Abstract
A longwall mineral mining installation has a longwall conveyor, a plough guide attached to the face-side of the conveyor, and a main plough movable to and fro along the guide. A respective stable-hole plough is movable to and fro along portions of the plough guide adjacent to each end of the conveyor. Each stable-hole plough is driven by means of a respective endless drive chain which passes round two end sprockets. One end sprocket of each stable-hole plough is positioned at the face-side of the conveyor part way therealong. The other end sprocket of each stable-hole plough is positioned at the adjacent end of the conveyor on the goaf-side thereof. Each drive chain passes round a direction-changing unit positioned at the adjacent end of the conveyor.
