Sound | Queensland Coal Mine – Sound Attenuation Solution

"You can barely hear the machine from the lookout. There have been comments from the New Acland personnel on how quiet that machine operates.”

Nic Hope – Resource Industries Account Manager

Summary

Operating within strict environmental noise limits is a growing challenge for modern mining operations. This case study explores how a Queensland open-cut coal mine introduced a new Caterpillar 993 wheel loader while maintaining compliance with boundary limits below 42 dB(A), where cumulative site noise is continuously monitored and even small increases can impact operational flexibility.

In collaboration with the equipment supplier, Minetek engineered a tailored sound attenuation solution designed to reduce noise at source without compromising airflow, thermal performance, or OEM specifications.
