Quantified Value-created Process (QVP) - A value-based process for mine design and operating decisions

Publikováno v: Journal of the Southern African Institute of Mining and Metallurgy. 122:1-10

This paper introduces the Quantified Value-created Process (QVP), a decision-making process for use in mine design and operation. The implementation of the QVP is founded on a ten-step rock engineering design process and a ten-step strategic planning

Synthetic Rock Mass Modelling and Geotechnical Mapping: An Open Pit Mine Case Study in Anisotropic Rock

Autor: T. Russell, T.R. Stacey, M. Bester

Publikováno v: International Journal of Mining, Reclamation and Environment. 35:356-378

Most pit boundaries at Sishen Mine in South Africa consist of Banded Iron Formation (BIF), which exhibits anisotropic behaviour on a rock mass scale. A generally applicable approach is to apply Syn...

Experimental and Analytical Investigations of the Effect of Hole Size on Borehole Breakout Geometries for Estimation of In Situ Stresses

Autor: Joung Oh, H. Lin, T.R. Stacey, Ismet Canbulat

Publikováno v: Rock Mechanics and Rock Engineering. 53:781-798

Borehole breakout is a natural phenomenon in boreholes drilled in rock due to the induced stress concentration. Many researchers have attempted to correlate this phenomenon with in situ stress magnitudes. In this paper, a series of true triaxial test

Value creation as an approach to the management and control of rockburst damage in tunnels

Autor: K.A. Moganedi, T.R. Stacey

Publikováno v: Tunnelling and Underground Space Technology. 83:545-551

Energy absorbing support systems have the potential to contain or prevent rock mass damage on the periphery of underground excavations during a seismic event. Containing rockburst damage can protect employee safety, improve stakeholder relations and

Sensitivity of shotcrete Brazilian discs coated with thin spray-on liners to environmental conditions

Autor: T.R. Stacey, M.J. Kanda

Publikováno v: Journal of the Southern African Institute of Mining and Metallurgy. 121

SYNOPSIS Thin spray-on liners (TSLs) have been used as sealants and rock support in tunnels for over 25 years. Laboratory tests have indicated satisfactory properties that can provide adequate strength, adhesion, toughness, and elasticity as part of

Tensile strength sensitivity of thin spray-on liners to changes in environmental conditions

Autor: T.R. Stacey, M.J. Kanda

Publikováno v: Journal of the Southern African Institute of Mining and Metallurgy, Volume: 120, Issue: 4, Pages: 251-259, Published: APR 2020

Thin spray-on liners (TSLs) are an areal support with the perceived ability of promoting rock mass stability, based on their high tensile strength and elongation capacity. However, these benefits are not always realized in the mining environment, whi
