PROVEN PRODUCTS AND SYSTEMS FOR DUST MITIGATION While it has been proven to increase efficiency, the rig also reflects Joy's "safe- ty-driven core philosophy," Collins said. The rig's auto bit changer function is one example. "This was designed to allow for the highest levels of safety with tasks that are typically manually intensive: lifting and threading bits," he said. "The auto bit changer allows the operator to simply touch a button to exchange a used bit with a new bit in less than 10 minutes — with- out leaving the cab or, if operating the ma- chine in autonomous mode, without board- ing the machine. This revolutionary feature will allow more time in-the-hole drilling." Similarly, the one-touch Auto Pipe Changer function automatically exchang- es or adds drill pipe into the drill string. "Typically, this would be a process-inten- sive procedure that can introduce chal- lenges with cross threading," Collins said. The goal here is to offer efficiencies with consumable management, leading to lon- ger component life and easier operation through automation." Last year, Joy told E&MJ it had field tested units at North American copper and iron ore operations. 1 Controller, 3 Drills Sandvik announced at MINExpo its Au- toMine Surface Drilling automation solu- tion system had been field-proven on the DR461i rotary blasthole drill. The "sys- tem improves machine performance and efficiency by offering automated features that enhance operator comfort and capa- bility," Tab Siegrist, global product line manager, surface drilling, said. "AutoM- ine provides reduced cost, improved safe- ty and improved consistency to the high performance of the DR461i." The rig drills an 8.5- to 12.25-in.-di- ameter hole (216-311 mm) with a maxi- mum single-pass depth of 102 ft (31 m). The maximum multipass depth is 246 ft (75 m). It is reportedly an evolution-
