Mine shafts and workings were filled with ground water. In 1992, failure of an adit plug forced 50,000 m 3 of mine drainage being released to Fal Estuary and Carnon river leading to environmental damage.

Shaft Mining, Mining Techniques, Underground Mining ...

Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron, coal, etc. which can be found at the depth of the earth's surface. It is found mostly all over the world. Shaft sinking refers to shallow shafts and it is different from a ...

Sri Lanka: From Mine to Market, Part 1 Research News

30/09/2014  To give an idea of scale, the standard pit mine in Sri Lanka consists of a vertical shaft that measures two by four meters. If the pits are deep and in harder ground, the miners might dig a two by two meter square pit or a two-meter round pit. Depth can range up to 50 meters, though most pits are between 5 and 25 meters.
