The Dangers of Deep Sea Mining

The mining industry will increasingly use this argument to promote deep-sea mining, but it''s a false comparison, as this report details. We know dangerously little about the world''s oceans. A sensible way forward would be to hit the pause button on deep-sea mining until greater scientific consensus can be reached on the full short and long-term impacts of this new industry.

Causes, Effects and Solutions for Mining

Since mining often includes the extraction of metals and other resources deep under the surface, it can lead to serious erosions. These erosions may in turn lead to a state where the eroded land is no longer suitable for human use like housing or farming since the soil is too unstable and poses too many dangers of further erosion.

Mining Technology

However, in underground mining, blast mats are not used as it is not necessary to suppress sound and rock can fly freely. As detonating explosives releases toxic gases, such as nitrogen oxide (NO), nitrogen dioxide (NO 2 ) and carbon monoxide (CO), workers must wait until gas has dissipated and the area is ventilated before resuming work or seriously risk their lives and health.

The Impact of Surface and Coal Mining on Environment

In underground mining some amount of coal is left in the caved out area. On exposure to air, coal being a carbon compound undergoes auto-oxidation and produces heat energy. If this heat is not able to dissipate fully then the coal may ignite and burn for long periods resulting in a mine fire.
