Epiroc Donates Rock Drill to Colorado School of Mines
COP 1238K Rock Drill to Update Testing Equipment at EMI
Epiroc, a manufacturer for the mining and infrastructure industries, has donated a COP 1238K rock drill to the Excavation Engineering and Earth Mechanics Institute (EMI) at the Colorado School of Mines. The COP 1238K hydraulic rock drill for tunneling and drifting applications updates testing equipment at EMI, the largest independent rock drilling and excavation research facility in the world.
“Epiroc has tremendous appreciation for and confidence in the work that EMI does,” says Shawn Cheney, Epiroc business line manager – rock drilling tools. “We recently partnered with EMI on a project related to the cutting technology on our Mobile Miner. We’re honored to donate equipment that will help EMI continue to serve as a valuable resource for the mining and civil underground construction industries.”
Located in Golden, Colorado, the Colorado School of Mines is known globally for its unique expertise in topics related to earth, energy and the environment. EMI was established in 1974 to enhance education and research in the field of excavation technology for mining and civil underground construction, and the Institute has become one of the world’s leading research facilities.
Over its 45 years of existence, EMI has developed a suite of physical property tests, cutter and cutterhead evaluation procedures for performance prediction, project costing, and design of mechanical rock excavation tools for all types of mechanical excavators in mining, civil underground construction, and microtunneling. The developed test procedures and performance/cost prediction models have been validated with extensive field data from excavation and drilling projects around the world.
The rock drill donation came about through collaboration between Cheney and Jamal Rostami, Ph.D., PE, director of the Earth Mechanics Institute. A member of the EMI industrial advisory board, Cheney facilitated the donation of the COP 1238K to replace EMI’s decades-old testing drill, with the new test cell installation completed in February 2019.
“We greatly appreciate the generosity of Epiroc,” Rostami says. “The COP 1238K rock drill donation gives EMI the opportunity to perform full-scale testing using the latest in rock drilling technology. This test unit will drive research that contributes to more efficient and safer drilling operations in the industries we support.”
Developed to maximize impact power while optimizing durability in underground applications, the COP 1238K is optimized at hole diameters from 2 to 3½ inches and has a power rating of 12kW. It features a built-in reflex damper that contributes to improved drill steel economy and reduces wear on the rock drill, feed and boom. A powerful stepless variable and reversible rotation motor provides high torque and excellent speed control. In addition, a long, slender piston matched to the drill steel delivers optimal impact power without damaging the drill steel.
