Murray & Roberts Cementation Zambia has been awarded the shaft sinking and equipping of the Synclinorium shaft for Mopani Copper Mines in Kitwe, Zambia. The new shaft is expected to add about 25 years to the life of the Nkana copper and cobalt mine near Kitwe. The main shaft, which will be sunk to 1,200 m with a 7 m diameter, will be equipped as a rock hoisting shaft on this brownfields mine to service a new area under development. A 6 m diameter raisebored ventilation shaft will form part of the full project. By 2018 the new shaft will boost Nkana’s ore production from 3.4 Mt/y to 5.1 Mt/y. Mopani is an integrated copper and cobalt producer located in the Zambian Copperbelt. Mopani’s operations comprise four underground mines, a concentrator and a cobalt plant around the town of Kitwe and an underground mine, concentrator, smelter and refinery at Mufulira. Murray & Roberts Cementation offers a comprehensive range of capabilities and services covering the full spectrum of the mining value chain. The company has served the mining industry for more than a century and is a leader in shaft sinking, contract mining and raise-and shaftboring technology and services, with a strong track record of successful mine project delivery worldwide. Allan Widlake, Business Development Executive at Murray & Roberts Cementation, says that people remain Murray & Roberts Cementation’s most valuable asset and that the safety of employees and other site personnel working is not negotiable.“We maintain a business culture designed to keep safety constantly top-of-mind through the “Stop.Think” campaign, risk assessments, training, observation and coaching of employees to promote our Zero Harm objective,” he says. “Each person’s accountability and responsibility to ensure safety is a tenet of the company’s philosophy and our employees are consistently encouraged to ‘do it right, first time, safely’.”The organisation’s Business Management System actively drives safe business outcomes and Murray & Roberts Cementation’s 1st Choice Programme promotes the correct behaviours, values and principles that will ensure that this safety culture is grown from within.The company’s Bentley Park training facility near Carletonville, South Africa, provides a training service that produces skilled operators who can apply what they have learnt to ensure a safe outcome on site. The facility harnesses a highly successful combination of knowledge and hands-on skilling at a shaft mock-up on the campus, where real-life working conditions are simulated in as much detail as possible. This approach comprehensively supplements the facility’s computerised operation simulators.
The Centre for Excellence in Mining Innovation (CEMI) is hosting a second event at the CIM 2013 convention in Toronto, a forum on Ventilation On Demand (VOD). Please send your RSVP to Courtney Folz [email protected] CEMI is hosting an information and discussion forum on VOD. This no cost session is open to ventilation practitioners interested in advancing the adoption of VOD at their mines. It will be held Monday May 6, Metro Toronto Convention Centre, North Building, Room 201C, 2:00 – 5:00 PM and will include a presentation of findings, an introduction of VOD performance metrics and a round table discussion to determine industry priorities for faster and more effective adoption of VOD.The information and discussion forum will present the summary findings from CEMI’s 18 month CAF-VOD study sponsored by Vale, Xstrata Nickel, CANMET and Industry Canada. The study investigated two VOD system installations with the objective of quantifying the business case for VOD while collecting scientifically valid field data to assess the effects of VOD on the workplace. A significant CAF-VOD finding identified the potential for increased productive capacity that VOD provides in existing mines, improving the payback that can be realized from energy savings alone.CEMI is developing a collaborative program to pursue the next phase of VOD investigative work. The program will be focusing on determining and further quantifying the benefits that VOD can provide to improve ventilation effectiveness, energy intensity, design best practices and improved production capacity. VOD provides a potential paradigm shift affecting design and operation of our future mines.
