Potential for Higher Ore Concentration: Often, subsurface mining targets rich ore bodies deep within the Earth. This can lead to the extraction of higher quality ores, ensuring better yield and economic returns. Lower Visual Impact: Without huge open pits or deforested areas, subsurface mining is less visually jarring.
Mining can directly and indirectly affect social and environmental systems in a range of positive and negative ways, and may result in societal benefits, but may also cause conflicts, not least in relation to land use. Mining always affects the environment, whilst remediation and mitigation efforts may effectively ameliorate some negative …
Subsurface mining increases the risk of skin diseases, lung cancer, and respiratory diseases. This polluted exposure level is higher in mountainy areas as mountaintop removal occurs. So, the risk of infections is more elevated in residential or rocky areas. Apart from humans, subsurface mines harm wildlife.

Advantages & Disadvantages of Mining. Mining is quite important to extract large amounts of precious metals and other natural resources out of the ground. However, mining also implies many serious problems. All pros and cons of mining are examined in the following.
Open pit mining method is one of the surface mining methods that has a traditional cone-shaped excavation and is usually employed to exploit a near-surface, nonselective and low-grade zones deposits. It often results in high productivity and requires large capital investments, low operating costs, and good safety conditions. The main …
Significant advantages of deep-sea mining are that in the depths there are deposits of minerals such as copper, iron, gravel, sand, diamonds, platinum, titanium, while in hydrothermal deposits we can find gold, lead, copper, zinc, etc. and this method is not dangerous to the environment compared to terrestrial methods. On the other hand, this …
In situ leaching (ISL), solution mining, or in situ recovery (ISR) involves dissolving uranium in the ground and pumping the solution to the surface where the minerals can be recovered.
