Achieving energy efficiency with medium voltage variable speed drives for ventilation-on-demand in South African mines
Nel, Andries J.H.; Arndt, Deon C.; Vosloo, Jan C.; Mathews, Marc J. (Elsevier, 2019)The sustainability of the mining industry is contingent on the industry's ability to improve upon the status quo of operational efficiency. The advancement of energy efficient technologies coupled with modern strategies ... -
Automated electricity bill analysis in South Africa
Goosen, P.; Mathews, M.J.; Vosll, J.C. (Univ Stellenbosch, 2017)The ever-increasing cost of energy puts industries under pressure. Industries are forced to monitor their energy consumption and to manage energy more efficiently and responsibly. Some industrial companies have multiple ... -
Case study: energy savings for a deep-mine water reticulation system
Vosloo, Jan; Liebenberg, Leon; Velleman, Douglas (Elsevier, 2012)In deep level mining, water reticulation systems are one of the major consumers of electricity. The refrigeration plants, together with the underground water supply and dewatering systems are integrated to form one complete ... -
Development of a software-based monitoring and information system for industrial telemetry applications
Prinsloo, J.; Mathews, M.; Du Plessis, J.; Vosloo, J. (Stellenbosch Univ, 2019)Industry stands to benefit from adopting Internet of Things (IoT) practices. However, reliability and quality of service are of the utmost importance. Challenges such as intermittent connectivity in wide-area wireless ... -
Evaluating complex mine ventilation operational changes through simulations
Nel, Andries J.H.; Vosloo, Jan C.; Mathews, Marc J. (Univ Cape Town, 2018)Increasing the profitability of the mining industry is contingent on its ability to improve operational efficiency. Mine ventilation networks typically represent 25-50% of a mine’s energy consumption and, therefore, ... -
Evaluating the feasibility of the 12L tax incentive for energy-intensive industries
Campbell, K.; Booysen, W.; Vosloo, J.C. (Univ Stellenbosch, 2017)Section 12L of the South African Income Tax Act (12L) aims to incentivise businesses to become more energy-efficient. However, claiming this benefit is a complex process that can become difficult, time-consuming, and costly ... -
Financial model for energy efficiency projects in the mining industry
Nel, A.J.H.; Vosloo, J.C.; Mathews, M.J. (Elsevier, 2018)The impact of industrial EE projects have previously been understated by the omission of non-energy benefits (NEBs). As a result, several fruitful projects have not been implemented which could have dire consequences for ... -
Improving data management for environmental reporting in the gold mining industry
Janse van Rensburg, H.M.; Gous, A.G.S.; Vosloo, J.C.; Van Heerden, M. (Stellenbosch Univ, 2019)Environmental reporting is a realistic alternative for mines to prioritise operational changes in crucial environmental areas. Gold mines report to multiple platforms – i.e., integrated reporting. All these platforms ... -
Integrated energy optimisation for the cement industry: a case study perspective
Swanepoel, Jan Adriaan; Mathews, Edward Henry; Vosloo, Jan; Liebenberg, Leon (Elsevier, 2014)Energy costs play a major role in the cement production process. As much as 60% of total cost is allocated to energy and 18% to the consumption of electrical energy. Historically, energy cost savings were achieved by ... -
Results and prospects of applying an ISO 50001 based reporting system on a cement plant
Pelser, Wiehan A.; Vosloo, Jan C.; Mathews, Marc J. (Elsevier, 2018)The cement industry plays an important role in global development and makes up a sizable portion of global energy consumption. Increased competition places strain on the oversupplied market, creating the need to improve ... -
Structuring uncertainty management for energy savings calculations
Johnson, K.A.; Hamer, W.; Vosloo, J.C. (Stellenbosch Univ, 2019)South Africa has committed itself to reducing its greenhouse gas emissions. A key strategy to minimise the greenhouse gas intensity involves using incentivised energy efficiency initiatives. In South Africa, one of these ... -
Towards industry 4.0: a roadmap for the South African heavy industry sector
Prinsloo, J.; Vosloo, J.C.; Mathews, E.H. (Stellenbosch Univ, 2019)The rapid growth and expansion of the Internet, as well as technical advances in the area of sensor technology, allow for the interconnection of physical objects for the purpose of achieving collective goals, which paves ... -
Using big data for insights into sustainable energy consumption in industrial and mining sectors
Herman, Jacobus; Herman, Hendrik; Mathews, Marc John; Vosloo, Jan Corné (Elsevier, 2018)Human activities related to the production and consumption of energy are negatively impacting the environment and need to be addressed by focusing on cleaner production. With this perspective, this study investigates ...
