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
