Longwall mining shearers equipped with drum-type mechanisms have become widely applied equipment in underground coal exploitation. The constructive evolution, quality, reliability, and functional performance of these machines, influenced by technological advancements in materials and manufacturing, is nonetheless overshadowed by their adaptability to various geological and mining conditions, particularly concerning the parameters of the cutting mechanism. A judicious correlation of geometric, dimensional, kinematic, and functional parameters with the characteristics of the coal seam provides a vast field for research. For this reason, we have approached this type of equipment, with special emphasis on the working components, in a study where computer-based methods can prove their utility.
