Abstract: A conveyor system for conveying coal out of a coal mine includes a first conveyor and a second conveyor coaxially aligned with the first conveyor. The first conveyor includes a frame having longitudinal side rails and a conveyor tunnel structure having a coal discharge outlet opening located over the side rails at the downstream end thereof. The first conveyor further includes an endless belt structure trained about a head pulley located in the conveyor tunnel and about a tail pulley located proximate the upstream end of the first conveyor frame. A first conveyor drive sprocket is mounted to the head pulley. The second conveyor includes a tail pulley at its downstream end mounted to the conveyor frame of the first conveyor beneath the coal discharge outlet opening of the conveyor tunnel structure, a head pulley, and an endless belt structure trained about the head pulley and tail pulley. A second conveyor driven sprocket is mounted to the second conveyor tail pulley, and a drive belt or chain is trained about the first conveyor drive sprocket and second conveyor driven sprocket. A second conveyor drive sprocket is mounted to the second conveyor head pulley, a drive motor having a drive sprocket is positioned near the downstream end of the second conveyor, and a drive belt or chain is trained about the second drive sprocket and drive sprocket of the drive motor.
