New features enhance the value of Aegis drill and blast tools to aid underground blast design and analysis.
Maptek began selling Aegis in 2016 to complement existing underground design tools. New functionality in this easy-to-use underground drill and blast design and analysis product provides further value for operations.
Advanced Cost Modelling in Aegis Analyzer allows users to prepare a detailed model to estimate the total cost of a stope, including fixed costs of preparation, drilling, explosives and mucking.
The flexibility of the model allows costs to be determined based on calculated quantities, such as number of holes, metres of drilling or kilograms of explosives. Cost models can then be applied to scenarios to calculate the total cost.
When combined with the unique Aegis break prediction abilities, and forthcoming fragmentation functionality, Advanced Cost Modelling will allow blasting engineers to compare different scenarios. For example, what are the real cost savings of switching to a cheaper explosives product?
Given that changing explosives might also require a change in drillhole diameter, spacing, priming, loading procedure or any number of other variables with associated costs, accurate modelling is necessary to determine the true cost difference to achieve the same blast results.
Break Analysis functionality in Aegis will give blasting engineers advanced tools to analyse and improve blasting practices. Along with blast monitoring, which will feed into the analysis, these tools will help operations to reduce overbreak and underbreak.
The full 3D break analysis will be a key part of Aegis Analyzer, while a simpler 2D analysis is being added to the already rich feature set in Aegis Designer.
A Fragmentation prediction algorithm will in the future be incorporated into break analysis, allowing further optimisation of the results of underground blasts.
Users will also be able to calculate the estimated Blast Vibration attenuation resulting from a blast, at any point in space. Mines will be able to adhere to vibration restrictions more dynamically than using the conventional method of a simple cap on the weight of explosives per delay.
A new Lateral Development module will apply advanced user-friendly long hole drill and blast tools. Users will be able to model face rounds in 3D and adjust the positioning and distribution of holes both at the face and at any point in the round.
Blasts can be modelled using the Break Analysis algorithms to estimate the extent of break and damage. The predicted excavation can then be reconciled to a survey.
Aegis is more than just a drill and blast design tool – it is a complete underground blast planning, analysis and optimisation solution incorporating the latest innovations in explosives engineering.
Aegis is available in English, Spanish and Russian.
