Blast Design & Deviation
Blast design, borehole deviation surveys and post-blast measurement.
Design, drilled holes and results checked against each other on every blast.
Overview
A hole that drifts a few degrees changes the burden, the charge and the outcome. AltAmana combines blast design, borehole deviation measurement and fragmentation analysis in one loop, so crews can correct holes before charging and every design change is backed by measured site data. Results can feed WIRE, AltAmana's pit-to-profit data platform.
Supply
Survey results before charging [Confirm]. CSV and DXF export to WIRE and mine-planning systems.
Blast Design & Deviation range
| Product | Description | Output | Used for |
|---|---|---|---|
| Blast design (BLD-DES-201) | Pattern, timing and charge design. Designs for production, pre-split and trim blasts, built around fragmentation, wall-control and dilution targets. | Design file and charge plan | Production, pre-split and trim blasts |
| Deviation surveys (BLD-SRV-202) | Probe and gyro measurement of collar, dip and azimuth. Each hole is measured against design and shown as a 3D trace, with deviation percentage and collar error, so charges can be adjusted or holes redrilled before loading. | 3D hole traces, deviation %, collar error | Correcting holes before charging |
| Deviation tools (BLD-TLS-203) | Survey probes and gyros for in-house crews. For sites that run their own surveys, we supply and support the measurement tools. | In-house survey crews | |
| Fragmentation analysis (BLD-FRG-204) | Image-based sizing of the muck pile. Photos of the muck pile are analysed for size distribution and linked to crusher and mill performance, closing the loop from blast to plant. | Size distribution (e.g. P80) | Linking blasts to crusher and mill |
| Vibration & airblast monitoring (BLD-VIB-205) | Seismograph networks for blasting compliance. Permanent or portable seismographs record ground vibration and airblast at sensitive points, with compliance reports for each blast. | Compliance reports per blast | Blasting near communities and infrastructure |
| Design-vs-actual reporting (BLD-RPT-206) | Drill and blast KPIs. Dashboards compare designed and actual holes, charges and results over time, with export to WIRE and mine-planning systems. | Dashboards; CSV and DXF export | Continuous blast improvement |
