Abstract

A method for mining and a planer installation for the mining of coal, with a coal planer that can be moved by a planer chain that can be driven via a drive chain wheel of a drive station for the planer chain and that is deflected at a deflection chain wheel of a driveless deflection station. The coal planer is moved back and forth reversibly between the drive station and the deflection station by the planer chain to avoid the occurrence of sag and to minimize the necessary size of an auxiliary drift to be opened. The deflection chain wheel is mounted on a slide that can be displaced in the direction of movement of the coal planer by a tension device.
