    • A longwall coal-mining machine has a gearcase at each of its ends, each gearcase carrying two ranging arms respectively mounting a cutter drum and a lump breaker, and also carrying a haulage drive. Each gearcase comprises a casing having therein first and second co-axial and mutually-spaced transverse horizontal shafts projecting through opposite sides of the casing driven by individual transmissions located in the gearcase and from an electric motor and a hydraulic motor, respectively, both outside the casing. Rotation of the second shaft drives the mining machine along a longwall face. Rotation of the first shaft actuates a cutter drum through a gear train and also actuates a lump breaker through a gear transmission.

    • A shearer-type mineral winning machine has three-phase a.c. motors on its main body for driving cutting drums and for propelling the machine along a mineral face. The frequency of the a.c. power supplied to the motor which serves to move the machine is varied and controlled in dependence on the operation of the cutting drums. Electronic control means for monitoring the performance of the cutting drums and for controlling the frequency of the a.c. power supplied to the machine drive motor are located in a control station in a protected position in a gallery remote from the machine and power is supplied to the machine via cables and/or bus bars.
