    • A mining machine gearcase comprises a generally rectangular casing (10) having therein intermediate the ends thereof first and second co-axial and mutually-spaced transverse horizontal shafts projecting through opposite sides of the casing and adapted rotatably to be driven by way of transmissions individual thereto from an electric motor and an hydraulic motor, respectively, both outside of the casing. The electric motor is positioned to one end of the casing (10) and the hydraulic motor to one side of the casing and between said one end and said second shaft. Rotation of the second shaft is adapted to be utilised for driving means for hauling the mining machine along a longwall face. Rotation of the first shaft (11) is adapted to be utilised to actuate, through a gear train (26) at the other side of the casing (10), a cutter drum at (13) external to the other end of the casing (10), and also to actuate, through a gear transmission (27-30 and 31) having an interposed clutch (44) and disposed within the casing between the first shaft (11) and said other end of the casing (10) and the first stage of which is a gear wheel (27) fast with and centred on the first shaft (11) intermediate its length, means (16) also external to said other end of the casing (10) for breaking up large lumps of coal which have dropped during a cutting operation, the clutch (44) being operable from outside of the casing. A longwall coal-mining machine comprises a gearcase (10) as defined above at each of its opposite ends each said gearcase (10) carrying two ranging arms (12) and (15) respectively mounting a cutter drum at (13) and a lump breaker (16), and also carrying a haulage drive means (50, 51, 52).
