Study on the Explosion Mechanism of Low-Concentration Gas and Coal Dust
FireIn coal mines, the mixture of coal dust and gas is more ignitable than gas alone, posing a high explosion risk to workers. Using the explosion tube, this study examines the explosion propagation characteristics and flame temperature of low-concentration ...

Detection of coal dust in a mine using optical tomography
International Journal of Mining Science and Technology, 2012 A dust concentration imaging system based on optical tomography is proposed to monitor concentration variations of coal dust in a mine. Concentration profiles, rather than just a point value, of coal dust concentrations are the goal of this method.
