Coal Dust and Explosions in Mines Report Findings
The Bureau of Mines outlines how coal dust and rock dust mix affects explosion spread. It notes that fine coal dust rises risk and that unburnable dust can dampen or fail to ignite, while volatile matter in coal increases detonating potential. Experiments in Pittsburgh and Europe show dust composition and dust mixing crucial to explosion dynamics.

Dust Explosions in Mines Highlight Moisture and Ventilation
The article discusses how coal dust and moisture affect mine explosions, noting that drier conditions increase risk. It explains how summer heat and humidity change dust suspensions, and how ventilation and water spraying reduce danger. It cites studies from Pittsburgh and UK mines and stresses drying and controlled moisture to prevent incidents.
