Underground improvement is a crucial facet of contemporary mining operations, permitting for the entry and extraction of useful assets buried deep beneath the Earth’s floor.
In contrast to open-pit mining, which entails eradicating massive volumes of overlying rock, underground mining targets ore our bodies which can be too deep or in any other case unsuitable for floor extraction.
The method begins with improvement mining, the place drill rigs create drifts or declines to entry the ore geometries. These tunnels type the “roads” via which miners, gear, and supplies journey.
Watch a video information to underground improvement beneath.
Improvement mining is usually carried out earlier than precise ore extraction begins and serves as a basis for the whole mining operation.
By means of a choreographed sequence, a fleet of various gear enter the drift and execute particular duties: Jumbos handle ground-support and development, whereas loaders are tasked with eradicating blasted rock. Ancillary autos are used for providers and explosives administration.
Security is paramount in underground mining. Engineers and geologists work collectively to evaluate floor situations, monitor for potential hazards like fuel accumulation, and guarantee structural integrity.
Superior know-how, reminiscent of remote-operated equipment and real-time information monitoring, additionally helps enhance each employee security and operational effectivity.
Underground mining performs an important function in offering the uncooked supplies that drive industries from electronics to development. Because the demand for sure minerals will increase and deposits close to the floor develop into exhausted, underground improvement mining is more and more a significant a part of the worldwide mining panorama.
Options for underground mining challenges
As mines push deeper beneath the floor for deposits, the necessity for higher communication and collaboration will increase. A mine’s capacity to digitise processes and react to workflow modifications in actual time means operations could be optimised and property and fleet managed extra safely.
As a life-of-mine know-how accomplice, Hexagon gives options to deal with underground challenges. For instance, Hexagon MinePlan software program for visualization, evaluation and analysis is utilized by mines everywhere in the world for design, modelling and reserve calculations.
MinePlan has its origins in software program developed greater than 50 years in the past when computer systems had been first utilized to unravel advanced geology and engineering challenges for open pit and underground mines. The software program brings readability and insights to the advanced enterprise of remodeling a useful resource right into a secure and sustainable operation whereas additionally enabling efficient capital funding for digitalisation, automation and electrification to scale back impacts on individuals and the planet.
Hexagon merchandise for underground fleet administration, drilling and manufacturing optimisation, security and autonomy are summarised beneath.
Hexagon UG Pro is an built-in tablet-hardware and software program utility. It manages fleet gear and optimises production-time utilisation in actual time when related to supported underground communications techniques. It tracks areas and motion, and screens task-level actions, modifying miner and machine workflows in actual time because the mine develops and advances.
Hexagon Development Optimiser is an OEM-agnostic alignment system that equips every growth with a detachable, wi-fi sensor referred to as the Optibox. Paired with a ruggedised pill and Hexagon’s CORE Internet platform, the system offers real-time alignment suggestions and shift-to-shift drill efficiency insights. It permits operators of all expertise ranges to drill precisely to design—delivering extra constant blast outcomes for each reduce. The result’s improved fragmentation, diminished overbreak, and elevated fee of advance.
Hexagon Production Optimiser is designed for longhole drilling and makes use of an analogous alignment and suggestions mannequin to Improvement Optimiser that’s tailor-made for long-hole drilling functions. By offering drillers with real-time collar accuracy at every gap, Manufacturing Optimiser helps tighter drilling, diminished dilution, and improved stope form—delivering downstream advantages to fragmentation, restoration, and mill efficiency.
Collectively, Improvement Optimiser and Manufacturing Optimiser characterize a unified, system-agnostic strategy to underground drilling optimisation. The success of this strategy in constructing a digital drilling basis is featured within the following two articles:
Hexagon Operator Alertness System employs superior sensor know-how and machine-learning algorithms to actively monitor operators’ alertness ranges. When indicators of distraction, drowsiness, or microsleeps are detected, operators obtain real-time notifications, offering an important layer of safety throughout their demanding 12-hour shifts. Deployed at MMG’s Rosebery underground mine, OAS led to an 81% discount in extreme fatigue occasions.
Hexagon Collision Avoidance System is the business’s main collision avoidance resolution for shielding drivers and gear above and beneath floor, offering 360-degree NLOS (non-line-of-sight propagation) operator consciousness for autos, property and operators – via snow, rain, fog and mud. CAS can now be enhanced by integrating Hexagon TeleOp for an additional layer of safety. Using onboard cameras and sensors, TeleOp is a digital command chair for the truck operator, enabling secure navigation of autos from kilometres away.
Hexagon’s acquisition of radar and real-time location techniques chief, indurad, will additional assist to mitigate collision dangers in underground mines.
Conclusion
Hexagon know-how paired with coaching and course of change provide a strong useful resource for underground mines trying to enhance effectivity, scale back rework, and strengthen security outcomes. New developments in automation, planning integration, and alignment analytics are underway. By digitising, connecting, and optimising underground operations, mines can keep away from unplanned downtime and luxuriate in relative peace of thoughts in an unsure enterprise.
All through 2025 we’ll be running a blog concerning the challenges dealing with the mining business. Drawing upon insights from thought leaders in our buyer neighborhood and from inside Hexagon, we’ll share how trusted partnerships and confirmed know-how are addressing these challenges, serving to to enhance security and reduce prices whereas balancing the calls for of productiveness and sustainability.
