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 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 is opencast mining?
Opencast mining is a surface mining technique used to extract minerals or other resources that are located close to the surface. It involves removing the overlying layers of soil and rock to access the ore deposits underneath. This method is often used for coal, copper, and iron ore mining.
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'.
