A shearer-loader type mining machine 1 has shearer discs 3 rotatably mounted on carrier arms 4, the disc end face 12 which is near the working face being ventilated by way of a duct 14. The two carrier arms 4 each have a liquid pump 17. The pumps 17 are flanged onto the carrier arm side wall distal from the working face and are connected to the carrier arm drive by way of a clutch 20. IMAGE
