ABSTRACT:
Layers of overburden are progressively removed from one inclined side of a cut by a rotating cutter and deposited on the other side of the cut in substantially the same geological sequence by traversing the cutter along an arm sloping along the inclined side, conveying the removed overburden by the arm to the bottom of the cut, and depositing the overburden by an adjustable endless belt on the opposite sloping side. The arm is moved along the sloping side by self-propelled transport units at the top and bottom of that sloping side.
