Definitions

  • the invention relates to a method for opening stone or rock with a chisel, in particular for producing a drillhole in rock for light to medium rock formations, and claims the priority of the German patent application 101 01 708.1, to the content of which reference is made.
  • Drilling with MUD motors is complicated in operational terms and expensive so that, as compared with drilling in loose stone formations, which is possible without the use of MUD motors, a cost factor of 5 to 10 arises.
  • controllable, asymmetric hard rock drill heads with what are known as double taper drilling rod assemblies, developed by the FlowTex company, have been used.
  • the vertically asymmetrical wing cutters of the drill heads used in this case were moved, under control, in such a way that the longer front cutter works into the rock in the desired direction as a result of short left/right pivoting movements.
  • the drillhole diameter is then machined out by means of a pilot cutter and a reamer.
  • the pilot cutter represents the longer front cutter and the reamer represents the shorter front cutter.
  • This method also entails high costs, since the required double taper drill rod assemblies are expensive.
  • the drilling device has a poor efficiency, so that only short drilling distances can be implemented with the expenditure of a great deal of time.
  • pilot cutting in order to change direction is complicated, and the wear on the pilot cutter is high.
  • the pilot cutter needs to be changed after every drilling operation.
  • the invention is, then, based on the object of providing a method for drilling stone or rock with which cost-effective and high-performance stone or rock drilling is possible.
  • the method according to the invention is based on the idea, with the aid of an asymmetric rock drill head with preferably integrated, asymmetrically arranged jet nozzles and a drilling device which can be driven forward with percussion and roration, to use a combination of rotation and impact in such a way that, by means of—preferably high-frequency—percussive pulses, pieces of stone are broken out from a specific circular section of the workface and, after a certain preferably short—period of time or a certain—preferably low—penetration depth of the asymmetric chisel, the asymmetric chisel is rotated through a specific angle, in order to move the chisel head into a new circular section of the workface and then, with the aid of the percussive pulses, to break pieces of stone out of the new angular range.
  • the asymmetry can also be implemented by means of a specific (for example geometric) nozzle arrangement or jet alignment, without the tool as such being asymmetric.
  • This procedure permits surprisingly smooth drilling advance in rock or stone with a simple rod assembly drilling device and an additional percussion drive, using a simple asymmetric drill head and, in the process, by varying the drill parameters, such as the residence time in a specific angular section, and therefore nonuniform distribution of the forward drive force onto the workface, directional drilling.
  • the device according to the invention makes it possible to avoid a wedging effect and the associated undesired distribution of the introduction of force away from the tip of the drill head.
  • the tip of the drill head can be designed to be movable, such that the entire percussive pulse is introduced into the tip of the drill head without energy being used to accelerate the rest of the drill head.
  • the percussion unit is preferably operated at a high percussive frequency—particularly preferably at more than 1000 impacts/min.
  • a variable thrust force is preferably applied to the drill head via a rod assembly.
  • the steps of impacting and of rotation can be carried out with a cyclic change.
  • the angle ⁇ can be 0° or 360° for steering, while it is otherwise preferably 0° C. and 90°.
  • Asymmetric drill heads have proven to be particularly advantageous for use in accordance with the method of the invention.
  • drilling media for cooling or cutting or removing the debris can be arranged via nozzles arranged asymmetrically in the drill head or chisel.
  • FIG. 1 shows an illustration of the workface with the drill head located in it in three drilling steps
  • FIG. 2 shows a detailed view of the drill head from FIG. 1.
  • the drilling device 1 has a percussion unit 2 , an asymmetric drill head 4 and a connection for a rod assembly 6 . Via the rod assembly 6 , both a torque and a variable axial pressure can be transmitted to the drilling device 1 .
  • the drilling device 1 with the drill head 4 is in the workface 8 .
  • the chisel point 10 of the drill head 4 is mounted such that it can move, so that the complete percussive pulse from the percussion unit 2 is transmitted to the chisel point.
  • a channel 12 for a drilling medium emerges in the front region of the chisel point 10 .
  • the axis of the chisel point 10 is at an angle ⁇ with respect to the axis of the drilling unit.
