Abstract: A longwall coal cutter and loader for longwall mining operations has a machine body drivable along a longwall conveyor in the longitudinal direction of the longwall surface, and at least two cutting rollers complementing or overlapping each other with their cutting sections. In order to improve the transverse transport of the mined material onto the longwall conveyor, to optimize the arrangement of the cutting tools on the cutting rollers in view of the cutting action, a horizontal roller is provided for cutting free the roof. The horizontal roller has a rotary axle extending parallel with the roof and cooperates with a vertical roller for cutting free the sill, the vertical roller having a rotary axle extending perpendicular to the sill. The horizontal roller is arranged above the vertical roller and leads the vertical roller in the direction of travel in the mining operation.
