dumb screen
A chute in which there are no meshes or bars for separating the coal, and down which the run-of-mine coal passes from the tubs direct to the railway wagon. It is used in small mines where the coal is sold as loaded underground or at mines where the coal is conveyed by wagon to a central coal-preparation plant.
