Abstract

Apparatuses, methods, computer programs and systems for enhancing drilling accuracy for a mobile underground drilling rig are disclosed. With the disclosed inertial measurement unit (IMU) (11), a vertical orientation error caused by a drilling boom (3) and/or a feed rail (5) bending may be directly measured and corrected, for example. A position error caused by the drilling boom 3 bending may be corrected or at least reduced by using the IMU 11 data in compensation data/models. Such combined/new compensation data does not depend on drilling direction, such as face drilling, ramp drilling, and cross-cut drilling. Furthermore, the IMU (11) may be used to measure a change in a feed angle caused by contact forces between the feed rail (5) and rock, thereby further improving overall mining accuracy.
