Environmental impacts of coal - Global Energy Monitor

Acid mine drainage (AMD) refers to the outflow of acidic water from coal or metal mines, often abandoned ones where ore- or coal mining activities have exposed rocks containing the sulphur-bearing mineral pyrite. Pyrite reacts with air and water to form sulphuric acid and dissolved iron, and as water washes through mines, this compound forms a dilute acid, which can wash into nearby rivers and ...

Plus, the coal-mining pay is good — $80,000, sometimes up to $100,000 a year. Compare that with the pay at Wal-Mart, a fifth of that at best, and factor in that mining is a family tradition, and the choice begins to make sense. For some, there is also a thrill to descending deep below the earth’s surface and facing danger, says Blair. Some enjoy the camaraderie of being with their buddies ...

Hydraulic mining - Wikipedia

Hydraulic mining is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal.. Hydraulic mining developed from ancient Roman techniques that used water to excavate soft underground deposits.
