Journal ArticleDOI
Effect of air flowrate on pollutant dispersion pattern of coal dust particles at fully mechanized mining face based on numerical simulation
TL;DR: In this article, the effect of air flowrate on pollutant dispersion pattern of coal dust particles at the fully mechanized mining face is investigated. And the authors aim to reduce the dust concentration through adjusting the air flow rate parameter.
Journal ArticleDOI
Numerical simulation study on dust pollution characteristics and optimal dust control air flow rates during coal mine production
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 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.
Journal ArticleDOI
The diffusion of dust in a fully-mechanized mining face with a mining height of 7 m and the application of wet dust-collecting nets
TL;DR: In this paper, a novel dust removal system, comprising wet roller-shutter, dust-collecting nets in the coal mining area and full cross-section, wet dust collecting net in the return airway, was designed.
Journal ArticleDOI
The effects of the spraying pressure and nozzle orifice diameter on the atomizing rules and dust suppression performances of an external spraying system in a fully-mechanized excavation face
TL;DR: In this paper, the ANSYS-FLUENT software was used for investigating the atomizing properties and the related variation rules of the nozzles with different orifice diameters (1.6, 2.0, 3.4), under different spraying pressures from 1 MPa to 5.5
