ModernMining July 2018The difference that technology and efficient mine planning can make to the operating margins of mines is well illustrated by the initiatives that Kumba Iron Ore has taken its Sishen and Kolomela mines in the Northern Cape. At Sishen, for example, the current fleet of mining trucks is significantly smaller than it was in 2015 and yet is handling more material, as our article on Kumba in this issue explains.

Comment – Tati Belt’s mysterious wall

Mike Main, the author of a number of books on Botswana, is looking for help from Modern Mining’s readers. He has come across a wall, which he describes as a “remarkable structure”, in the Tati Greenstone Belt near Francistown and is trying to pin down when it was built, by whom and to what purpose. The wall is located close to the site of ‘Old Tati Town’, a small gold mining settlement which sprung up in the late 1860s and which was finally abandoned in the 1890s. Read more …

Automated low-profile cable bolter launched by Sandvik

Sandvik has launched the DS221L rock reinforcement cable bolter with one-hole drilling, which it believes will significantly improve safety and productivity in underground mining operations. The prototype machine was developed in close collaboration with the Two Rivers platinum mine in South Africa, where it underwent a successful 12-month trial. In digitalised environments the rig is compatible with Sandvik’s OptiMine® monitoring system. Read more …

Sasol inaugurates Shondoni

Sasol has officially opened its new R4,5 billion Shondoni colliery in Mpumalanga as part of its R14 billion mine replacement programme. Distinguishing Shondoni from Sasol’s other collieries is the use of renewable energy, which includes the use of solar geysers, heat pumps and maximum utilisation of natural light. The mine also holds the record of having the longest – at 21 km – single flight conveyor without an intermediate booster drive in Africa. Read more …

Technology drives down costs at Kumba

Over the past several years, South Africa’s leading iron ore producer, Kumba, has responded to the weak iron ore price by introducing a series of state-of-the-art – but proven – technologies at its two Northern Cape mines, Sishen and Kolomela, which have boosted productivity and driven down operating costs. Modern Mining was able to see some of the new technology when it visited Sishen recently. The mine is one of the largest open-pit operations in the world, moving well over 200 Mt of material a year.

Kalahari Copperbelt about to realise its full potential

After a false start with the Boseto open-pit mine of Discovery Metals, Botswana’s Kalahari Copperbelt is on the brink of realising its early promise, with two new mines – the T3 (Motheo) project of Tshukudu Metals Botswana and the Zone 5 project of Khoemacau Copper Mining – on the horizon. T3 – which is still awaiting a final development decision – will initially be an open-pit mine while Khoemacau is planning a mechanised underground mine at Zone 5, with early construction works due to start later this year.
