Surface Mining Methods HomeHighwall mining is also safer than other types of mining, and when, it occurs at the surface, it often produces the same amount of output as mining underground does. Smaller blocks of coal can be accessed with high wall mining, and operations can take place around structures or geological impediments that may otherwise impinge upon the production of coal.SURFACE MINING METHODS REFERENCE: BULLIVANT, DA.
