ARRANGEMENT FOR ASSIGNING AND DRILLING BORE HOLES

摘要

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.

主权项

1. An apparatus for assigning positions of drill holes for a round to be drilled by a rock drilling rig, the apparatus comprising:
at least one data processing device arranged to receive data on drill holes to be drilled for the round; and an actual position and direction data on a tool connected to a rock drilling unit of the rock drilling rig; a sensing arrangement 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 the forthcoming position of the drill hole bottom before drilling the new drill hole, the determining being based on the current location and direction of the tool and on the predetermined length of the new drill hole; and an input device to indicate the determined position of the forthcoming drill hole bottom of the new drill hole in relation to the realized drill hole bottoms on the bottom of the round.
