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...
