What we do
• We measure ground deformation using
RADAR satellites (InSAR technology) with the
highest quality.
• Our monitoring is totally remote. No installation,
no maintenance.
• We detect geotechnical precursors on time to
reduce operational costs and to contribute to
safety in mining areas.
Reliable and millimetric
precisions on rapid reports

On Friday 9th of March 2018, Cadia gold mine, suffered a
Forecasting Indicators collapse in the TSF embankment. DARES has developed
numerous back analysis to validate the acceleration index

• Back analysis of TSF Cadia gold mine, New South Wales, Australia. 9th
of March of 2018.
Forecasting Indicators • DARES analysis detects acceleration 3 weeks prior to the event.
Acceleration areas • DARES can estimate the date of collapse using regresión techniques

Monthly Report Example. PDF Report
Deformation
Measurements
• The report shows monthly
accumulated deformation over the
área.
• Deformations are shown in colours.
No colour implies no deformation
(stability)
• DARES delivers pdf reports,
visualization interactive online
software and the Data in various
formats (DXF, Shapefile, CSV, etc)
• The data results can be uploaded into
the most relevant geotechnical
software (Canary, ArcGIS,
Geoexplorer, Sensemetric, ACAD,
Leapfrog, Vucan and others)

DARES detects and analyses all
the relevant time series,
showing those who may
represent a potential failure.
Time series are geolocated in
UTM or local coordinates (not
shown in this example)

The time series analysis can
prevent most of the failures
