Longwall Top-Coal Caving: A productive and efficient alternative. Longwall mining is one of the most productive ways to produce coal, but longwall mines have trouble efficiently mining seams higher than 6 m (19.6 ft). Longwall Top-Coal Caving can more than double the resource recovery rate of normal longwall equipment working in high seams.
