Cost Models of Theoretical Mining Operations

This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. Rock characteristics for both ore and waste are typical of those of granite or porphyritic material. Operating conditions, wage scales, and unit prices are typical for western U.S. mining operations. All costs listed are in 2012 US$.

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 Cut and Underground Mining

What are the differences between open-cut and underground mining? Open Cut Mining. There are many differences between open cut and underground mining. When minerals and deposits are found close to the surface and spread across a large distance, the best way to mine is to use the open cut mining method.

What is a disadvantage for open pit mining

Open pit mining has been done since prehistoric times. At first, a quarry was probably opened to recover stone used in building. In this light, no one person or group can claim the introduction or invention of open pit mining. Certainly the scale on which we conduct open pit mining today doesn't begin to compare with these ancient methods.
