Open pit or underground methods separately are not practicable for the extraction of this kind of deposits; therefore, a combined mining of open pit with one of underground methods is used.
· There are only 2 paths to extracting bitumen from the oil sands: by injecting steam deep underground and pumping the oil to surface (thermal insitu), or by mining the ore and physically separating the bitumen from the sand in a processing plant. Suncor Energy has been mining the oil s
Underground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente, in Chile, is the world's largest underground copper mine. Open pit mining is employed when the orebodies are extensive, low in grade, and relatively near the surface, where they can be quarried after removal of overburden.
Although underground mining is a less environmentallydestructive means of gaining access to an ore deposit, it is often more costly and entails greater safety risks than strip mining, including openpit mining. While most largescale mining projects involve openpit mining, many large underground mines are in operation around the world. ...

· Open pit mining is one of mankind's greatest achievements in the ongoing search for precious ores such as copper, silver, iron, and gold. It describes the process of systematically excavating land and digging out the rocks and minerals in search of metallic ores and removing them via borrow or open pit.
Underground mining not only produces gold, copper silver but also precious gems like diamonds rubies. The advantages of underground mining: • There are no damages to the surface environment or mine area. • The ground does not require blasting with explosives. • There is a higher production volume.
Olympic Dam (copper, uranium, gold and silver, North of Adelaide, South Australia) Renison Bell (tin, on the west coast of Tasmania) What to expect from both Open Pit and Underground mining. With both open pit and underground mining, the work can be hard and the hours long, and you can be rostered on for many days at a time.
