Tailings dam failures
While the mining world is inundated with statistics outlining the horrific consequences of tailings dam failures, LSI Lastem has started a collaboration with RAMJACK TECHNOLOGY SOLUTIONS to make these failures completely avoidable. Because tailings dams are built to last forever, safe construction and monitoring is not only possible, thanks to today’s technology, — it’s critical!
The solution? The G.Re.T.A. system
A new disruptive equipment can now fulfill the technological gap in the field of tailings dams monitoring: G.Re.T.A. (Geoelectrical Resitivimeter for Time-lapse Analysis), the new remote sensing solution designed by LSI Lastem.
The device, based on the Electrical Resistivity Tomography (ERT) method, measures the resistivity of the subsoil over time in an autonomous way, sending recorded data through to a cloud-based software for storage and analysis. G.Re.T.A. can be used also as an early warning system, thanks to the possibility of setting resistivity variation thresholds to be used to trigger alarm messages.
The soil resistivity varies with water content, creation of voids and presence of fluids, such as pollutants that are precisely the most critical factors in tailings dams monitoring.
G.Re.T.A. is an industrialized-off-the-shelf technology for tailings dams monitoring, a new powerful tool to put under control, in real time, those processes occurring inside the dam body that may influence its structural integrity while helping in preventing the risk of failure.
