Disused Mines and Shafts - Health and Safety Authority

Disused mines and shafts can be a major problem in many parts of Ireland. In the past, a common practice was to close mining sites, with little consideration given to the need to make these sites fully safe. With better regulation and the existence of the Environmental Protection Agency it is hoped that this practice is a thing of the past.

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 ...
