Popis:	Due to the import of cheap primary energy resources, the German domestic coal mining industry is forced to rationalize the organization and to reduce the production cost. Though the economical situation is stil severe, the new R & Ds and the improvement of practical technologies have been continued in a limited budget range. Many of them are remarkable technolgies to overcome the severe underground mining conditions and to increase productivity and to improve safety performance.This report summarizes the recent R & Ds and practical technologies developed in German coal mining industries. It includes technologies on coal cutting, roadway drivage, material and man transportation, roadway maintenance, safety devices, utilization of mined-out space and safety management. The tndency of these technologies is described in conclusion.
