Background Information

Background Information

Diesel Exhaust

Diesel Particulate Matter (DPM)

The Size of DPM

• 80%-95% DPM mass consisting of particulates

smaller than 1 μm

• It can reach the deepest part of the lung

Health Effects

• 1988 National Institute for Occupational Safety and Health—

Creteria Bulletin No.50

• 1989 International Agency for Research on Cancer—Group 2a

And 2012– Group 1

• DPM is carcinogenic to humans.

Regulation

• 2001 First Law by Mine Safety and Health

Administration(MSHA) 0.16 mg/m3 (TC)

• Germany– 0.3 mg/m3 for non-coal mines and 0.1 for all other

activities

• West Australia—2007 AIOH– 0.1 mg/m3

Sampling Method

• Area Sampling
• Personal Sampling

DPM Monitor

• Real-time monitor
• Battery-12 hours
• Filter-12 hours
• Info can display on LCD screen
• Data can transfer to PC
• Need to change filter

The Ventilation System

Control Method

• Ventilation
• Admin Control
• Engine Maintenance
• Environmental Cab
• DPM Filter
• Fuel
• Electrostatic Filter Masks

Ventilation

• Mine Ventilation Society Australia 2013—0.32m3/s/KW

Need 529m3/s, Current flow is 130 m3/s

• NSW Department of Primary Industries 2008 – 0.19m3/s/KW

Need 314m3/s, Current flow is 130m3/s

DPM Filter-99%

Truck=$39455*2 Bogger=$28630*3 Jumbo/LH=$8245.9*2 Twin=$9121.55 Sum=$190,413 Optional IT=$22091.11 JCB=$9213.55 Sum=$221,717

Conclusion

• DPM is carcinogenic to humans.
• DPM influenced by 1, Ventilation 2,location 3,machine idle
• The filter is the best control method
