Primary diamond deposits have been mined on an industrial scale only within the past 150 years, mainly as open pit operations. Underground mining of these deposits was implemented only within the second half of the 20th century in South Africa and over the last 50 years, a relatively large Read more... about Underground Mining at Ekati and Diavik Diamond Mines

Evolution Mining's Frog’s Leg underground mine experienced an increase in the number of seismic events and rockburst occurrences during 2015. This was due to increased stress levels due to increasing mining depth and unfavourable mining geometry (mining the sole remaining

Arenal Deeps is an Au mine located near Minas de Corrales, Uruguay, which was exploited via an open pit operation from 2004 until 2009 and underground since then, using both inclined room and pillar and transversal stoping methods. The progression of mining activities (down to ~320m BGS) has led Read more... about Application of numerical methods to underground excavations

In underground mining, there are a number of uncertainties in the ground support design process and during implementation of ground support designs. The minimisation of geological uncertainty is one of the rock engineering principles outlined by Bieniawski (1992) and by Stacey

Arenal Deeps is an Au mine located near Minas de Corrales, 400km north of Montevideo, Uru- guay. The Arenal deposit is a subvertical fault zone, 6m – 30m wide, which was exploited via an open pit op- eration from 2004 until 2009 and underground since then. Underground mining is developed using Read more... about Arenal Deeps: application of numerical methods to two- and three- dimensional stability analyses of underground excavations
