When this occurs, the exhausted mines are sometimes converted to landfills for disposal of solid .

Advantages and disadvantages of open pit mining ~ .

Advantages and disadvantages of open pit mining Open pit mining is profitable when the deposit is not very deep or when the terrain is sandy or delicate, so that underground mining is not possible. Labor costs are lower, both in excavation and transportation, and allow the use of large machinery . .Open-Pit Mining Definition | Anglo AmericanOpen-pit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels. This surface mining technique is used when mineral or ore deposits are found relatively close to the surface of the earth.
