Mitigation and Management of Blast Generated Fume in Eastern Australia

The period from 2009 to 2012 has witnessed a large rise in the number of blast-generated fume events in Eastern Australia, where highly visible oxides of nitrogen (NOx) are produced from coal mine blasting. Fume production mechanisms have been poorly understood by mine operators, and practical measures to reduce fume were initially elusive. Over time, data on fume events has been collected and analysis has pointed to a range of contributing factors associated with fume production.
