A method and equipment for displaying holes to be drilled when drilling holes into rock with a rock-drilling rig having control equipment and a display belonging thereto and measuring means for defining the direction and position of a drill rod, by using a pre-designed drilling plan defined in a three-dimensional coordinate system, in which a starting point (to) and end point (to) is defined for each hole to be drilled. A base plane running through the end point (to) of the hole and parallel to the projection plane is defined for each hole (to), and a projection of the intersection of a hole or its extension created when drilling in accordance with the current location of the drill rod and the defined base plane is displayed with a graphical location symbol on the projection plane.

Method and equipment for displaying drill holes and method for directing drill rod when holes are drilled into rock

A method and a computer program for controlling a drilling cycle in a rock drilling apparatus, and a rock drilling apparatus. In accordance with the invention, each drilling unit in the rock drilling apparatus is monitored during a drilling period, and a drilling sequence of a control unit in the rock drilling apparatus is updated at predetermined intervals during the drilling period. The total time of the drilling and the time elapsed for different operations can be registered. In addition, according to an embodiment, the drilling sequence is changed during updating, if changes occur in the drilling conditions during the drilling period.

Method for controlling a drilling sequence, a rock drilling apparatus and a computer programme to form a drilling sequence

A method of controlling rock drilling wherein the cut length changes from a predetermined cut length, the drilling length is changed by transferring the position of the pattern in the longitudinal direction of the tunnel so that the positions of the end points of the holes remain essentially the same with respect to one another, and a collaring surface is crosswise of the tunnel and different from the actual rock surface.
