What is subsurface mining? - Quora

Subsurface mining is the extraction of minerals and ores from underground. Subsurface mining is the removal of deposits from the earth by drilling underneath layers of rock and dirt. These deposits are difficult to reach from the surface and requi...

Subsurface storage : Geosolutions Leeds

Utilisation of subsurface resources for mining, carbon storage and hydrofracturing has the potential to induce earthquakes. Regulators use a “traffic light” system to manage this risk. However, existing methods used to characterise earthquakes do not account for the possible range of magnitudes, meaning that there will be cases where operations are incorrectly permitted to continue (or are ...

31/03/2020  The Tritium will then fall on the earth in the form of rain giving us the natural form of the radioactive chemical. Artificially – Tritium is achieved by bombarding hydrogen with neutrons in an accelerator or a nuclear reactor. So, unless we have a module to act as a reactor, or scoop it from a star, it cannot be mined (although Frontier stated so) Just thought you and Frontier should know ...

31/03/2020  I still go one of those subsurface missiles equipped because my mining Python had hardpoints to spare. So I'd be cool with Tritium being an asset that can only be acquired by subsurface mining -or just buying it as they mentioned, but I'd imagine it wouldn't come cheap. Eh, whatever, we'll probably be talking a lot more about this come thursday night.

Another way of the transfer of mining waste into floodplain was a "radioactive" flood in 1981, which washed away a settling pond in the mining area. Finding the hotspots of contamination by uranium and other heavy metals in floodplain was a challenge for us. The first step in the hotspot imaging was examination of a historical low-resolution map based on aerial gamma spectrometry covering the ...

Environmental Risks of Mining

When crushed, these rocks expose radioactive elements, asbestos-like minerals, and metallic dust. During separation, residual rock slurries, which are mixtures of pulverized rock and liquid, are produced as tailings, toxic and radioactive elements from these liquids can leak into bedrock if not properly contained.

Uranium: How is it Mined?

Open pit mining, also known as strip mining, is the removal of surficial soils and uneconomic rock to get at the ore below. Ore grades are normally less than 0.5%. This is type of mining is only possible if the uranium ore is near the surface (normally less than 400 ft). The Jackpile Mine on Laguna Pueblo was once the world's largest open pit uranium mine.
