Embodiment Construction

[0060] figure 1 It is disclosed that the drilling pattern 1 and mining plan 2 can be designed by a mining engineer 3 in an office 4 . The drilling pattern 1 is transmitted to a rock drilling machine 5 comprising a movable carrier 6 and one or more drilling units 7 . In the drill and blast method, the mine tunnel 8 is produced in several successive rounds 8a-8d. The rock drill 5 is positioned at the face 9 of the next pass and is related to the coordinate system of the mine. The rock drill drills the blasthole according to the designed drilling pattern 1, wherein after the blasting round 8a, the broken rock material is removed. Then, a new face is formed and the rock drill 5 is again positioned and navigated for the next drilling pass 8b. A number of successive rounds 8a-8d together form a mining tunnel line 10, which in figure 1 is shown in a highly simplified manner. The mining tunnel line 10 may be provided with stake numbers 11 indicating distances along the mining tun...

Abstract

An apparatus, a rock drill, a method and a computer program for performing navigation for a rock drill in a mine tunnel. The rock drill (5) is positioned at the working face (9) of the round (8) and is navigated before starting drilling. The navigation is performed without a predetermined tunnel line (10). The realized tunnel line is formed by combining navigation data of a plurality of rounds. And the length and the direction of the next to-be-drilled round can be adjusted as required.

Description

technical field [0001] The invention relates to a device for navigating a rock drilling machine in a mining tunnel. [0002] The invention also relates to a rock drilling rig implementing the device, and also to a method and a computer program for navigating a rock drilling rig in a mining tunnel advancing in successive rounds. [0003] The field of the invention is defined more particularly in the preambles of the independent claims. Background technique [0004] In mines, underground tunnels are excavated using the drill and blast method, in which rock material is removed in several successive rounds. A mining tunnel can be a production tunnel or a connection tunnel. Today, mining tunnels are advanced according to predetermined tunnel lines designed in the office. Then, for each round, the rock drill is positioned and navigated so as to achieve the planned tunnel. Usually, navigation is based on simple markings made on rock faces. The current way of working has some s...
