What technologies are used in mining?
There are some technological methods that are used in mining are:Open-cast mining : Open-cast mining is done when a mineral is located very close to the surface. In the open-cast mining, different minerals are taken out by removing the surface layer. Open-cast mining is famous for coal mining in India and many other countries.Shaft mining : The word 'shaft' refers to deep bores. In the shaft mining, deep bores are created to reach mineral deposits. This is because, these deposits lie at great depths. Petroleum and natural gas are extracted by shaft mining.
What was the advantage of using hydraulic mining when mining for gold?
Hydraulic mining blasts away the surface of the mine with highly pressurized jets of water. This allows for easy access to the minerals underneath. A negative consequence of Hydraulic mining is the damage to the surrounding environment.
What is open cast mining?
Open cast mining is mines that are dug on hilly areas. It is quick easy way of providing coal but it damages the wildlife and can be quite dangerous.
