ABSTRACT:
In a mining machine (1) designed for underground operation, for example for cutting coal seams, and being equipped with a removal conveyor means taking up the heap of debris in front of the mine face and transferring this heap of debris to a removal conveyor plant (18) arranged behind the mining machine (1), there is interpositioned, separately from the mining machine, between the mining machine (1) and the removal conveyor plant (18) a crushing aggregate (2) comprising its own travel drive and being movable on a chassis in particular being equipped it caterpillars (27). The crushing aggregate (2) comprises a receiving chute (11) provided on a frame (25), a conveyor (12) starting from this receiving chute and extending with its discharge end beyond said frame and at least one crusher roll (13) within the area between the receiving chute (11) and the discharge end (15) of the conveyor (12). At least one device for boring anchor holes and placing anchors in position is arranged on the frame (25) within the area of its front portion located adjacent the mining machine for being displaceable in advancing direction and in transverse direction thereto. On account of the crushing aggregate (2) being arranged separately from the mining machine (1), the mining machine (1) can be moved while the crushing aggregate (2) remains on one and the same place. The crushing aggregate (2) is then stepwisely moved in direction to the mining machine (1).
