2014-10-31 rock-cutting mining methods. Suitability of platinum orebodies for rock-cutting methods Overall geological conditions Rock-cutting methods would largely be focused on on-reef mining layouts with little or no infrastructure located outside the reef envelopes. The major economic reefs in the BC are the UG2 and Merensky reefs, which are narrow and

2021-3-24 The platinum orebody is a thin, tabular reef covering a vast area. This enables a progressive method of mining which includes the drilling of the reef and blasting it to advance the face. It combines the increased use of industralization and trackless-mining methods in steps. Platinum mining, however, differs from gold mining in different ways.

2018-8-21 The East Shaft of this fully mechanised low-profile board-and-pillar operation mines a single seam of UG2 Reef at an average of about 1.95m stoping width (in some cases the UG2 Reef can be as narrow as 80cm). The teams in the Central Shaft operate in stoping widths of about 2.2m on average and they mine dual seams of UG2 Main and Leader reefs.
