Direct costs of dust-induced illnesses from coal mining exceed $1 billion per year, but fundamental mechanical knowledge of particle generation is meager. This research uses fracture mechanics theory, experiment, and application to explain how fine coal fragments (respirable dust) are generated during coal cutting.
