Adit Mining edit
An adit is an opening or passage. Adit Mining is done in hilly districts where a mineral seam is exposed on a hillside. Added By KoMal KhAn --116.71.94.11 (talk) 11:32, 10 April 2009 (UTC)
An Adit is driven from the surface very slightly to the rise, just steeply enough to drain freely. Usually it will follow an ore vein so it will not run in a straight line. It is used to extract and access the ore. If a drivage is primarily for drainage it is a sough. If a drivage is straight and on a constant gradient however steep, it is primarily for access and transport (including ventilation) or for exploration it is a drift. Both ends of a drift can be underground or one end might be at the surface. mikeL 16 05 10 (Added by 92.238.234.205 (talk) 23:04, 16 May 2010)
Wastewater edit
If someone has appropriate expertise, I think it would be worth tying in some mention of tailings and possibly general legacy metal mine water pollution and treatment. 5v5h1 (talk) 12:30, 2 December 2020 (UTC)
