Definitions

  • the invention relates to a mining device according to the preamble of independent claim 1.
  • Such mining devices which comprise tensioning means for reversibly tensioning the mining device in a cavity, a frame and propulsion means fixedly connected to the tensioning means, the frame being movable in a predefined direction by the propulsion means, can be used for underground mining of raw materials from rocks Creation of studs.
  • the rock strata to be degraded are typically accessed via access tunnels or a network of access tunnels.
  • the actual mining is done today mostly by blasting in the degraded rock layer and subsequent removal of the mining material for triage and re-use.
  • Such explosions are always the cause of accidents and are therefore subject to high safety requirements, which are regularly monitored.
  • the mining pits and the The access tunnels were cleared before the blasting, which entails considerable logistical costs and completely interrupts the dismantling in stages.
  • the extent of the degradation is difficult to narrow in explosions, so that either rock is mined, which is adjacent to the degraded rock layer and thus contaminated the decomposition material, or so that remains of the degraded rock layer remain and will not be degraded.
  • the company VOEST-ALPINE BERGTECHNIK sells under the product name ARM 1100 a mining device comprising a frame on which a pivoting arm is arranged, which can be driven in relation to a tense with a stud part of the mining device.
  • a rotating Schrämusion is arranged, which has arranged on its front side along its edge cutting discs.
  • the swivel arm is included Rotated Schrämrad pivoted back and forth, which is the rock, which comes into contact with the Schrämrad in contact is reduced.
  • a substantially rectangular mining cross-section can be generated with the aid of the swivel arm.
  • no continuous degradation over the entire mining cross section is possible, whereby the degradation productivity is limited.
  • the object of the following invention is therefore to propose a mining device which generates a substantially rectangular mining cross-section and enables continuous mining.
  • the mining device comprises tensioning means for reversibly tensioning the mining device in a cavity, a frame and propulsion means fixedly connected to the tensioning means, wherein the frame is movable in a predefined direction by the propulsion means.
  • tensioning means for reversibly tensioning the mining device in a cavity
  • a frame On the frame a rotatable roller is arranged, on the circumference of cutting tools and reamer are arranged.
  • Such a mining device allows a simple way of degradation of Rocks including a substantially rectangular mining cross-section, which among other things, on the one hand enables efficient targeted degradation of a raw material-containing rock layer and on the other hand can produce a tunnel, which has an advantageous shape.
  • the roller of the mining device is in contact with the entire mining section substantially continuously, allowing productive continuous mining.
  • This mining device further allows the frame to be moved by the propulsion means both straight ahead and around a horizontal or vertical curve.
  • At least one edge cutting tool is arranged on the circumference of the roller such that it projects beyond the roller in the axial direction at least when the roller is in a rotational position in which the edge cutting tool is located on a side of the roller facing away from the bracing means.
  • at least the frame of the mining device projects beyond the roller in its axial direction, which makes it impossible for the frame to be displaced into the mining pits produced by the mining device.
  • the mining cross-section beyond the cross section of the roller can be increased so that the frame and any other subsequent devices can be moved in the generated mining tunnels.
  • the at least one edge cutting tool is arranged so that it is folded out in the axial direction of the roller, when the roller is in a rotational position, in which the edge cutting tool is located on a side facing away from the bracing roller, and that it is collapsed, if the roller is in a rotational position in which the edge cutting tool is located on a side of the roller facing the bracing means.
  • the edge cutting tool is unfolded, whereby it can be achieved that the excavation cross section is large enough to allow a roll projecting frame, moved into the mining rollers to become.
  • the edge cutting tool is folded, which can be prevented that it collides uncontrollably with the frame and impairs the rotational movement of the roller.
  • two rollers are arranged in parallel, wherein the axis of rotation of the one roller is in line with the axis of rotation of the other roller.
  • Such rolls allow a relatively simple construction to provide a mining cross section of a given thickness. You can do it both at an intermediate and at one be arranged outside frame. In this case, it is particularly advantageous if at least the region of the excavation cross section between the rolls or away from the rolls is enlarged by foldable edge cutting tools as described above.
  • two rollers are arranged with their sides facing each other at an acute angle to each other, so that the rotational axis of the two rollers enclose an obtuse angle.
  • the sides of the rolls facing the rock to be excavated are maximally spaced from one another, while the sides of the rolls facing the propulsion means are minimally spaced from each other.
  • Such an arrangement of rollers allows the use of edge cutting tools that are not hinged while providing a sufficiently large excavation cross section for moving the frame and other equipment into the mining pits.
  • the two rollers each have a peripheral cutting tool which projects beyond the associated roller in the direction of the other roller.
  • a consistently defined mining cross section can be achieved in particular in the area between the rollers.
  • the two rollers may each have at least one further edge cutting tool, which is the associated roller in the direction surmounted by the other roller away.
  • the cutting tools and the at least one edge cutting tool of a roller are arranged alternately to the cutting tools and the at least one edge cutting tool of the other roller.
  • each with at least one of the associated roller in the direction of the other roller superior edge cutting tool can thus be ensured that the said edge cutting tools of a roller overhang the other roller at the minimally spaced location of the two rolls, without Cutting tools or edge cutting tools of the other roller to collide.
  • the two rollers are preferably rotatable in the same direction, which allows a simplified construction of the rotational drive of the rollers and a simplified removal of the excavation material.
  • the cutting tools and the at least one edge cutting tool may comprise cutting rollers. With such cutting rollers, a high degradation productivity can be ensured even in hard rock.
