Cradle to grave Technology to extend mine life This means that a higher power conversion can be achieved by using customised solutions that optimise power delivery and reduce the total cost of ownership. In November 2017, Eaton undertook a large-scale project to deliver medium voltage (MV) switchgear consisting of 14 panel UX switchboards for Northam Platinum Mining. The project replaced three ageing and redundant substations consisting of a four-panel, seven-panel and three-panel switchboard. The new panels minimised downtime, increased plant efficiency and improved safety of personnel. Mining operations can effectively improve productivity by ensuring machines run more reliably around the clock, without fail. If there is a breakdown, these facilities are serviced quicker, using predictable methods and using parts that are readily available to keep downtime to a minimum. New video surveillance tools detect process and security problems before they occur, and fire detection and access control systems ensure assets are safe and secure. With safety being a key concern in mining, particularly in South Africa where there is a high concentration of deep level mining, modern technology helps ensures that mines The South African mining industry recently marked 15 consecutive months of declines in production, reflecting a broader decline in mining activity that has resulted in a 30% loss of employment since 2009. While it is inevitable that South Africa is making a transition from a resource-based economy to a knowledge economy that’s driven by digital technology, mining is an important contributor to the economy and the country remains a top global producer of a diverse range of minerals. However, declining ore grades are putting pressure on every aspect of mining operations, resulting in an urgent need for owners, operators and management teams to closely manage capital and improve cost per ton. With energy costs consuming up to 15% of a mine’s operating budget, operators need to find ways of managing power more efficiently. Despite the demand for uninterrupted uptime, managers are forced to manage and upgrade plants that need more reliable products, people and processes than ever before. In order to extend the life of mines, preserve profit margins and slow job attrition, managers can employ a variety of modern power management solutions to deliver holistic power, fuel and productivity efficiency. can protect their employees and give operators safe, reliable control in harsh environments and changing conditions. Also, automated machinery is more fuel efficient, reducing emissions across any fleet and minimising environmental impact. An integrated power management system helps to reduce the environmental footprint using components that better manage fluid transfer, wastewater reuse and water filtration and deliver energy efficiency. This serves to reduce energy consumed (and produced) per ton, which offers direct environmental benefits in a world where carbon reports and impact statements drive build and operate decisions. Eaton helps customers to be more energy- efficient through a portfolio of solutions dedicated to enabling sustainable businesses and extend the lifecycle of long-term businesses such as mines. In a declining mining sector, every bit of saving counts towards extending the lifespan of mines and stems the tide of job losses. With the various challenges to South Africa’s electricity grid, better power management will also contribute to reducing power wastage more safely and with a much lower impact on the environment. 3D scanning improves accuracy Using three-dimensional (3D) scanning technology during on-site assessments has enhanced the levels of accuracy and as a result minimised rework costs in design and manufacturing, and significantly reduced downtime during installation. This is according to Mark Baller, managing director at Weba Chute Systems and Solutions, a local manufacturer of custom transfer points and chute systems. “Implementing 3D scanning technology to our capabilities two years ago enabled our on-site technical teams to obtain accurate measurements from a safe distance and allows us to inspect and survey large infrastructure in detail,” says Baller. “The technology allows us to consider all elements in existing infrastructure and this plays an important role when replacing transfer points or chutes as we are able to create an accurate preliminary design and costing in the early feasibility stages of a project,” he adds. allows us to consider all elements in existing infrastructure.
