2020-3-12 Longwall mining. Using specialized machines, longwall mining is an underground mining method that cuts out panels of the coal, which are then sheared down and brought to the surface. This method is highly mechanized, and is therefore a very safe type of mining. It is a highly productive method as well, with a very low cost per ton as compared to some other methods. However, longwall mining
