Compared to manual methods, Joe Palmer, Senior Blasting Technician, with 17 years of service at Luck Stone, says the rig provides more accurate measurements on the face, in designing shots, and while drilling to hit the precise azimuth needed. Between the use of drones, digital photos, computer-planning and GPS guided drilling, the whole process has been transformed to fit on a thumb drive. George Feild, Blasting Manager, with 24 years of service, says the system “makes the job easier by giving the blaster quite a bit of confidence” thanks to the precision in lining up the shot. David Harper, Pit Lead, also with 24 years of service, adds that the HNS helps execute accurate burdens on the face. Roger Stewart, Drill Operator with Northern Virginia Drilling, puts it simply: “Other rigs just don’t compare.” The Epiroc SmartROC D60 has a trickle-down effect for the entire operation. Griffin Lober, Pit Loader Operator, reports that he has seen significantly more consistent diggability, less oversize material, reduced cycle times, better truck flow, higher production, smoother treatment on equipment, and an easier and more productive day overall.
As the market marches toward more automated, autonomous and smart equipment, Scott and Shawn Miller, brothers and co-owners of Northern Virginia Drilling, double down on the need for technology, not just in quarries and mines, but across public and private construction. Thanks to the Spotsylvania results, the Epiroc SmartROC drills with HNS are now capturing valuable measure-while-drilling (MWD) data that will enable Luck Stone to do further analysis and continuously improve their drilling and blasting processes. In fact, Luck Stone is already making plans for taking Epiroc-powered machines into more hazardous high-wall conditions and difficult blast zones thanks to the MWD data, which includes multiple readings in every drilled hole, capturing the penetration rate of the drill bit, feed pressure, rotation pressure, flushing air pressure, and calculated rock hardness. When 4 p.m. arrives, the hum of the drill slows and then stops. Stewart powers off the Rig Control System, performs his safety checks and climbs out of the climate-controlled cab (one of his favorite features, he added laughingly). The magic winds down, ready to rest and start again the next day.
