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 method of the aforementioned type is in the DE 196 36 389 A1 described, in which a load control of the shield removal point is provided, in which the critical load cases "unilateral load” and / or “peak dance” detected during the setting process using appropriate sensors and rendered harmless by appropriate control of the hydraulic punch and / or a corner cylinder in their impact become.
  • sensors are arranged on the components of the shield-mounting frame whose electrical measured values are used by a control unit for evaluating the measuring signals and for controlling the hydraulic punches and / or the corner cylinder assigned to the shield-mounting frame.
  • Controlling struts during pillage is generally about making the best possible use of the resources provided Machine capacities while avoiding stoppages, where possible, an automation of the necessary control operations should be given to avoid erroneous human decisions.
  • Approaches to automation of the controller are in development or already in use, such as sensory boundary layer detection / control, learning step method, detection and control of the way back of the walking structure, automated pacing of the walking structure and automatic compliance with a predetermined nominal inclination of the longwall conveyor.
  • the invention is therefore based on the object to show a method of the type mentioned above, which gives indications of a possible collision between the mining machine and the shield support frame and thereby helps to avoid corresponding collisions.
  • the invention provides a method in which inclination sensors mounted on at least three of the four main components of each shield support structure such as bottom skid, breaker shield, support links, and fractured section of the hangum cap determine the inclination of the shield components against the horizontal in the direction of travel and from the measured data in a computing unit by comparison with the stored therein, the geometric orientation of the components and their movement during walking defining basic data, the respective banking rights height of the shield support frame is calculated at the front end of the hanging wall as a measure of the longwall.
  • the invention initially has the advantage that solely due to the geometrical conditions to be determined with a comparatively low outlay when using the shield extension, the front end of the hanging wall can be determined in the form of the bank-legal height determined for this point; as long as this Strebö réelle the produced by the mining machine during their scheduled operation Strebö réelle corresponds or is slightly larger, there is no risk of a collision of the mining machine with the relevant Schildausbaugestellen. If the constant monitoring of the longwall opening at the front end of the hang-end cap results in a too small bracing opening, an impending collision can be counteracted by a corresponding activation of the mining machine.
  • the data obtained at individual shield extension points provide additional information about the behavior of individual sections of the front panel or the entire front panel as the penetration progresses, which enables integral process control of the respective mining operation.
  • Adjustment limit of the shield extension in a targeted automatic operation threatens.
  • the danger of a landing of the hanging wall then exists when entering the convergence of the shield temples are completely retracted and due to the then overburdening wall hanging the shield expansion block is blocked and can not be brought forward;
  • Another possibility is that the steel construction at the lower Verstellalia in Lemniskatengetriebe the shield support frame or in the joint hanging end cap / rupture shield blocked and then can not be brought forward.
  • the above moments of danger apply in particular to the passage of saddles or depressions in the course of the seam, which can be accommodated by a corresponding device of the recovery height of the respective recovery machine used.
  • the corresponding face opening data can provide information about a possible fall from the hanging, the occurrence of seaming, the "on-coal driving" give the mining machine or a possible lying incision of the mining machine.
  • Schildausbaugestelle be used in a design with divided Bodenkufe in which between the two single skids the walking mechanism of Schildbausbaestestells is arranged so that the two individual runners of Schildschild rack are in contrast to interconnected runners segregated from each other separately can, whereby the so-called Elephant Step is possible as a step control.
  • the so-called Elephant Step is possible as a step control.
  • Shield extension points on each individual skids one inclination sensor is arranged.
  • the respective height of the shield is calculated from the measured angles of inclination for the hangover cap, the breaker plate and for the right and left individual skids of the shield support frame, it being possible to provide that the height of the shield determined for the shield support frame the mean value of the height values calculated for the two individual skids is calculated.
  • a single evaluation of the height of the sign is required for the right and left half of the sign based on the inclination angle determined on the single runners.
  • the inclination sensors attached to the shield components are placed at locations with a minimum bending angle of the components, this serves to minimize measurement errors under load.
  • the stamp of the walking frame is determined by means of pressure sensors of the internal stamp pressure.
  • a correction factor taking into account the bending load in practical use of the longwall support station can be used as a function of the respective load recorded during operation, as provided according to an exemplary embodiment of the invention.
  • the inclination of the hanging end cap against the horizontal, transverse to the direction of travel is ascertained via the inclination sensor attached to the hanging end cap of the shielding structure.
  • the screwing height of the hanging end cap may be reduced, or the hanging end cap in the dressing may be aligned with adjacent shild support points prior to the shearing cycle, or the shearing cycle may be discontinued prior to re-setting the shingling frame concerned if that shim assembly has fallen out of the association; then there is also a correction.
  • the determined for a shield frame position associated with the extraction machine roller cutting height is assigned by means of a location-synchronous evaluation of the temporal expansion delay of the hanging wall of the associated shield expansion rack determined for this position Strebö réelle.
  • expansion delay the fact is taken into account that the Strebö réelle made by the mining machine is reached from the top of the hanging end cap of the associated shield support frame until one or two expansion steps later, which is referred to as expansion delay.
  • the height data can be used at one and the same location.
  • historical cutting height data are set in the mentioned arithmetic unit and set in the comparison with the shield data at the same spatial coordinate as soon as the shield expansion frame has reached the corresponding spatial coordinate. This procedure can also be referred to as location-synchronous evaluation.
  • the control method according to the invention is further improved by determining the inclination of the conveyor and / or mining machine against the horizontal in the direction of travel of the shield extension by means of inclination sensors attached to the conveyor and / or mining machine.
  • the arrangement of an inclination sensor on the mining machine is sufficient.
  • the mining machine carried on and guided by the walkway conveyor is, so to speak, integral with the longwall conveyor, to improve the accuracy of the control, it may be convenient to also detect the slope of the longwall conveyor via a tilt sensor disposed thereon.
  • the arrangement of an inclination sensor only on the longwall conveyor for the purpose of the control also sufficient.
  • the angle of inclination of conveyor and / or mining machine set in relation to the determined at the bottom of the skid frame and / or Hangendkappe tilt angle and the differential angle formed in the calculation of the case of several consecutive Schreitzyklen the Schildausbaugestells adjusting Strebö réelle is included.
  • the height values describing the geometry of the shield support frame are recorded at the front end of the hanging end cap, in the region of the starting point of the punches on the hanging end cap and in the region of the hanging wall end cap and shield cap over the time axis, and from changes in the measured values over the time axis the convergence caused by the loading mountain is determined.
  • Convergence is the decrease in the height of the respective longwall opening in relation to the initial height. From the shield replacements deployed, the convergence of a single rack can be determined from step to step at each location where the shield rack has been deployed.
  • the temporal course of convergence is decisive.
  • the position of the shield support frame with respect to the initiation of expansion support forces is determined by the position of the Hangendkappe to the course of the hanging on the position of the breaking edge is closed over the hanging cap. In this way, technically unfavorable positions of the shield support frame can be detected and taken into account and corrected accordingly in subsequent cycle cycles.
  • acceleration sensors are used as inclination sensors which detect the angular position of the acceleration sensor in space via the deviation from the gravitational acceleration.
  • the measured values ascertained by the acceleration sensors are checked and corrected by means of a suitable damping method.
  • the position of the individual shield extension is made visually visible in a display unit, wherein it can be useful if recognized as a risk deviations from predetermined target values in the display unit are displayed in a conspicuous color ,
  • 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 crash plate 14 is articulated by means of a hinge 15, wherein the broken shield of the two in the side view on the Bodenkufe 11 resting support arms 16 is supported.
  • three inclination sensors 17 are mounted in the illustrated embodiment, namely a tilt sensor 17 on the Bodenkufe 11, a tilt sensor 17 in the rear of the hanging wall 13 in the vicinity of the hinge 15 and a tilt sensor 17 on the fracture shield 14.

