Abstract
Device for the drive of traction chains for the movement of tools for mining operations, characterized in that it is constituted by several drive motors, preferably hydraulic, distributed along the length of the pit, preferably at distances of about fifty meters, which is they have, on the front side of the coal or debris, on the conveyor, so that their drive sprockets directly grip and drive the chains of tools driven along the coal front and that is equipped with tools.
