A mineral mining installation intended for mining thick seams is composed of a series of units arranged alongside the mineral face and interconnected via a shifting system employing hydraulic rams operable to shift individual units. Each unit is a two story construction with a rigid underframe with roof and floor parts interconnected by pillars or walls to provide a winning chamber accessible to the face and an access chamber remote from the face and capable of housing vehicles and other equipment. On top of each underframe, to complete the unit, is a top frame composed of telescopic props resting on the roof part of the underframe and supporting a roof girder. At least one winning machine and conveyor is arranged within the forward regions of the frames of the units, and usually in the winning chambers; and the machine serves to hew mineral from the face.
