Abstract

A drive and transfer station for an underground mining installation employs a frame with spaced apart walls over which material is transferred between scraper-chain conveyors one arranged along a long wall mineral face working and the other arranged along an access roadway. The scraper-chain assembly of the face conveyor is driven by drive assemblies on opposite sides of the frame which drive a rotatable chain drum. At least one of the drive assemblies has a coupling in a gear box with a shaft which can be displaced axially with an adjusting device to drivably connect with the drum or to be released from the drum.
