The Boddington Mine in Western Australia is Australia’s largest gold mine. It has a Residue Disposal Area (RDA) where it stores the mine tailings residue from gold and copper processing.
The mine owner, Newmont, previously deployed site personnel to manually monitor an extensive piezometer network around the RDA. This was a challenge because the facility covers an area of 12 square kilometers.
As part of Newmont’s RDA dam monitoring work, Worldsensing’s partner Geomotion Australia installed 34 Loadsensing vibrating wire 5-channel data loggers, servicing 125 piezometers in 45 locations, and a central gateway to send data to Newmont’s management software.
Loadsensing uses LoRa, a long-range, low-power wireless technology used by IoT networks worldwide, and a star network topology that can cover a range of up to nine miles or 15 kilometers without any repeaters. The wireless data loggers are also IP-67 certified and have been tested in temperatures ranging from -40C to +80C, so they are able to withstand the harshest environments.
By upgrading from manual to wireless monitoring, the Boddington Mine benefits from the real-time monitoring of the tailings dam. This minimizes safety risks for site personnel and reduces the cost of monitoring such a large area.
