Abstract
A mineral mining installation employs a scraper-chain conveyor with a guide at the mineral-face side supporting a main machine, such as a plough, driven back-and-forth along a mineral face by a chain disposed at the mineral-face side of the conveyor. A further chain drive is arranged at the opposite side of the conveyor and is drivably coupled to an arm projecting over the conveyor and connecting with a further plough body. The further plough body is either supported together with the arm on further guides so that it can be driven back and forth along the face above the main machine or else the further plough body is supported directly on the main machine with its arm guided at the opposite side of the conveyor. Releasable coupling devices enable the further plough body to be connected to the main machine.
