Abstract
A mine roof support or lining frame for use in mine workings with thick inclined seams has hydraulic props mounted between an inclined goaf shield and a floor sill. The floor sill is coupled with a shifting mechanism to a frame supporting a conveyor extending along a working face of the seam. Mineral from a region of the seam extending over the support passes through an opening in the shield onto a chute which takes an inclined disposition parallel to the conveyor. Material transferred to the chute discharges in the direction of transport of the conveyor.
