FIELD: mining engineering.
SUBSTANCE: executive organ of the mountain tunnelling machine comprises at least one cutting disc that is rotatably supported on the lever and located at an acute angle to the face. The lever is rotatably mounted. The axis of rotation of the lever is able to move.
EFFECT: ensuring the uniform removal of rock layers, the ability to process a large area of the face with a smaller number of cutting tools and eliminate the dependence of the diameter of the discs on the dimensions of the workings.
