Ramp 

(in Russian, duchka, from Polish ducza, pit), a slope built of rock in a worked-out area of an underground coal mine. The ramp is used to bring the mineral down from overlying formations, to transport fill and reinforcement materials, and to provide communications between levels. During the working of the ore deposits, the short raises drilled upward from the haulage drift or crosscut to yield the ore broken out in the mining area are called ramps.
