Abstract
A coal plough for underground mining has a plough body that is guided along a plough guide. The plough body has at least one foot piece which receives a sliding skid. The sliding skid has at least one contact surface formed on its underside, which surface slides on a rail of the plough guide when the sliding skid is in its operating position. The sliding skid has first and second wear inlays on an underside which is arranged in the area of the highest load. The sliding skid can withstand high mechanical loads for a longer period of use.
