7. Much of the coal produced in India is obtained through which among the following types of Mining?
- Shaft mining
- Drilling
- Quarrying
- Open cast mining
Show Answer
Answer: Open cast mining
Much of the coal produced in India is obtained through Open cast mining. Open-cast mining, also known as open-pit mining, is a surface mining method commonly used for extracting coal and other minerals that are located close to the surface. It involves the removal of overburden (soil, rock, and other materials) to access the coal deposits beneath, making it a prevalent method for coal extraction in India.
8. In which type of mining, deep underground tunnels are made to obtain minerals?
- Shaft mining
- Drilling
- Open cast mining
- Quarrying
Show Answer
Answer: Shaft mining
Deep underground tunnels are made to obtain minerals in the mining method known as Shaft mining. In shaft mining, vertical or inclined shafts are dug into the Earth to access valuable minerals or ores that are located deep underground. Miners and materials are transported through these shafts, and it is a common method for accessing deep-seated resources.
9. In what type of mining, the minerals are obtained from under the ground by means of making large dug out hollows?
- Shaft mining
- Drilling
- Open cast mining
- Quarrying
Show Answer
Answer: Open cast mining
The type of mining where minerals are obtained from under the ground by means of making large dug out hollows is called Open-cast mining. In open-cast mining, large excavations or open pits are created to access and extract valuable minerals or ores that are located beneath the Earth’s surface. This method involves the removal of overburden (soil, rock, and other materials) to reach the ore deposits and is often used for resources located relatively close to the surface.
10. In what type of mining, minerals are just dug out of the rocks?
- Shaft mining
- Drilling
- Open Cast mining
- Quarrying
Show Answer
Answer: Quarrying
Minerals are just dug out of the rocks in the mining method known as Quarrying. In quarrying, minerals or construction materials are extracted directly from open pits or excavations near the Earth’s surface without the need for extensive underground work or drilling. This method is commonly used for obtaining resources like stone, sand, gravel, and other non-metallic materials that are easily accessible near the surface.