  • the Bodenkufe 11 consists of two partial skids, which are, however, firmly connected to each other via a solid steel structure 28, so that there is a so-called “tunnel skid".
  • this tunnel skid has a better height mobility, but it comes to higher surface pressures and thus to a higher tendency to sink the two skids in the lying.
  • the Bodenkufe be formed with two partial runners, which are connected to each other via a bottom plate 29, so that there is a larger bearing surface for the Bodenkufe.
  • the surface pressure and thus the tendency is reduced that the Schildausbaugestelle in particular in the area of the tip tip in the Push in lying down.
  • this design limits the mobility for rapid changes in the height of the sign, because in particular at a rapid increase in the height of the sign, the stepping 37 can not follow a fast emerging longwall conveyor, because the walker then abuts the closed floor panel 29, which limits the possibility of height adjustment.
  • FIG. 8c an embodiment is shown, which is preferably used in planing operations at a low seam thickness, such as below 1.5m.
  • separate individual runners 35 and 36 are provided, between which the walking mechanism 37 is arranged such that the right-hand runner 35 in the direction of travel can be lifted independently of the left-hand runner 36 in the walking direction.
  • This separation of the individual runners 35 and 36 allows the steps of the shield support frame 10 in the so-called Elephant-Step, by means of which a sinking of the two single skids 35 and 36 in the horizontal 23 and accumulation and postponement of debris in front of the individual runners 35, 36 can be counteracted.

Furthermore, a Wegmesssystem 19 is integrated in the Bodenkufe 11, by means of which the respective Schreithub the shield support frame 10 in relation to the longwall conveyor 20 can be determined.
  • the arrangement of the inclination sensor 21 on the longwall conveyor 20 is not absolutely necessary as long as the inclination sensor 25 is set up on the drum skid loader 22. In such a case, however, the inclination sensor 21 may be additionally provided to improve the measurement accuracy.
  • the shield support frame 10 can be due to the known kinematics of the shield support frame 10 depending on the position of Bodenkufe 11, 14 Bruchschild and Hangendkappe 13 to each other determine the heights h 1 , h 2 and h 3 , wherein the height h 1 for determining the bank level height of the longwall 30, while the height h 2 is a measure of a possible overhang in a fully extended shield frame stand or for annensetzergefahr, while the height h 3 can be used to consider the convergence.

  • shielding expansion frame 10 In the position determined by the values of the tilt sensors 17 in FIG. 6 illustrated shielding expansion frame 10 is the breaking edge 35 in the rear region of the hanging wall 13, which means that the load capacity of the shielding rack is optimally utilized, because the introduction of the expansion forces in the area of the shielding rack takes place, in which the best possible effect can be achieved with respect to the hillside control. Eventual, on the surface of the Hangendkappe 13 forming mountain upholstery can be stripped when walking the shield support frame 10. The Bodenkufe stands slightly rising and can thus slide well on possibly on itself on the footwall 32 forming heap. The result of such a position of the shield support frame 10 is that hardly any debris is to be expected when advancing the expansion, so that optionally also an automatic and trouble-free operation of the longwall equipment is possible.
