Definitions

  • the invention relates to a mining device according to independent claims 1 and 3.
  • 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 takes place today mostly by means of 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 tunnels and the access tunnels are cleared away before the blasting, which entails considerable logistical costs and completely interrupts the exploitation in stages.
  • the scope 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 are not degraded.
  • tunnel boring machines are often used in the underground mining of rocks for the construction of tunnels.
  • a tunnel boring machine shown which has a horizontally arranged, drivable in a predefined direction and slightly inclined in this direction of advance rotatable roller.
  • cutting tools oriented substantially in the advancing direction and in addition, cutting tools oriented substantially perpendicular to the advancing direction are arranged on the upper side of the roller.
  • JPH03262898 also a tunnel boring machine is disclosed, with a rectangular cross section can be moved up.
  • a plurality of superposed mining tools for releasing the rock are provided, which are designed as rollers or like a roll with arranged thereon mining tools.
  • mining equipment is also sometimes used today for the extraction of raw materials from underground, which can significantly improve the reliability with which the number of interruptions of the mining can be significantly reduced and with which the raw material-containing rock layer can be reduced more efficiently targeted, i. ideally including a rectangular mining section.
  • 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 In operation, the swivel arm is pivoted with rotating Schrämrad back and forth, whereby 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.
  • a rotatable roller is arranged, on the circumference of cutting tools and reamer are arranged so that a substantially rectangular excavation cross section can be generated and the mining device and in particular the frame of the mining device is movable in a mining tunnel generated by these cutting tools.
  • Such a mining device allows in a simple manner a degradation of rock to include a substantially rectangular mining section, which, inter alia, 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 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 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 a towering the roller To enable frames to be moved in the mining theaters.
  • 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. They can be arranged on both an intermediate and on an outer frame. It is particularly advantageous if at least the region of the mining cross section between the rolls or away from the rolls is increased by folding edge cutting tools described above.
  • two rollers are arranged with their sides facing each other at an acute angle to each other, so that the axes of rotation of the two rollers include an obtuse angle.
  • the sides of the rolls facing the rock to be excavated are maximally spaced apart, while the sides of the rolls facing the propulsion means are minimally spaced from each other.
  • 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 rolls may each have at least one further edge cutting tool which projects beyond the associated roll in the direction away from the other roll.
  • 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.

  • the roller 5 When the roller 5 is in a rotational position in which the edge cutting rollers 62a are located on the front side of the roller 5, they are folded outward in the axial direction of the roller 5, so that they project beyond the frame 4. If the roller 5 is in a rotational position, in which the edge cutting rollers 62b are located within the frame 4, the edge cutting rollers 62b are folded in so that they do not interfere with the rotational movement of the roller 5 and can pass through the frame 4.
  • the unfolding of the edge cutting rollers 62a, 62b can be realized both passively, for example via springs, and in particular also actively via a separate mechanism.
  • Fig. 2 the mining device 1 is shown with extended propulsion means 3.
