SURFACE DRILLING Epiroc’s new generation SmartROC D65 DTH rig at an iron ore mine in Sweden SmartROC D65 DTH crawler drill rig that has been on the market for nine years and which the company says has become the market standard in its class of rigs. “Customers are looking forward to the new generation SmartROC D65 which has been tested with the latest technology at an iron ore mine in northern Sweden,” says Mattias Hjerpe, Product Manager. The rig was developed both as the result of planned development of a new SmartROC D65 within Epiroc but also from customer feedback and requests. Hjerpe adds: “The new SmartROC D65 is intelligent and is loaded with smart features such as automated drilling and rod handling. In addition, a new modern control system makes it simple to further develop automated functionality. One new functionality already developed is the AutoFeed Fold. With one touch functionality, the feed will fold for tramming or position for drilling. Yet another new feature is a friendly user interface with 15 in touch screen which will, for example, present live measure while drilling information.” The new drill also has a lower fuel consumption thanks to a more effective hydraulic system (300 litres less hydraulic oil). Increased productivity is brought by 8 m of pipes (previous drill had 6 m) meaning users can drill a 16 m production hole with only one pipe addition which saves a lot of time. The rig has also been designed to be ready for more forthcoming automation features soon to be released hence the description of it having been future proofed. Including the machine being tested in Sweden, several of the next generation SmartROC D65 rigs are understood to have been built, and are ready to be shipped to mining customers in Australia. New blasthole options All of the blasthole market leaders – Caterpillar, Sandvik, Epiroc and Komatsu have been launching new and ever more advanced blasthole rig models. The new Cat ® MD6200 rotary blasthole drill has flexibility at its core; being designed as a production drill with the flexibility to do pre-split drilling. And, all of this is in a package that is Caterpillar’s most transportable rotary drill yet. The MD6200 can perform rotary or DTH drilling in single-pass or multi-pass modes and can drill holes of 127 mm to 200 mm (5-7.87 in) in diameter. It can drill at a negative angle up to 15°, which enables matching the slope of the highwall for pre-split drilling. This results in cleaner highwalls with less waste material going to downstream operations, according to Cat. For traditional production drilling, the mast can tilt from vertical out to 30°, while the operator can adjust the mast angle in increments of 5° from the touch screen in the cab — with no special setup required. The MD6200 can be transported over the road with the mast on, so can roll onto a truck when it’s time to move to another site. The new drill also has the smallest shipping envelope of any drill in its class, says Cat. In some configurations, parts outside the shipping envelope can be removed without the use of lifting tools, allowing two people to prepare it by hand for shipping.
