what is the difference between mining and quarrying

Apr 04, 2009Best Answer I think quarrying is usually done on the surface of the earth instead of under it. Blocks of material are taken whole from the pit, like stone, marble, etc. Care is taken to not destroy the blocks when they are cut, since it would lower or even ruin their value to builders and sculptors.

Basics of an open pit mine mine-engineer

In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal. In a hard rock mine, the bottom of the pit would be the lowest level (elevation) that mining would be conducted on the ore being mined.

Environmental Risks of Mining Massachusetts Institute of

Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.
