Mining
Mining for coal is something that is widely known, but did you know that diamonds, uranium, copper, and other non-renewable natural resources are also mined? There are two types of mining; surface and subsurface. Questions about the methods and types of mining, what ores are mined, and related questions should be asked in this category.

Can mining companies make or cannot make repairs to land after the mine is used?
Mining companies can and should reinstate the land after they have mined it.
Shaft mining or shaft sinking refers to the method of excavating a vertical or near-vertical tunnel from the top down, where there is initially no access to the bottom.
Mining is crucial for extracting valuable minerals and resources that are essential for various industries, including construction, technology, and energy. It provides raw materials such as metals, coal, and precious stones, which are foundational for manufacturing and economic development. Additionally, mining creates jobs and stimulates local economies, contributing to infrastructure development and community growth. However, it also poses environmental and social challenges that require careful management and sustainable practices.
Where were known coal deposits in the US in 1860?
Coal was a good source of fuel in the 1860's in the US. Large deposits were used for industry then and even today, coal mining continues in places such as West Virginia. In 1860, however, geologists had maps of where they believed that large coal deposits lay deep underground. One line of coal, for example was a continuous line stretching from the middle of Pennsylvania southward to central Alabama. Another large coal field lay beneath the cornfields of Iowa and Illinois.

Is illmenite and rutile iron ores?
Ilmenite and rutile are both titanium-bearing minerals rather than traditional iron ores. Ilmenite (FeTiO3) contains iron in addition to titanium, while rutile (TiO2) primarily consists of titanium with trace amounts of iron. Both minerals are important sources of titanium for industrial applications, but they are not primarily mined for iron.
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.
