DEVELOPING NEW APPROACHES TO ROCK SLOPE STABILITY ANALYSES (2006)
This paper describes mining industry funded research that is being undertaken to address the critical gaps and uncertainties in our knowledge so that we can develop new approaches and create more effective ways for predicting the reliability of rock slopes ...

GEOTECHNICAL DESIGN CONSIDERATIONS FOR THE PROPOSED OYU TOLGOI OPEN PITS, SOUTHERN MONGOLIA (2006)
The Oyu Tolgoi porphyry gold and copper project is located in the south Gobi region of Mongolia. The Ivanhoe Mines project has the potential to become a long-life copper and gold producer that could rank among the largest in the world. The development of the ...

GROUND CONTROL AT LEINSTER NICKEL OPERATIONS (2006)
Leinster Nickel Operations, located in Western Australia, consists of an underground and three open pit mines in relatively adverse ground conditions. This paper reviews our ground control practices in the open pits, covering aspects of ground support, wall ...

INTERACTION BETWEEN THE BLOCK CAVE AND THE PIT SLOPES AT PALABORA MINE (2006)
The Palabora Mining Company has successfully extended the life of its operation by developing a 30,000tpd block cave underground mine below the now closed open pit. The process of transitioning from surface to underground mining has been technically, operationally ...

MONITORING THE STABILITY OF SLOPES BY GPS (2006)
In this paper a slope stability monitoring system is described. It consists of displacement measurements by GPS, and a back analysis of measured data. The use of GPS has a great advantage, because of the fact that continuous displacement measurements with ...

OPEN CAST PIT SIDEWALL COLLAPSE – QUO VADIS INSURANCE? (2006)
Insurers are hesitant to provide coverage for Open cast Pit side wall collapse, and even the consequent damage to plant and equipment in the pit as well as the resulting interference with the mining operations. After a general introduction to relevant principles ...

PIT SLOPE DESIGN AND RISK – A VIEW OF THE CURRENT STATE OF THE ART (2006)
Risk lies at the heart of all mining and nowhere more so than in pit slope design. Mining is principally about two areas of risk; safety and economics. This paper addresses the main elements of pit slope design and presents a view of the state of the art in ...

PIT WALL FAILURES ON “UNKNOWN” STRUCTURES (2006)
A number of impending and actual pit wall failures have been observed and documented which have been interpreted to initiate on newly generated structural features. This infers failure through intact rock. Failure mechanisms have been postulated resulting ...

SEISMOLOGY AND SLOPE STABILITY IN OPEN PIT MINES (2006)
The implementation of routine real-time micro-seismic monitoring of open pit mine slopes has been discussed. Some examples of seismic arrays have been given, and a recommendation of suitable seismic sensors made. Unfortunately near-surface sensors are required ...

SLOPE OPTIMIZATION AT ESCONDIDA NORTE OPEN PIT (2006)
The feasibility study of Escondida Norte (ENorte), recommended a slope angle design for the Final Pit. But, according to the experience obtained with the slope adjacent to the West wall of ENorte, in which Compañia Minera Zaldívar (CMZ) gained in its phase ...
