  • Reef Adjacent to Structures at Tautona Mine, Anglogold Ashanti South African Operations
    Reef Adjacent To Structures at TauTona Mine, AngloGold Ashanti South African Operations DE DAVIES Section Manager TauTona Mine, AngloGold Ashanti South African Operations SYNOPSIS The paper describes the extraction of reef adjacent to geological structures in the Carbon Leader Reef Section at TauTona Mine. Traditionally long wall mining has left feasible and economical blocks of ground adjacent to structures when negotiating major geological features. This meant that mining through an up- throw fault, rolling to the reef elevation on the displaced side of the fault left reef in the long wall. High grade areas were abandoned and gold was sterilized. In these tight economic times and with the need to continuously improve safety standards the need arose to develop a technique to extract these blocks economically and safely. It was believed that the structures in these abandoned areas were de-stressed and could now be mined in small volumes at a high grade. The term RATS is an acronym derived from “reef adjacent to structures” and aptly describes the process of identifying and extracting these blocks. The viability of this method was addressed in terms of the mine design, underground investigations and financial risks. The paper concludes with an analysis of the successes achieved to date. 1 INTRODUCTION TauTona Mine is one of the AngloGold Ashanti Southern Africa operations. It is close to the town of Carletonville in the province of Gauteng and about 70km south-west of Johannesburg. TauTona is 46 years old and employs ± 4 000 people. Mining operations are conducted at depths ranging from 1,800m to 3,500m at which the world’s deepest stoping sections are found.

    Scheepers, L.J, Stability of access ways in ultra high stress – The next step SANIRE 2004 – The Miner’s Guide through the Earth’s Crust, South African National Institute of Rock Engineering Stability of access ways in ultra high stress – The next step L.J. Scheepers TauTona Mine ABSTRACT Stability of access tunnels through high stressed abutments remains a problem associated with deep level mining. The problem is compounded by the presence of faults or dykes in these abutments or pillars as large seismic events can occur on such features. This paper describes a novel way of ensuring the long-term stability of access tunnels through high stressed areas by mining an off reef de-stressing slot 7m above the tunnel simultaneous with and leading the development of the tunnel. 1 Introduction Republic of South Africa. Figure 1 shows the location of TauTona Mine in the West Rand Area. With all mining operations the stability of the access ways to the ore bodies are crucial for sustained safe Two economically viable gold-bearing orebodies are production. In deep level operations, quasi-static exploited within the TauTona Mine boundary area, stress related instabilities must be catered for with namely the younger and shallower Ventersdorp layout and support design of the access ways. In Contact Reef (VCR), and the older, deeper Carbon addition possible seismic loading on the access ways Leader Reef (CLR). must also be catered for. This is certainly true for TauTona Mine. At TauTona the CLR has been accessed and mined from depths between 2500 and 3600 metres below surface for an area of approximately 5000m on strike by 3500m on dip within the lease area.

  • Anglogold A/R Front (P1-40)
    Key features 2000 Gold production increases by 5 per cent to 7.2 million ounces and operating profit rises by 6 per cent to R3.3 billion. Headline earnings decline by 11 per cent to R1.77 billion, mainly as a result of a focus on growing the business and the consequent increase in net interest paid. Integration of AngloGold Australasia (formerly Acacia Resources) into AngloGold, providing a sound foothold in this key gold-producing region, together with the inclusion of AngloGold in the All Ordinaries Index on the Australian Stock Exchange in January 2000. The AngloGold share is now tradeable around the world for 24 hours a day. Approval for construction of the Yatela mine in Mali in February 2000 at a capital cost of some $76 million. Production will begin in June 2001. Acquisition in July 2000 of 25 per cent of OroAfrica, the largest manufacturer of gold jewellery in South Africa, for $8 million (R55 million). Acquisition in July 2000 of a 40 per cent interest in the Morila mine in Mali for $132 million, with a project finance provision of $36 million. AngloGold manages this operation. Purchase of a 50 per cent stake in the Geita mine in Tanzania for $205 million, with a project finance provision of $67 million. The mine was officially opened on 3 August 2000. AngloGold has entered into a further strategic alliance with Ashanti Goldfields Limited to seek opportunities for working together in Africa.

Mineral Resources are inclusive of the Ore Reserve component unless otherwise stated. Mineral Resources The 2006 Mineral Resource increased by 14.1 million ounces to 181.6 million ounces before depletion. After a depletion of 8.3 million ounces, the net increase is 5.8 million ounces. Mineral Resources were estimated at a gold price of $650 per ounce in contrast to the $475 used in 2005. The increased gold price resulted in an increase of 5.8 million ounces while successful exploration and revised modelling resulted in a further increase of 7.6 million ounces.

  • Earthquake Rupture at Focal Depth, Part I: Structure and Rupture of the Pretorius Fault, Tautona Mine, South Africa

Geophys. 168 (2011), 2395–2425 Ó 2011 Springer Basel AG DOI 10.1007/s00024-011-0354-7 Pure and Applied Geophysics Earthquake Rupture at Focal Depth, Part I: Structure and Rupture of the Pretorius Fault, TauTona Mine, South Africa 1,2 1,3 1 V. HEESAKKERS, S. MURPHY, and Z. RECHES Abstract—We analyze the structure of the Archaean Pretorius 1. Introduction fault in TauTona mine, South Africa, as well as the rupture-zone that recently reactivated it. The analysis is part of the Natural Earthquake Laboratory in South African Mines (NELSAM) project Fault-zones typically move by infrequent earth- that utilizes the access to 3.6 km depth provided by the mining quakes that are localized along weak surfaces and operations. The Pretorius fault is a *10 km long, oblique-strike- separated by inter-seismic periods of tens to thou- slip fault with displacement of up to 200 m that crosscuts fine to very coarse grain quartzitic rocks in TauTona mine. We identify sands of years. Fault healing between earthquakes here three structural zones within the fault-zone: (1) an outer may renew fault strength and its rupture resistance damage zone, *100 m wide, of brittle deformation manifested by (MARONE, 1998;MUHURI et al., 2003;SIBSON, 1985). multiple, widely spaced fractures and faults with slip up to 3 m; (2) an inner damage zone, 25–30 m wide, with high density of anas- This earthquake cycle terminates when the fault tomosing conjugate sets of fault segments and fractures, many of becomes quiescent due primarily to changes in tectonic which carry cataclasite zones; and (3) a dominant segment, with a activity.
