In order to address the issue of high temperatures and thermal damages in deep mines, the factors causing downhole heat damage at high temperatures were analyzed, the mine ventilation system was optimized and rebuilt, and a cooling system was established. The proposed cooling system uses mine water as the cooling source, and its features are based on the analysis of traditional cooling systems.
My preference is to mine Painite in a double painite hotspot. Some people prefer deep core mining. Deep core is more engaging and active, and arguably more fun (making rocks go boom), while regular mining is more laid back. Both are highly profitable, there are …

Mining sites. Deep sea mining is a relatively new mineral retrieval process undergoing research which takes place on the ocean floor.Ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at about 3,000 – 6,500 meters below the ocean's surface. The vents create sulfide deposits, which contain precious metals such as silver, gold ...

It also requires more equipment and greater driving skills. However, RC drilling results in greater sample accuracy, making it a more popular form of mining exploration. It is the most common drilling technique used for mining exploration, particularly in South America and Australia.
Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.

mining - mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the ...
