(University of Pretoria, 2015)Crush pillars are used as part of the stope support in intermediate depth tabular mining stopes. Crush pillar design should ensure that the pillars crush when formed at the mining face. This behaviour of the pillars is ...
-
(Southern African Institute of Mining and Metallurgy, 2009-02)When designing coal mine roof support, it is necessary to account for the uncertainties and variability that inherently exist within the rock mass and support elements. The performance of a support system is affected by ...
-
(Southern African Institute of Mining and Metallurgy, 2011-12)This paper gives an overview of the difficulties associated with determining the strength of hard-rock pillars. Although a number of pillar design tools are available, pillar collapses still occur. Recent examples of ...
-
(Southern African Institute of Mining and Metallurgy, 2011-12)Beatrix Gold Mine, a deep-level gold mine in the Free State province of South Africa, has the highest methane emission rate of any gold mine in the country. Methane is emitted from underground sources intersected during ...
-
Determining the physical and economic impact of environmental design criteria for ultra-deep mines (University of Pretoria, 2007-07-24)Please read the abstract in the section 00front of this document
-
(University of Pretoria, 2019)Flyrock remains a significant risk to the health and safety of the mine’s employees and infrastructure as well as the safety of the neighbouring communities and their property. Losses and damages can result in significant ...
-
(Southern African Institute of Mining and Metallurgy, 2019-07)AfriTin Mining Limited plans to reopen the Uis tin mine in Namibia and establish a pilot processing plant for phase 1 of the Uis tin project, which is scheduled to commence in the last quarter of 2018 . A mining plan is ...
-
(University of Pretoria, 2009-12-09)The ability of an explosive to break rock is influenced considerably by the extent of confinement in the blasthole and it is believed that confinement is improved by the use of stemming. The aim of this paper is to present ...
-
(Elsevier, 2020-12)In the past decades, attempts were made to build a systematic approach to mining method selection (MMS) Ooriad et al. This is because MMS is a complex and irreversible process. Since it can affect the economic potential ...
-
(Springer, 2023-12)Entrapments are a huge risk in underground mines. This happens when miners (or any other persons who have entered underground) survive the initial event of an accident, become trapped or lost in unknown and life-threatening ...
-
(Southern African Institute of Mining and Metallurgy, 2011-12)No abstract available.
-
(University of Pretoria, 2007-11-09)In general, as the uniaxial compressive strength of rock samples is tested, the uniaxial strength of the rock decreases with increasing sample size until a strength is reached beyond which no further decrease in strength ...
-
(University of Pretoria, 2015)In mining, the loading environment on pillars is highly complex with combinations of normal and shear stresses. It is also understood that with an active and working face, constant redistribution of stresses will occur to ...
-
(Mine Ventilation Society of South Africa, 2016-04)Dust emissions from mining activities and their impact on the surrounding environment have been and remain one of the major environmental impacts associated with surface mining. Dust emissions caused by the transportation ...
-
(Southern African Institute of Mining and Metallurgy, 2014-12)Escalating energy and electricity costs have become one of the largest drivers of expenditure in mining operations. Over the last eight years, energy costs have tripled when expressed as a percentage of total expenses in ...
-
(Southern African Institute of Mining and Metallurgy, 2009-05)The classical limit equilibrium methods are suspected to be ineffective in predicting the potential for highwall failure in many instances in coal mines around the world. Slope engineers have for many years recognized a ...
-
(University of Pretoria, 2014)This document describes the re-engineering principles applied in the design of a personnel transportation system for a platinum mine in the Rustenburg area of South Africa. It incorporates conveyor belt travelling, chairlift ...
-
(Southern African Institute of Mining and Metallurgy, 2016-05)This article describes the re-engineering principles applied in the design of a personnel transportation system for the Bafokeng Rasimone Platinum Mine in the Rustenburg area of South Africa. It incorporates conveyor belt ...
-
(University of Pretoria, 2008-08-06)This thesis addresses the problem of designing roof support systems in coal mines. When designing the roof support, it is necessary to account for the uncertainties that are inherently exist within the rock mass and support ...
-
(Mine Ventilation Society of South Africa, 1999-01)The project was planned in two phases. The first phase involved laboratory tests on a continuous miner model for different ventilation and spray systems at the newly built ventilation simulation tunnel at the Klopperbos ...
