For many years, large-diameter blasthole drilling has relied on rotary instruments or pneumatic DTH techniques. Each approaches undergo vital power losses between the facility supply and the rock face – particularly when looking for increased penetration charges.
Mincon says its new Hybrid Affect Expertise™ (HIT), previously known as Greenhammer, replaces compressed air with hydraulic power, transferring energy to the bit extra instantly with decreased power loss. “The result’s a confirmed mixture of upper penetration charges via dramatically improved power effectivity and considerably decreased gas utilization, which collectively cut back whole drilling price (TDC).”
It says it’s the fruits of R&D relationship again to 2013 and builds on Mincon’s pioneering work in growing high-efficiency air-powered rock drilling options for mining, development, and renewable power. “That in depth experience, mixed with Mincon’s revolutionary spirit, helped to refine and develop this patented new hydraulic DTH know-how throughout discipline testing in demanding situations, from Australia to Arizona.”
In in depth mine testing, drilling 10⅝” (270 mm) gap measurement on an tailored Epiroc PV271 drill rig, at an Arizona copper mine, a HIT-powered system demonstrated vital will increase in drilling velocity and reductions in gas utilization per foot drilled in comparison with the mine’s present rotary drilling technique. These velocity beneficial properties and gas financial savings mixed to considerably cut back the whole drilling price (TDC) of drilling operations, together with a corresponding discount in CO2 emissions, supporting decarbonisation objectives with out compromising manufacturing.
Beneath a three-year unique collaboration, Mincon and Epiroc will likely be integrating Hybrid Affect Expertise™ on Epiroc’s rotary blasthole drill rigs. Mincon’s hydraulic DTH experience and Epiroc’s market-leading Pit Viper single-pass drill rigs will carry this know-how into on a regular basis manufacturing throughout world websites.
The know-how is designed for large-diameter single-pass blast gap drilling in medium to arduous rock situations for open-pit mining functions. Mincon and Epiroc plan additional pilot deployments whereas progressing system integration and manufacturing. They’re working collectively to combine HIT into Epiroc blasthole rigs, combining Mincon tooling with Epiroc {hardware}, software program, and management techniques to ship a production-ready hydraulic DTH answer. Further technical particulars and availability timelines will likely be shared within the coming months.
“HIT has been designed to ship a step change in drilling efficiency for the mining trade. The long-term future demand for mined minerals, together with world decarbonisation objectives, would require techniques that provide a lot increased productiveness whereas reducing carbon emissions. We’re extremely proud to carry this know-how, in collaboration with Epiroc, to the mining market as a showcase of our innovation and collective capabilities,” mentioned Joe Purcell, CEO, Mincon Group.
“Epiroc is happy to embark on this long-term collaboration journey with Mincon and mix our superior drilling applied sciences to lift the effectivity and efficiency within the massive blasthole drilling actions of our clients and set a brand new commonplace within the trade. We’re proud to have the ability to help the mining trade with a brand new, subsequent degree, sustainable drilling answer that can help the mining trade to succeed in their environmental objectives,” mentioned Martin Hjerpe, President, Epiroc Instruments Division.
