A mining machine includes a chassis, a boom, a cutting head, and a shield supported for movement relative to the chassis. The chassis includes a first end and a second end, and defines a longitudinal axis extending between the first end and the second end. The boom includes a first end and a second end, and the boom is supported for movement relative to the chassis. The boom translates in a first direction and is pivotable relative to the chassis between first and second positions. The cutting head is coupled to the second end of the boom and is supported for rotation relative to the boom. The cutting head is rotatable about a cutting head axis. The shield is supported for movement relative to the chassis and positioned proximate the cutting head. In some embodiments, the shield is coupled to a sumping frame supported for movement relative to the chassis. |
