TL;DR: In this article, a highly simulated physical model of the goaf and multiple dust sources were established in order to obtain the optimal dust-removal air flow rate in the roadway, by combining the numerical simulation method, the influence of the flow rate on dust diffusion rules of the dust sources was analyzed.

TL;DR: In this paper, a new dust suppression gel was prepared by graft copolymerization of itaconic acid-acrylic acid polymer and bentonite, which had excellent wind erosion resistance and could effectively reduce the occurrence of coal dust during coal transportation.

TL;DR: The dynamics simulation results showed that APG-12 molecules can be easily adsorbed on the surface of coal molecules and then adsorb water molecules around them under the action of hydrogen bonds, consistent with the results of an analysis of the system's radial distribution function and the relative concentration distribution of each component in the Z-axis direction.

TL;DR: By combining a molecular dynamics (MD) simulation approach with experimental measurements, the authors elucidated the molecular interactions between the fatty alcohol polyoxyethylene ether-9 (AEO9; ie, a surfactant) and lignite.

TL;DR: In this article, an environmental friendly spray dust suppressant with improved wettability and coagulation properties was developed by a chemical modification method, which was synthesized by nucleophilic substitution reaction between natural polymer guar gum and propylene oxide.
