Remote tracking of tailings integrity

Remote tracking of tailings integrity

Remote monitoring is keeping an eye on the integrity of tailings dams on one of Queensland’s oldest mine sites.

GlassTerra, which has a Brisbane base, has installed its Internet of Things (IoT) and Light Detection and Ranging (LiDAR) sensors at Mount Morgan, which is managed by the Queensland Government’s Department of Natural Resources, Mines and Energy.

It’s been done to demonstrate the safety benefits of real-time tailings embankments monitoring.

Mount Morgan was shut down in 1990 and is now managed under the abandoned mine lands program which includes on-going monitoring conducted more than 130kms downstream in the Dee River.

The Dee River was contaminated by acidic water from the tailings dam during an extreme flood event in 2013.

The initiative showcases integrated technology using GlassTerra’s geospatial platform together with global satellite connectivity to achieve highly reliable real-time monitoring of tailings embankments said GlassTerra Chief Customer Officer, Sophia Li.

The combined solution would demonstrate the ability to conduct real-time monitoring of unplanned movements of earth and other parameters, on embankments such as tailings facilities, said Ms Li.

“Real-time monitoring of embankments enables prompt reporting, investigation and mitigation of any changes, which can enhance safety, improve the protection of our environment and advance the social performance of the mining industry,” Ms Li said.

It could potentially be applied to the 3,500 tailings storage facilities in the global mining sector, she said.

The technology would also be applied to real-time tailings embankments monitoring in Africa, Ms Li said.
