ABSTRACT:
A seam-mining apparatus has an excavating trough disposed ahead of a conveying trough and an endless chain passes over direction-change devices between these troughs. The excavating and/or conveying tools carried by the chain are articulated and formed with a head portion, an intermediate portion and an end portion. The intermediate portion is connected to the head portion and end portion by pin joints whose axes are perpendicular to the chain and to the bottom of the conveyor trough, and hinge joints whose axes are orthogonal to the axes of the pin joints. The guides for the head and end portions of the troughs extend into the direction-change regions.
