FIELD: mining engineering.
SUBSTANCE: machine is located adjacent to a face conveyor for transporting the material, and comprises a chassis, a boom pivotally connected to the chassis, a blade drum for engagement with stope face, while knife drum is mounted for rotation on the boom, and the crusher rock fractures used to trap material on the face conveyor. In this case, the chassis includes a first end and a second end, the chassis being movable in at least a first direction that is substantially parallel to the stope face. The crusher of rock fractures includes an elongated crushing arm having a first end and a second end, the first end being pivotally connected to the chassis about the axis of the lever. The crusher of the rock fractures also includes a number of teeth for crushing the mined material.
EFFECT: development of longwall in a compact manner, with a compact crusher.
