The Resources Regulator will lead a causal investigation into an incident at Peak Gold Mine last month where there was an unexpected initiation of electronic explosive detonators. 

The misfire incident occurred at Peak Gold Mine’s New Cobar and Chesney site on 18 May 2022. No-one was in the vicinity of the misfire and no-one was injured. 

On the day of the incident, two locations were loaded for firing with electronic detonators. The electronic detonators were placed at a development face and a stope at the mine site. The system was designed to fire simultaneously, however there was a communication issue and the system would not initiate.

The shotfirer working at the development face replaced the electronic detonators at the development face with more conventional electric detonators that could be fired from the 240-volt mains firing line. The intention was to fire the development face only.

The stope shotfirer was expected to do further investigations before the stope was fired. The development shotfirer did not disconnect the original stope electronic detonators before firing the development face. 

The detonation at the development face occurred as the workers expected. However, the stope partially initiated and there was evidence of cratering and rock/emulsion ejection. This was completely unexpected and should not have occurred due to the different firing signals required by the two different types of detonators to commence initiation.

More information is available on our website and an Investigation Information Release (IIR) will be published on our website within a fortnight.

Quarterly safety report released for January to March 2022 

The quarterly safety report for January to March 2022 has been released to better inform industry when reviewing safety management systems and undertaking risk assessments at their sites. The report details incidents and trends relating to hazard management, in addition to sector specific information.

In the January to March 2022 period, total incident notifications received by principal hazard were down (from 178 to 161). This figure represents a 13% reduction from the quarterly average (185) recorded for the previous 4 quarters.

Air monitor detects silica dust in real-time

The NSW Government’s Centre for Work Health and Safety has announced the creation of an air monitor that can detect and monitor silica dust in real-time.   

The new detector is an initiative of the NSW Dust Strategy 2020-22 to tackle dust diseases, that include silicosis and asbestosis.  
The Government invested $1.3 million over three years to support the research and development needed to bring the Air XS to market. 
The device provides an alert when silica levels are high allowing workers, safety representatives and managers to respond instantly to changing levels of dangerous particulates. Previously the only way to know if workers were exposed to dangerous levels of silica was to send air samples to a lab and wait for days or sometimes even weeks for results.
