Project Showcase
Client: Oyu Tolgoi
Location: Mongolia
Status: Current
RSV International is currently designing Shaft no. 2 on the Oyu Tolgoi Project in Mongolia. This will be one of two initial production shafts that will handle ore from the underground block cave operation.
Shaft no. 2 is 10m in diameter and its head frame towers 31 stories above the Gobi desert. The concentrator is designed to process 100 000 tonnes per day which will initially be mined from the open-pit operations. The tonnage will be increased to 160 000 tonnes per day from the underground operations. Full commercial production is set for 2013. Oyu Tolgoi will produce 1.2 billion lbs of copper and 650 000 oz of gold per annum for the first ten years. It is anticipated that it will take up to 100 years to mine this deposit.
Client: Impala Platinum
Location: Rustenburg, North West Province, South Africa
Status: Completed 2013
The Impala Platinum 16 Shaft project consisted of a vertical shaft mine with a second ventilation shaft. RSV was involved in the project from its inception in March 2002 through to the project close-out stage in 2013. Through innovation and specialist skills, RSV ensured that the project was completed safely and ahead of schedule.
The project is located in the Rustenburg area which is rich in various metals, particularly platinum. The main shaft is 1 650m deep and has a diameter of 10m. The ventilation shaft is the same depth with a diameter of 6.8m. The headgear stands at 108m and is the tallest in the world. The shaft is expected to deliver 256 000 tonnes of reef and ore per month.
RSV has been involved in the project since the beginning in March 2002. By using innovative techniques and specialist skills, we ensured that the project was completed ahead of schedule by more than two years.
Client: Anglo American Platinum
Location: Rustenburg, North West Province, South Africa
Status: Current
RSV has been involved with the Anglo American Platinum Bathopele Project since 2007, having been contracted to conduct the initial Conceptualisation, Pre-feasibility and Feasibility Studies. The Bathopele Project exploits the remaining UG2 reserves at the Bathopele Mine and is primarily a mechanised operation.
The UG2 reef will be mined using mechanised board and pillar extraction and conveyor belt ore removal. The project is a replacement project and will maintain the shaft capacity at 270ktpm.

In August 2008, RSV and GOBA were jointly awarded the EPCM contract for the engineering, procurement and construction management of a new 10.6 Mt/a underground coal mine. This project will serve as a replacement mine for production from the current Twistdraai Colliery to supply Sasol Synfuels.
The project included the development of shaft systems (service, ventilation and decline shafts), as well as the development of material handling systems, including a surface 18km overland conveyor, surge bunker and underground conveyors and surge bins. The project scope further included all supporting mine infrastructure, including offices, workshops, changehouses, water supply and power supply.
This was a 50:50 joint venture between RSV and GOBA (Pty) Ltd. The project was designed and constructed to accommodate the first production section in January 2012 and build-up to full production within 12 continuous miners and three stonework sections by 2015. The mine will produce product for both Sasol Synfuel and the export market.

Status: Current
In 2009 RSV and GOBA were awarded the EPCM contract for the engineering, procurement and construction management of a new 8.5Mtpa underground coal mine, which is upgradable to 10.5Mtpa. This project will serve as a replacement mine for production from the current Brandspruit Colliery.
The project includes the development of shaft systems (service, ventilation and decline shafts); development of material handling systems (surface 28km overland conveyor, surface surge bunkers, underground conveyors and surge bins); all supporting mine infrastructure, including offices, workshops, changehouses, district road upgrades, mine roads and parking, power supply and distribution, communication systems, water supply and reticulation, sewage and waste water handling and pollution control).

Client: Lonmin Platinum
Location: Marikana, North West Province, South Africa
Status: Completed January 2011
In May 2008, RSV was appointed by Lonmin Platinum to conduct a Feasibility Study for its Karee 3 Shaft UG2 Sub-decline. Following this, RSV was awarded the EPCM contract that included commissioning and hand-over. The project entailed the sinking of a conveyor/material decline with four levels and establishing the infrastructure of the decline bottom. Parallel to the conveyor/material decline would be a chairlift decline with both declines at -9 degrees to the horizontal and levels at 36 metres apart.
A 250kW single drum winder was installed above the main levels which served as the main access level to the decline. The winder was equipped with the Gondola system for material transport. All services were installed between the conveyor and the material sides in the decline and forms a barrier between the two systems. An ore pass system was linked from the decline to the main level from where the rock is transferred into the vertical shaft main ore pass system.
