Research on the influence of coal mine dust concentration on UWB ranging precision
Gong-kuang zidonghua, 2021 The environment of the fully mechanized working face in coal mines is harsh and the dust concentration is high. When ultra wide band (UWB) is used for positioning, it is easy to be interfered by dust.

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.
