More Tonnage Anyone?

By reducing survey time and eliminating block scheduling delays, this will

increase mucking time per day to ensure daily targets.


As we look along the value chain where can we find opportunity to improve, we optimize and/or transform the ability to increase the tons per day targets. A major factor in the tons per day target is the total available mucking time. Increase the amount of time scoops are loading means directly increasing the amount of material moved. The challenge is to find the points in the value chain were mucking is suspended and determine if they can be reduced or removed.

Two key points in the process to create opportunity; stope assessments and block scheduling. When traditional CMS is used to assess a stope volume the process can take 60 minutes or more. How might we reduce this?

Stope development is often affected by block scheduling to backfill adjacent completed stopes. Back fill estimates that produce too much error delay block scheduling which can delay stope development and mucking time. How might we reduce block

scheduling delays?


Step 1 – Develop in motion LiDAR utility that creates access to areas that today are inaccessible to traditional CMS. Integrating the latest LiDAR, drone and IMU technology allows for the creation of point cloud and 3D model data.

Step 2 – Maneuver LiDAR scanning technology using drones (SafeSight DB2) and droids (SafeScan Ground) to allow for deeper access into the stope. Why drones and droids? With over 50+ missions under our belt and 100 scans we recognize that there will always be reasons when flight is not a fit. In these instances, our ground game - LiDAR in motion tools, SafeScanner and SafeScan Ground ensures that we gather the data.

This Innovation ensures full access to the target environment, scans 600,000 points per second and can be executed in less that 20 minutes. This is less that half the time of a traditional CMS tool. Point cloud data is produced on board in under 2 hours.


Our field work has given us the following insight: using LiDAR enabled ground and UAV solutions reduce the time surveying and increases our mucking time. LiDAR based scans remove shadow and estimation error introduced by traditional CMS and fill volumes are more accurate. Correct paste calculations remove block scheduling delays which creates more mucking time opportunity.
