Abstract
An apparatus and method for assigning drill holes. The apparatus is arranged to determine a forthcoming position of a bottom of a new drill hole before it is drilled. The forthcoming position of the drill hole bottom is determined on the basis of the current location and direction of a tool and a planned length of the drill hole.
Claims17
An apparatus arranged to assign positions of drill holes for a round to be drilled by a rock drilling rig during a drilling process, the apparatus comprising:
- at least one data processing device arranged to receive data from a drill hole length module on drill holes to be drilled for the round and an actual position and direction data of a tool connected to a rock drilling unit of the rock drilling rig;
- a sensing arrangement arranged to determine the actual position of at least one realized drill hole bottom by detecting the position of the tool on the bottom of the round during the drilling process, wherein the processing device is arranged to determine for a new, currently active drill hole a forthcoming position of the drill hole bottom before drilling the new, currently active drill hole, the determining being based on a current location and direction of the tool and on a predetermined length of the new drill hole;
- and
- an input device arranged to indicate the determined position of a forthcoming drill hole bottom of the new, currently active drill hole based only on a drilling pattern generated during the drilling process that takes into account the current location of the realized drill hole.

A method for drilling a round, the method comprising the steps of:
- providing a rock drilling rig having at least one rock drilling unit and a tool connected to the drilling unit;
- drilling several drill holes for the round with the rock drilling rig during a drilling process;
- determining with a sensing arrangement an actual position and direction of the tool;
- and
- determining with at least one data processing device a forthcoming position of a bottom of a new drill hole before drilling the new drill hole, wherein the position of the new drill hole bottom is determined on the basis of a current location and direction of the tool and on a planned length of the new drill hole based only on a drilling pattern generated during the drilling process that takes into account the current location of the realized drill hole.
