Definitions
- 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.
- 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.
- 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.
- 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 °.
- 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.
