Research procedure for coal dust aerodynamics in long roadways

This article addresses the urgent problem of fire prevention and safety of mining practices connected with production, handling, processing and storage of coal raw material. The studies focus on fire hazardous and explosive airborne dust concentrations and depositions on process equipment and in hard-to-reach places. The article describes selection, validation and test of a research procedure for aerodynamic properties of coal dust in long horizontal and inclined roadways. The practical part of the procedure is based on the actual test data obtained using the aerodynamic test bench designed by the authors. The aerodynamic modeling and design of coal dust patterns in long horizontal and inclined roadways are implemented in ANSYS Fluent. Testing of the procedure showed a good agreement between the experimental results and the author’s mathematical model data. The same output was obtained in the similar investigations. This means that the presented mathematical model is worth of experimental validation and improvement. The procedure described in this paper can be used to model coal dust flow and deposition during mining, handling, re-handling and storage of coal raw material, which can enable prediction of places of fire-hazardous and explosive concentrations of airborne dust. The research findings are applicable in elaboration of measures aimed at reduction or elimination of hazardous dust concentrations toward precaution and prevention of settled coal dust explosions.

Keywords: coal dust, aerodynamic properties, roadways, Rosin–Rummler equation, SST model, airborne dust, explosive dust.
