(Southern African Institute of Mining and Metallurgy, 2015-04)Water is a very important component in the production process at underground coal mines. Current unfavourable economic conditions have forced the coal mining industry to identify and address every possible bottleneck ...
-
(Southern African Institute of Mining and Metallurgy, 2015-04)‘Roof support awaiting time’ (RSAT) is a term used at Goedehoop Colliery’s Simunye Shaft to describe the potential production time lost due to the continuous miner (CM) standing idle waiting for roof support to catch ...
-
(Southern African Institute of Mining and Metallurgy, 2015-06)This article investigates the complex problem of a budgeting process for a large mining operation. Strict adherence to budget infers that financial results align with goals. In reality, the budget is not a predetermined ...
-
(Southern African Institute of Mining and Metallurgy, 2015-06)The aim of any mine design is to ensure that the excavations remain stable for the period they will be in use. Various pillar systems are used to ensure that underground stopes remain stable and that mining activities ...
-
(Southern African Institute of Mining and Metallurgy, 2015-02)This paper discusses a study that investigated different underground bulk air heat exchanger (>100 m3/s) design criteria. A literature review found that no single document exists covering all design criteria for different ...
-
(Southern African Institute of Mining and Metallurgy, 2014-12)Contrary to the way it is often portrayed, the average organization or company is far from being a cold, calculating machine. It is actually a highly emotive place where interaction with people is a fundamental part of ...
-
(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, 2014-12)Since the dawn of mining, pillars have been used as primary support to ensure stable workings. Early designs were based on trial and error, after which more scientific means developed over time. A vast amount of progress ...
-
(Southern African Institute of Mining and Metallurgy, 2014)Methane explosions in underground coal mines are a major concern across the mining industry. After the Pike River disaster, Arnot Coal became even more aware of the explosion risk. To determine whether Arnot has adequate ...
-
(Southern African Institute of Mining and Metallurgy, 2013-12)As a result of the rising electrical energy costs in South Africa, a method was sought to reduce the overall electrical consumption of typical shaft systems. A typical shaft configuration was analysed and the primary ...
-
(Southern African Institute of Mining and Metallurgy, 2013-04)Compressed air is widely used on South African gold mines. However, due to recent and proposed future electricity tariff increases it is quickly becoming too expensive to produce and use. Boxfront chute systems at ore ...
-
(Southern African Institute of Mining and Metallurgy, 2013-04)Following the blasting fatality on 17 December 2009, Landau Colliery was forced to change from the blasting practices that had been utilized since the start-up of the mine. Since then, attempts have been made to optimize ...
-
(Southern African Institute of Mining and Metallurgy, 2013-06)The mining industry in South Africa faces real challenges with regard to the reduction of safety-related incidents. The purpose of this paper is to highlight the need for alternative interventions in addition to other ...
-
(Southern African Institute of Mining and Metallurgy, 2012-08)It has been established that significant time-dependent stope convergence may occur over time periods of hours and days in certain hard-rock gold and platinum mines. The source of this time-dependent behaviour appears ...
-
(Journal of Contemporary Management, 2013)This paper compares the organisational strategic drivers of a South African mining house with those of industries abroad. It furthermore compares the key competencies or capabilities of the mining house with those of the ...
-
(Southern African Institute of Mining and Metallurgy, 2012-04)The purpose of the project was to investigate the challenges faced by Khutala Colliery pertaining to underground road construction and maintenance. Furthermore the influence of these challenges on productivity and safety ...
-
(Southern African Institute of Mining and Metallurgy, 2012-04)The utilization of centralized blasting systems is progressively becoming a feature of the South African mining industry, owing to increased pressure from the Department of Mineral Resources (DMR) to ensure safer blasting ...
-
(Southern African Institute of Mining and Metallurgy, 2012-04)Anglo American Platinum’s Khomanani 2 shaft changed over from down-dip mining to breast mining in 2004. The changeover was made to ensure that production targets were met, as it was said that predevelopment for down-dip ...
-
(Southern African Institute of Mining and Metallurgy, 2011-12)A value assessment model which uses deal objectives, financial and non-financial indicators as a guide to assess value creation in mergers and acquisitions. The extent to which post- merger deal objectives are achieved ...
-
(Taylor & Francis, 2012-06)There is mounting evidence to show that engineers need more than technical skills to succeed in industry. In this paper we describe a curriculum innovation in which so-called “soft” skills, specifically inter-personal ...
