A review of EN 16907 on earthworks (extractive waste) in the context of South African mine residues (Southern African Institute of Mining and Metallurgy, 2022-06)Rather quietly, a new generation of European norms dealing with earthworks has been developed over the past few years, in particular a part of EN 16907 pertaining to extractive waste. Whereas the majority of the parts ...

A case study of geotechnical conditions affecting mining-induced seismicity in a deep tabular mine (Southern African Institute of Mining and Metallurgy, 2022-03)Seismic risk in the deep gold mines of South Africa has been studied for many decades. A clear understanding of the effect of geotechnical conditions on the seismic hazard nevertheless remains elusive. Certain reef types ...
-
(Elsevier, 2022-09)Longwall coal mines in the Bowen Basin of Australia are highly productive and gassy, comprising many coal seams above the working seam. Predictive modelling of specific gas emission (SGE) using the conventional Winter model ...
-
(Elsevier, 2022-12)Over the past few years, the Australian coal mines heavily relied on drilling vertical goafholes to capture coal mine methane and monitor methane levels, which is named goaf gas drainage. The suction pressure applied on ...
-
(University of Pretoria, 2023)The value of digital information is ever-increasing as more companies utilize digital technologies such as Artificial Intelligence (AI) and the Internet of Things (IoT) to gain deeper insight into their business operations ...

A limit equilibrium model to simulate the large-scale pillar collapse at the Everest Platinum Mine (Springer, 2023-01)This paper is a case study of a large-scale pillar collapse at the Everest Platinum Mine. A major contributing factor to the collapse was the presence of weak alteration layers in the pillars. These alteration layers are ...
-
(Southern African Institute of Mining and Metallurgy, 2021-12)South Africa is one of the leading producers and exporters of coal globally. A significant amount of the country’s production is obtained from previously mined underground bord and pillar workings. This coal is in the ...
-
(Southern African Institute of Mining and Metallurgy, 2021-05)This paper describes some important aspects associated with historical underground measurements in South African gold and coal mines. Deformation measurements were used to confirm the use of elastic theory to simulate ...
-
(Southern African Institute of Mining and Metallurgy, 2021-01)The real cost of any mining incident has, empirically, proven to be estimation-driven, rather than factdriven. One of the main reasons for this lies with the complexity of the cost composition of any given mining incident. ...
-
(Southern African Institute of Mining and Metallurgy, 2021-08)In 2015, after amendments to the explosives regulations, stemming became a mandatory activity for all South African mining operations. There are, however, circumstances in which it is thought stemming has an adverse ...
-
(Southern African Institute of Mining and Metallurgy, 2021-05)Spontaneous combustion (SC) is a cold oxidation reaction that generates heat, causing a temperature rise of the reactant and leading, with limited heat dissipation, to self-ignition of the reactant, which occurs without ...
-
(Springer, 2021-01)An improved understanding of pillar strength and pillar failure mechanisms is required to optimize tabular mine layout designs. The paper describes the application of a limit equilibrium model for pillar failure analysis. ...
-
(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 ...
-
(Elsevier, 2021-06)This paper investigates the use of a thin spray-on liner (TSL) as stope face support in narrow width tabular stopes. The application of areal support is difficult in these stopes because of the small stoping width and the ...
-
(Southern African Institute of Mining and Metallurgy, 2020-12)Since 2010, a number of researchers have investigated the development of new models to generate accurate predictions relating to the risks from flyrock. The purpose of this paper is to summarize and analyse these recent ...
-
(Southern African Institute of Mining and Metallurgy, 2020-06)Thorncliffe Chrome Mine, one of Glencore’s Eastern Chrome operations, is currently mining the Middle Group No.1 (MG1) chromitite layer and is conducting a pre-feasibility study for an expansion project to mine the Middle ...
-
(Springer, 2021-03)During underground longwall coal extraction, overburden strata deformation may result in vertical goaf drainage holes, which are drilled in advance of mining for tail gate gas management, to fail. The performance of these ...
-
(University of Pretoria, 2014-01)Mining is a hugely expensive process and unlike manufacturing is based on an ever diminishing resource. It requires a continuous infusion of capital to sustain production. A myriad of factors, from the volatility of the ...
-
(Mine Ventilation Society of South Africa, 2019-01)The use of high powered catalogued auxiliary fans to meet the ventilation requirements of fairly shallow mines is common practice and often is not an energy efficient ventilation solution. This paper describes the ...
-
(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 ...
