Characterization of nanoparticles generated from drilling activities within a sub-surface mine using a novel sampler
This study employed nanoparticle sampling techniques to characterize the aerosol generated from a routine mining activity. A preliminary survey of the particle emission from the feed-leg drilling activity was conducted in the excavations of an experimental mine. The level of particulate exposure was sampled using a novel sampler for respirable and nanometer sized particles; and monitored by direct reading real time instruments. A NanoScan scanning mobility particle sizer (measurement range 10-420 nm) and an optical particle sizer (measurement range 0.3-10 µm) were used. Particulate morphological ...
