Industry intelligence [4] MINING MIRROR JANUARY 2018 The big world beckons for Master Drilling One of Master Drilling’s raisebore drilling machines. The Fochville-based company is expanding its operations in India and Australia. HARMONY THROWS WEIGHT BEHIND ROCK ENGINEERING In June 2013, the University of Pretoria (UP) established a Rock Engineering Chair in the UP’s Mining Engineering Department. The initial aim was to conduct research on specific rock engineering issues, to provide a safer working environment in deep level hard rock mines. To facilitate this research, Harmony Gold Mining provided financial support required for the initial research period between 2014 and 2016. According to Navin Singh, the mining and minerals resources manager of the Council for Scientific and Industrial Research (CSIR), the technical challenges to mines today are even more severe, compounded by economic constraints and the increasing cost of labour. “These concerns highlight the need for renewed research in the mining industry as expressed in the creation of a Mining Resilience Research Centre (MRRC) at the University of Pretoria. The MRRC is an active participant in the South African Mining Extraction Research, Development and Innovation (SAMERDI) strategy managed by the CSIR,” says Singh. Universities, the industry and government work collaboratively to research critical issues within the mining industry – collectively called SAMERDI. The aim is to develop technological solutions to improve safety and productivity to reduce costs and extend the life of mines and their benefit to communities. In the process, mechanisation and non-explosive face advance methods are two of the thematic areas highlighted for research. In both these areas of research, the increase in advance rates to improve productivity are critical. The impact of substantial advance rates (continuous mining) on the safety of personnel within the working places, due to the perceived impact of seismic activity, could be significant. “The importance of this work in the current and future hard rock mining environment in the South African mining industry – and to ensure safer, deep level mining – has propelled Harmony to extend their financial support for this research to the end of 2019 by R5-million. This support allows the research to calibrate the developed software with actual underground closure and seismic behaviour at selected Harmony operations,” says Peter Steenkamp, CEO of Harmony. South African-based Master Drilling is increasing its global footprint. The drilling services company recently announced that it will support Indian diversified miners Vedanta, listed on the London Stock Exchange. One of Vedanta’s operations, Hindustan Zinc, has contracted Master Drilling to do the raisebore drilling work and the initial contract is worth about USD6-million. In Australia, a large raisebore machine will be contracted out to an underground mining contractor on a gold project. The rental contract, the first such agreement which sees Master Drilling supply the machine without manpower, will run for an initial period of one year. “These two deals mark our entry into India and Australia which are two new geographies for Master Drilling. Both contracts are also in commodities targeted in our strategic plan, that is gold and zinc. We will continue to explore new geographies and further diversify our contracting approach to maximise the utilisation rates of our machines and further develop our global footprint,” says Danie Pretorius, CEO at Master Drilling. Pretorius adds that both contracts relate to underground ventilation works to be completed over the next two years. Mines must embrace digital revolution The digital revolution could help address the operational complexities mining operations have been grappling with for years, according to Wilhelm Swart, vice president for mining, minerals and metals Africa Business at Schneider Electric. “The digital revolution could help address this complexity and provide a competitive advantage, yet many companies have not leveraged the latest technologies available to make their operations more efficient,” says Swart. Schneider Electric recently announced ‘EcoStruxure for Mining, Minerals and Metals’, a new system architecture and platform that leverages innovative digital technologies and the Industrial Internet of Things (IIoT). The new system allows companies to seamlessly connect, collect, analyse and act on data in real time to improve safety, efficiency, reliability and sustainability. “EcoStruxure is not just another platform limited to asset performance analytics. It is a complete set of digital technologies and applications that can improve the performance of the entire organisation, from people to operations to supply chain,” concludes Swart.
