AXXIS’s state-of-the-art blast and design software enables complex timing designs for vibration control, improved fragmentation, heave and better final walls.
driving the transition to a more sustainable economy.
Enhancing BLASTMAP A cornerstone technology of quality blasting is great blast-planning software. BME’s well-established BLASTMAP blast- planning tool has been enhanced with a powerful burden relief timing module. This gives blasters finer control of shape and movement of the blasted rock muckpile. It’s a critical enabler for the company’s leading AXXIS electronic
stacked higher, so tighter burden relief times are required.
The enhancements to BLASTMAP integrate with BME’s AXXIS system. This allows blast technicians to program a detonator with the desired time delay. It integrates with BME’s XPLOLOG system for blast engineers and management to view, capture and sync drill and blast data to a cloud database for real-time access to preparation progress on the blast block. This data informs decisions critical for planning and managing block operations.

initiation system, and crucial to optimising efficiency of the excavation fleet. If a mine uses a loader and truck fleet, the blasted rock must be laid out lower. To achieve this, longer burden relief times are needed. A truck and shovel configuration, on the other hand, requires the muckpile to be
46 BLASTMAP capabilities
BLASTMAP capabilities include initiation timing design, initiation sequence simulation, blasthole loading design, vibration and blasted rock range predictions, and fragmentation distribution predictions.
Initiation timing design enables design of blast initiation sequences and facilitates programming the AXXIS system. The initiation sequence simulation allows the user to check for correct hole firing sequences and pick up potential out-of- sequence firings. The blasthole loading design module – covering the explosive load, booster and initiation system – is capable of designing decked hole loading. For fragmentation prediction, one of three equations are available. Site-specific or general rock properties can be entered into an editable rock properties database and fragmentation models can be calibrated with data from physical fragmentation distribution measurements.
Fragmentation and vibration control
Fragmentation distribution is vital to quality blasting, and critical for mining machine productivity when loading and hauling. The optimisation of fragmentation distribution in the crushing and milling circuit improves throughput and recovery. The vibration prediction tool generates a predictive isomap of vibration levels around the blast, ensuring blast vibrations
