benefits in the case of narrow reef gold mines. It is suggested that many marginal mines should seriously consider SBM. Benefits can also be realised in platinum mines, but a lot more experimental work is necessary to establish cost parameters more reliably. Some practical experience in the use of SBM in the mining of the UG2 reef is presented.
Finally, leading from an early idea to extract ore by drilling narrow orebodies, Anglo American partnered with to develop a platinum reef drilling system called Slot Borer. The cutting system is based on proven raiseboring technology and deploys the TBMstyle steel discs in
has completed the first prototype of a cable bolter for narrowreef mining with such functionality, which is in the testing phase of development. as we believe platinum is the toughest

PGM grades and ratios of Platinum (vs Palladium) The UG2 Reef, a chromiterich reef, is more consistent, but lacks Merenskys high yield of Gold, Copper and Nickel byproducts. In the last decade, PGM miners recover chromite as a separate product Platreef is a wider reef with lower PGM values, but higher base metal content (c. 5 times) 5
Electric narrow reef XLP mining coming to Anglo Platinums Another highlight of Anglo American Platinums just released 2019 report was the revelation that electric narrow reef mechanised equipment is set for trials at its Tumela 15E underground platinum Another highlight of Anglo American Platinums just released 2019 report was the revelation that electric narrow reef
The solutions DOKING provided in designing and manufacturing the first extra low profile equipment proved to be successful in the platinum mining application. The references acquired so far put DOKING very high on the success scale because of the following features of the company:
At Modikwa Platinum Mine, one of South Africas leading platinum mines, you will find some machines which perform Herculean feats in places that they have very little right to be in. Up to 800m underground in the mine, drill rigs and load haul dumpers powered by MTU Series 900 engines, add significantly to Modikwas profitability through their performance, durability and efficiency.
source of 42% of ore processed by Anglo Platinum. The Plat Reef, briefly mined in the 1920s, was not exploited on a large scale until 1993. One of the biggest challenges of mining the UG2 is that the reef is very narrow (6080cm). A large amount of injuries occur at the stope face of narrow reef mines. Mining companies realise
2. MM 220 Reef Miners. Also in development with is another remotely operated rig, the MN 220 Reef Miner. This incorporates cutting and roof bolting and is designed for mining narrow mineral reefs in hard rock. It is up to three times faster than conventional drill amp; blast methods and, of course, also removes our people from harms way.
mechanize narrow reef mining. This particular project started in 1998. Initial trial The Union Section of Anglo Platinum purchased a Solo H 606 RA long hole drilling rig from Tamrock in 1997. In order to evaluate long hole drilling as a basis for face mechanization. The Solo series of drill rig was selected
