The Two Methods Of Surface Mining And Underground

The two methods used for underground mining is cut and fill and room and pillar. Cut and fill is when the material extracted from underground is then used to fill another space. Room and pillar is when the ore is extracted in a horizontal line. There are two phases to extracting a mineral using the room and pillar method. Surface mining is when ...

The Actual Difference Between Surface and Underground

Surface mining can be accomplished by the following main methods: Open-pit Mining: Removing ore to leave a crater. Quarrying: An open-pit mine for construction materials. Strip Mining: Ore is removed in parallel strips. Mountaintop Removal: Top of a mountain is blasted to remove deep ore. Dredging: Ore is removed from a river bottom. The main methods of underground mining

mining - mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground
