What is the opposite of opencast mining?
The opposite of opencast mining is underground mining, where minerals are extracted beneath the earth's surface through tunnels and shafts rather than through open pits.
What do you mean by opencast mining?
Opencast mining is a surface mining technique where minerals are extracted from the earth by removing the overlaying rock or soil. This method is used when deposits are close to the surface and involves the use of heavy machinery to extract the resources. It is also known as open-pit mining.
What is the difference between opencast mining and shaft mining?
Opencast mining involves extracting minerals from an open pit, while shaft mining involves digging tunnels or shafts deep underground to access mineral deposits. Opencast mining is typically used for shallow mineral deposits, whereas shaft mining is used for deeper deposits that cannot be easily accessed from the surface.
What are two ways to mine coal?
Coal is mined by two methods: surface or 'opencast' mining or underground or 'deep' mining.The choice of mining method largely depends on the geology of the coal deposit. Underground mining currently accounts for a bigger share of world coal production than opencast; although in several important coal producing countries surface mining is more common.
Where do you use drilling method of mining?
Drilling is used in almost every type of mining to sample and determine the extent of a the deposit. Drilling is used for actual extraction of salt (by solution mining), petroleum, and natural gas.

Why opencast mining is cheaper for companies?
because opencast mining doesnt require shafts and tunnels to be built unlike other approaches such as deep mining. it is on the surface so transportation costs from underground to ground level do not exist. insurance costs for miners may be lower as there is no risk of the mine 'caving in'.

What is the main land usage at Moe Victoria?
The main use of land at Moe, Victoria, is coal mining. Much of the land surrounding the town is utilised as opencast mines of brown coal in the area.

What is the place where rock or mineral deposits are excavated from surface of land?
opencast mine
