Leader in proximity detection systems, Booyco Electronics, is equipping 19 mechanised mining machines with its latest Booyco CXS proximity detection solution to enhance safety during the development phase of underground operations at Namibia’s largest gold mine.
According to Anton Lourens, Booyco Electronics CEO, the order was placed by long-time customer Murray & Roberts Cementation, who will be establishing the underground stoping horizon for the Wolfshag zone of B2Gold’s Otjikoto mine.
The contract also includes sensing devices for 120 personnel who will work underground on the operation. The sensing devices are placed in each employee’s cap lamp to provide a proximity alarm.
“Our equipment will help achieve the highest level of safety on this project by mitigating the risk of collisions between pedestrians and vehicles, and between vehicles,” says Lourens. “The installation of our CXS units is in line with the commitment by the mine and the contractor to zero harm in the workplace.”
The Cementation Lewcor JV contract will take 28 months. Lewcor Mining is a Namibian company with extensive mining experience in that country. The contract includes a decline of 5.0 m wide by 5.5 m high being driven to the orebody from a portal in one of Otjikoto’s depleted open pits. The operation will be highly mechanised, with equipment including drill rigs, dump trucks, load-haul dumpers and utility vehicles, as well as shotcreting and ancillary equipment.
Lourens highlights that Booyco Electronics’ latest generation CXS system being used on the project is a comprehensive and integrated proximity detection solution. The technology takes a step beyond being just a warning system, to becoming a true collision avoidance system.
“The CXS system on this project will deliver Level 7 and Level 8 capabilities in terms of the Earth Moving Equipment Safety Roundtable (EMESRT) safety levels, and can also accommodate Level 9,” he says. “Although there is not yet a legal requirement for collision avoidance systems in Namibia, our customer and the mine adopt a global best practice approach to all aspects of safety in mining operations.”
The mine is located more than 300 km north of Windhoek, so it was important that the equipment should be robust and reliable to ensure maximum uptime, Lourens adds.
“To ensure that the equipment performs optimally, we have trained the customers’ artisans on how to look after it,” Lourens says. “A qualified serviceman from Booyco Electronics will also visit the site regularly to audit performance, assess the equipment and conduct any necessary maintenance.”
A pioneer of proximity detection systems in South Africa, Booyco Electronics’ home-grown technology has seen wide take-up in underground mining operations – both hard rock and coal – as well as in the opencast environment, and in plants and warehouses.
Since the company was established in 2006, safety regulations have changed significantly and Lourens notes that one of the strengths of Booyco Electronics’ technology is that it has constantly evolved to meet the needs of the industry.
The company now has a footprint extending to over 100 mining customers in South Africa, and the Otjikoto project in Namibia is part of its gradual expansion into other countries in Southern Africa. Lourens highlights that collision avoidance systems are likely to become mandatory in a growing number of neighbouring states as these countries usually follow South African regulations. Major miners are also driving change through the globally recognised EMESRT guidelines.
“The International Council on Mining and Metals is an important stakeholder in this process,” Lourens says. “According to the ICMM, transport and mobile equipment accidents were the highest cause of fatalities at its members’ operations in 2018, accounting for 30% of fatalities.”For more information visit: www.booyco-electronics.com
