Abstract
This report summarizes the principles of safely working steep coal seams using longwall mining methods. The report presents the state of the art and identifies the problems that result from seam inclination. Details are given on foreign longwall faces achieving good records of safety and productivity when mining on 30 deg. to 50 deg. Inclined seams. Recommendations for further research are suggested.
