Mineral mining installation

A conveyor is disposed beneath the cantilever track for the receipt of mined mineral, but does not bear any of the weight of the machine. The support element has utility supply conduits for use at any location along a mineral face. The installation can be used in thick seams working on the retreat principle and for seams of the order of 8 M can be provided with a rear section also having an elevated support track for supporting a machine capable of taking a substantial roof cut in the wake of the forward section.
