Mechanical coal wall miner moved along the excavation with the aid of a string, such as a fire chain, both ends of which are fixed to the miner, and the string extends along the excavation and is wound at the ends of the excavation on drive wheels, and the mechanical miner has skids fitted to the miner at the joints on the axis parallel to the sliding surface of the conveyor and simultaneously perpendicular to the moving direction of the miner, in particular, the skid (1) has an extension (2) located along the body (3) of the skid (1) and also crosswise to the body (3) and reaching the chain canal (12) of the lock (13), and the extension (2) has at the end and extended cross-section (4) with a flow opening (5), whereby the opening (5) is parallel to the sliding plane (6) of the skid (1), and in the opening (5) there is a rotational grip (7) of the pulling chain (8), whereby the chain canal (12) is also the guide for the miner.<IMAGE>
