Abstract

The paper summarizes the applied experience, the technical solutions to limit the adverse effects of slope angle in the mechanized longwall mining at underground mines in the world. The paper proposes some solutions for enlarging the application field of the fully mechanized longwall mining technology according to seam dip angle at underground coal mines belonging to Vinacomin. In the article exploitation methods of coal seams of medium to thick thickness with dip angle above 20° designed for mechanized longwall were presented.
