Abstract: The directions of improvement of constructions of the crowns of roadheaders of selective action and other mining machines. Suggested usage biconical, conical disk tools and sites of their attachment to the triangular prisms on the crowns of roadheaders and shearers-bladed screws for the destruction of structurally inhomogeneous working faces. Presented solution to the problem of combining the processes of destruction, crushing and loading rock effectors boom-type when working roadheaders selective action. Recommended agreed reverse modes two radial crowns with a disc tool mounted on triangular prisms for the extension of front loading in the cut off space of the mine workings. The process of formation of loads on the disc tool in the destruction of rocks. Shows the calculated dependences of the transverse efforts at the effector with two kinematically connected radial reversible crowns for eight standard fixed stages of rotation of the crowns with the disc tools in the destruction.

Key words: roadheader effector crown triangular prism disc tool reverse displacement rock face contact strength effort moment
