Study on some solutions for enlarging the application scope of the fully mechanized longwall coal mining technology according to seam dip angle at underground coal mines in Quang Ninh coalfield

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