A long hole stoping system for mining narrow platinum reefs

The Journal of The South African Institute of Mining and Metallurgy APRIL 2002 151 Introduction In South African metalliferous mines, stoping operations are largely confined to narrow, tabular orebodies making mechanization extremely difficult. Limited flexibility in terms of stope width has necessitated drilling by means of hand held, pneumatic rock drills at most of our operations. As the

Mining all of the reef, all of the time Mining Review

21/01/2020· South Africa’s reef deposits, especially gold and platinum-bearing ore bodies, are narrow and tabular. While legislation dictates a minimum operation height of 800 mm in areas where people work, some of the country’s narrow reef mines have ore bodies with thicknesses of less than 500 mm, which results in ore dilution, as waste ore with zero economic value is also mined. “Mining is the

It has largely been replaced by mechanized methods but is still used in many small mines around the world. Shrinkage stoping is a short-hole mining method which is most suitable for steeply dipping orebodies (70°- 90°). Also, the blasted ore must not be affected by storage in the slopes (e.g., sulfide ores have a tendency to oxidize and decompose when exposed to air). Its most prominent
