on the longwall conveyor mining machine can be detected, according to an embodiment of the invention provides that the path of the pulling the Schildausbaugestells causing the longwall conveyor Schreitzylinder 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 distance.
