MinePortal Adds Auto Void Detection to List of Solutions Increasing Safety at the Mine

auto void detection in old underground workings

Mining through old underground workings is dangerous when voids in the subsurface go undetected. Relying on manual logging from a drill operator to mark one of these holes is a time-consuming process. It leads to inconsistent and slow reporting resulting in the important geology information not shared with the right personal at the right time.  Mine sites significantly improve safety if teams are immediately alerted to the presence and properties of voids and are able to alter their plans accordingly.

Leveraging MinePortal's ability to rapidly process drilling data and automate detections of geological features, we increase safety at the mine. This is a step-change improvement for operations that have added precautionary measures to their open pit operations where old underground workings are present. These mine sites reduce the risk and costs associated with hand-written comments thanks to real-time alerts when it detects a void during drilling.

Further adding confidence to clients’ orebody knowledge, DataCloud sets up real-time alerts and daily report for clients that maps the presence  and properties of these voids. The information is shared across all teams from supervisors to engineers and can be visualized by everyone in 3D. Mine site operators now have the tools necessary to improve safety and productivity from planning to blasting.

Value of Void Detection

SAFETY: unknowingly walking, driving, or operating over an undetected void rather than solid ground is a huge risk

BLASTING: D&B teams adapt plans to use the proper amount of explosives to maintain confinement, to prevent misfires, and to meet fragmentation requirements

GRADE: you can expect high grade near the void as this is where older generations of miners would have been following profitable ore

Manually processing your blast hole drill’s rate of penetration (ROP) is not easy nor consistent enough to increase assurance and safety. Using software to reconcile data from your drilling system and manual logs leads to highly accurate and timely detections. Cross analyzing insights to other data points eliminates noise from anomalies.

MinePortal filters outliers, like preconditioning, and matches the drill's response to a legitimate void versus the drill's response to simply a high ROP. Furthering confidence, we apply machine learning to the data to continually improve identification of voids, tunnels, stopes, and veins.

Benefits of Automating Void Detection

INCREASE SAFETY: alerts and daily reports of void detection helps teams decide how to adapt

SAVE TIME: takes away the responsibility of manually entering comments into the drill system by how the blast hole drill is behaving and processes data faster

SAVE COST: reduces time on the job and costs of efforts to avoid safety risks

OPTIMIZE: creates  a foundation for data-driven decision making and shared rock knowledge across teams

Easily Use This in Your Workflow

MinePortal gives everyone seamless access to all location-based information related to the mine to mill process. Your single source of truth to your geology is available fast and securely with a simple browser login backed by Microsoft Azure. This improves collaboration by allowing each operation to work with others towards a common goal and to track progress as a team. Engineering time that is currently spent on data manipulation can now be focused on analysis and optimization.
