Fault-holing machine for underground winning operations, in particular plough operations

摘要

The invention relates to a fault-holing machine for use in underground winning operations in which the working is carried out by means of a winning apparatus, in particular a plough apparatus, while using a machine guide for a winning machine (plough), which machine guide is arranged on the working-face side on a shiftable conveyor. The fault-holing machine is a shearer which runs with its machine body over a conveyor and has a vertically pivotable shearing arm with a driven shearing drum or the like. According to the invention, the shearing arm (23) with the shearing drum (24) is mounted on the machine body (17) in a transversely movable manner in the direction of the working face (11), the shearing drum lying behind the face-side limit (15') of the machine guide (15) in the position fully retracted from the working face. Here, the breadth of the fault-holing machine is located on the working-face side in the shadow of the machine or plough guide (15), as a result of which unhindered mobility of the machine in the face cavity is guaranteed. <IMAGE>
