ABSTRACT:
A flexible track (10) is held captive in an armoured face conveyor and comprises a plurality of blocks (14) arranged in longitudinally spaced relation with a pair of links (15) at opposed transverse sides of each adjacent two blocks interconnecting said blocks and forming apertures (18) between adjacent blocks. The blocks (14) have side projections (16) and the links (15) have corresponding apertures which are of slightly greater dimensions longitudinally to permit a small amount of longitudinal movement (end-float) of each block (14) relative to its two pairs of links (15). Each block has a vertical aperture (22) through its body, the apertures (22, 18) in the blocks and between the end faces (20, 21) of adjacent blocks being adapted to receive a tooth (25) of a toothed wheel (26) mounted on a machine movable along the conveyor. The aperture (22) in the block (14) has end faces (23, 24) and the profile of said end faces (23, 24) and of the end faces (20, 21) of the block where the teeth of the driving wheel engage an aperture (18) are of involute form and mirror image reversible. The armoured face conveyor is formed of a longitudinal series of line pans (30) connected end to end and having a furnishing which includes a longitudinal channel to guide and locate the mining machine relative to the armoured face conveyor. The channel holds the flexible track (10) captive for engagement by the drive sprocket wheel (26).
