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.
