Jan 14, 2022 Coal dust used as a product of coal mining process has seriously threatened production safety of the coal industry, especially in terms of pneumoconiosis (Liu et al. 2020; Yin et al. 2019).With the increase of coal mining strength, the crush degree of coal body was significantly enhanced, leading to the rapid increase of coal dust ( 40 μm) production (Zhou
dust generated at the crusher/stageloader. In response, water sprays should be placed on both sides of the crusher and at the stageloader-to-section belt transfer (Jayaraman et al., 1992). The objective of these sprays is to wet the coal product and prevent respirable dust from becoming airborne. Conse
Airborne dust generation is one of the byproducts of coal mining, processing, and handling. The amount of airborne total dust (ATD, respirable size and larger) and airborne respirable dust (ARD) generated is of primary interest for designing the level of engineering controls needed for adequate dust abatement. Laboratory crushing experiments were conducted in a wind tunnel
