MOUNT Thorley Warkworth open-cut mine will be the first Hunter mine to trial the latest noise monitoring technology.
A new directional noise monitoring system will be installed in the southern area of Bulga village to assist with monitoring and managing noise from the mine.
The environmental noise compass will enhance Coal & Allied's existing noise monitoring system, which currently involves eight monitoring devices surrounding the mine.
The compass uses an array of 26 microphones and advanced acoustic signal processing methods to detect and assess multiple noise sources in real time with greater accuracy.
"We are continually looking to improve the way in which we manage our activities, and we're proud to be the first mine to utilise this new technology," Mount Thorley Warkworth general manager of operations Cam Halfpenny said.
"Investing in this cutting-edge technology is another demonstration of our commitment to continuous improvement and effective noise management."
Coal & Allied NSW environmental services manager Andrew Speechly said the new system would allow Mount Thorley Warkworth to be more effective in its real-time management of noise by measuring the sound energy of mining activities as they happen and responding accordingly.
