W: Mechanika 2017 : proceedings of the 22nd International Scientific Conference. Kaunas : Kaunas University of Technology, s. 27-31. Development and Analysis of the Kinematics of the Working Unit of a Mobile Drilling Rig Self-propelled drilling rigs are widely used in the underground mining. Their main task is drill- ing holes in the rocks, where further the explosives charges are placed. Important feature of this type of the machine is ability of performing the drill holes according to the blasting param- eters defined in the documentation. Precision of the holes distribution and their angular devia- tion is crucial for the rocks fragmentation. The paper presents the results of the kinematic anal- ysis of the working unit of a drilling rig designed for KGHM Polska Miedź S.A. The authors determined design and construction aspects influencing on accuracy of the drilling boom posi- tioning. The working field of the described system was equal 45m 2 .
