Abstract

At the start of the research work, a total of 402 km of seam and rock drifts were being headed in West German coal mining - 151.1 km, or 37.6% of them, by machine. Mechanised heading has been growing steadily in recent years. In order to extend its range of application to more difficult conditions at great depth, it was necessary to adapt machine and process improvements achieved in the course of earlier research work in order to meet more stringent demands relating to covergence, methane drainage and temperature.
