Abstract
Self-propelled drilling rigs are widely used in the underground mining. Their main task is to drill holes in the rocks where explosive charges are to be placed. An important feature of this type of machine is its ability to drill holes according to the blasting parameters defined in the documentation. Precision regarding the hole distribution and angular deviation is crucial for fragmentation of the rocks. This paper presents the results of a kinematic analysis of the working unit of a drilling rig designed for KGHM Polska Miedź S.A. The authors determined the design and construction aspects influencing the accuracy of the drilling boom positioning. The working field of the described system was equal to 45 m?.
