Rotary-percussion drilling machines are commonly used for drilling hard-to-cut and abrasive rocks. Currently, in underground mining, drilling jumboswith hydraulic drilling machinesand rotary percussion drilling machines are used in chamber-and-pillar systems. The article presents results ofthework aimed at assessing the technical possibilities of creating an electric rotary-percussion drilling machinewith the parameters of currently used hydraulic drills. The biggest challenge is to obtain high impact energy and frequency as well as rotation speed and torque while limiting the weight and size of the drilling machine. The required parameters of the electric drilling machinewere the parametersof thehydraulic drilling machines used at KGHM Polska MiedźS.A.Known and applicable design solutions for electric drilling machines were analysedincluding thereported inventions in Poland and abroad. Then, three design solutions were selected and dynamic model tests were carried out, the main goal of which was to estimate the required torque, which, combined with the rotation speed, determines the power of the electric motor. As a result, thesolution was obtained, which in terms of weight and dimensions does not differ significantly from the hydraulic drilling machines, while at the same time enabling the achievement of similar operational parameters that determine the mechanical drilling speed.
