New diesel exhaust analyser to boost mine safety

Queensland now has a state-of-the art analyser to help improve safety in mines where diesel engines are used, Mines Minister Geoff Wilson said today.

Developed in the United States, the thermal-optical carbon aerosol analyser will be used to monitor carbon matter in ultrafine particles in diesel exhaust, to ensure exposure levels are within accepted guidelines.

Ultrafine particles are one hundred times smaller than the diameter of a human hair.

Mr Wilson said the Department of Mines and Energy’s Safety in Mines Testing and Research Station (Simtars) would use the analyser to reinforce their existing exposure assessment service.

“Simtars scientists already conduct noise and dust exposure assessments for the mining industry,” Mr Wilson said.

“Diesel particulate matter exposure assessment is another tool to improve health and safety in the industry.

“While we’re reaping the benefits of the resources boom, we should never lose sight of the importance of safeguarding the safety and health of mine workers.”

To determine worker exposure to diesel particulate matter, a sample of air is collected onto a filter at the work site during mining activities. This is then sent to Simtars’ Redbank laboratory in Brisbane for analysis.

The results of the analysis are compared with current mining industry guidelines to ensure exposure levels are acceptable, and Simtars advises mine management as needed.

Mr Wilson said the analyser was one of only three or four in Australia.

“A Queensland-owned analyser means Simtars can provide a more efficient service, as samples will no longer be sent interstate for analysis.”

Mr Wilson said diesel-powered equipment had allowed the mining industry to achieve tremendous improvements in productivity over the past 30 to 50 years.

“The diesel engine is an economical source of power, and diesel-powered equipment is rugged, mobile and versatile. Diesel fuel does not ignite as readily as petrol, and its higher flash point makes it invaluable for underground coal mines.”

Diesel engines used on roads, rail or underground emit a smoky black exhaust due to the incomplete combustion of diesel fuel.

Mr Wilson said some diesel exhaust compounds, especially diesel particulate matter, could potentially affect the health of workers if inhaled, so workplaces needed to monitor and control exhaust fumes.
