Technology and innovation Drilling up a storm The delivery of three Epiroc FlexiROC D65 surface drill rigs has bolstered Northern Cape company Booysen Bore Drilling’s total machine fleet significantly. According to Pieter Malan, general manager at Booysen Bore Drilling, the company now operates a fleet of 51 machines. Malan says the company purchased their first FlexiROC D65s in 2013. “This machine has now drilled in more than 500 000 300mm-diameter holes in the Northern Cape,” says Malan. Their fleet also includes a SmartROC D65 for blast-hole drilling, as well as a few CS14 and CS1500 core drilling machines. Epiroc evolved from the global split in January 2018 of Atlas Copco into two separate companies and comprises the Mining & Rock Excavation Technique business area and the Construction Tools division to focus on the mining and civil engineering sectors. The industrial businesses remain with Atlas Copco. Epiroc business line manager: Surface & Exploration Drilling (SED), Hedley Birnie, explains how the business partnership with Booysen Bore started: “In 1999, SED area sales manager for Atlas Copco, Cobus Engelbrecht, conducted the very first trial with a ROC L8 MK I test machine for Booysen Bore at Beeshoek manganese mine. The machine was the first drill rig capable of drilling at an angle, making it ideally suited for block drilling. Booysen Bore was so impressed with the ROC L8’s performance that they decided to keep the machine for blast-hole drilling on the mine and to systematically [38] MINING MIRROR JUNE 2018 replace all their non-Atlas Copco drill rigs at the end of their life cycle with ROC L8s.” When founded in 1977 by Hennie Booysen, Booysen Bore focused mainly on exploration drilling. In 1990, the family business expanded its services to blast-hole drilling and continued to grow into the successful business and major role player in the Northern Cape’s mining environment that it is today. Part of the Mogs (Mineral, Oil & Gas Services) Group, Booysen Bore’s offering includes down-the-hole (DTH), percussion, exploration, and core drilling, as well as in-pit de-watering drilling services. Operating with a staff of 430 from the Kuruman head office, supported by an office in Beeshoek under the auspices of Hennie’s son Hein as general manager and a facility in Kathu, the company is active mainly in the province’s iron ore and manganese mines, but also holds a sizable market share in the supply of drilling services to solar facilities in the region. Thirty-eight out of the total of 51 ROC L8, D60 and D65 machines are currently in operation. The Northern Cape area presents some of the most challenging conditions in the world. “We drill into some of the hardest rock in the world, with compressive strengths above 500MPa under extreme surface and weather conditions; these drilling machines take a huge hammering. “The Epiroc drill rigs give us up to 80% availability over many years of operation, and the machines lasts for more than 30 000 hours plus. In addition, the ROC boasts the lowest fuel A solid long-term business partnership.

So, as far as we are concerned, when it comes to technology, reliability, ease of operation, manoeuvrability, and fuel efficiency, the ROC machines are in a class of their own,” says Malan.
