Definitions
- the invention relates to a method for chiseling rock or rock, in particular for producing a rock hole for light to medium-sized rock formations, and claims the priority of German patent application 101 01 708.1, to which reference is made in terms of content.
- MOD motors are usually used for drilling in lighter to medium-sized rock formations. These are screw motors that work according to the Moineau principle.
- Drilling with MUD motors is technically complex and expensive, so that there is a cost factor of 5 to 10 compared to drilling in loose rock formations, which is possible without the use of MUD motors.
- controllable, asymmetrical hard rock drill heads with so-called double wedge drill rods developed by FlowTex were used.
- the height-asymmetrical wing blades of the drilling Heads were moved during steering so that the longer front cutting edge worked into the rock by short left / right swiveling movements in the desired direction.
- the diameter of the borehole is then worked out by pre-cutters and reamers by rotating the entire drill head.
- the pre-cutter represents the longer front cutting edge and the reamer the shorter front cutting edge.
- This method is also associated with high costs, since the required double wedge drill rods are expensive.
- the drilling device has a poor efficiency, so that only short drilling distances can be realized with a high expenditure of time.
- the pre-cutting to change the direction is complex and the wear of the pre-cutter is high. In practice, the pre-cutter must be changed after each drilling operation.
- the invention is based on the object of creating a method for rock or rock drilling with which inexpensive and efficient rock or rock drilling is possible.
- the method according to the invention is based on the idea of using a combination of turning and striking with the aid of an asymmetrical rock boring head with preferably integrated asymmetrically arranged jet nozzles and a beating and rotating propelling drilling device in such a way that - preferably high-frequency - impact pulse rock pieces of a certain circular section of the working face are broken out and after a certain - preferably short - time period or a certain - preferably small - penetration depth of the asymmetrical chisel, the asymmetrical chisel is rotated by a certain angle in order to move the chisel head into a new circular section of the working face move and then use the impact impulses to break rock pieces out of the new angular range.
- the asymmetry can also be realized by a specific (eg geometric) nozzle arrangement or jet alignment, without the tool as such being asymmetrical.
- This procedure allows a surprisingly quick drilling in rock or rock with a simple asymmetrical drill head to be achieved with a simple rod drilling device and an additional percussion drive and by varying the drilling parameters, such as the dwell time in a certain angular section, and thus uneven distribution of the driving force to implement directional drilling on the face.
- 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, so that the entire impact pulse is introduced into the drill head tip without energy being used to accelerate the remaining drill head.
- the impact unit is preferably operated at a high impact frequency - particularly preferably at more than 1000 impacts / min.
- a variable thrust force is preferably applied to the drill head via a linkage.
- the steps of turning and turning can take place in a clocked change.
- the angle ⁇ can be 0 ° or 360 ° for steering, while it is otherwise preferably 0 ° and 90 °.
- Asymmetric drill heads have proven to be particularly advantageous for use according to the method according to the invention.
- drilling media for cooling or cutting or discharging the cuttings can be arranged via nozzles arranged asymmetrically in the drill head or chisel.
- Fig. 1 is a representation of the working face with the drill head lying therein in three drilling steps and
- FIG. 2 shows a detailed view of the drill head of FIG. 1.
- the drilling device 1 has a striking unit 2, an asymmetrical drilling head 4 and a connection for a rod 6. Both a torque and a variable axial pressure can be transmitted to the drilling device 1 via the linkage 6.
- the drilling device 1 with the drilling head 4 is located in the working face 8.
- the chisel tip 10 of the drilling head 4 is movably mounted, so that the complete impact pulse of the striking unit 2 is transmitted to the chisel tip.
- a channel 12 for a drilling medium emerges in the front region of the chisel tip 10.
- the axis of the chisel tip 10 has an angle ⁇ with respect to the axis of the drill.
- an area of the rock is broken out of the working face 8 with the chisel tip 10 (FIG. 1).
- a variable pushing force is exerted on the drilling device via the linkage 6.
- the drilling device and thus the drilling head is rotated by an angle ⁇ in order to knock out a piece of rock from the working face in this position in a new area of the working face 8 using the impact drive 2.
- the angle for steering is 0 ° or 360 °, with the latter achieving particularly good propulsion.
