Numerical Simulation Study of Coal Gangue Piles Influence on the Wind Pressure Distributions of Coal Reservoir Roofing

Abstract:

The influence of the wind coefficient distribution on coal reservoirs for coal gangue is very important to its wind-resistance design. Take a real coal reservoir in Ordos for example, the wind pressure is numerically simulated with the help of Fluent Software. Because of the coal gangue piples, the average wind coefficient absolute obviously reduced under most of the wind directions, but the local area on the surface and leeward side the average wind coefficient absolute will increase significantly under the certain wind directions. Anyhow, the coal gangue is important to the wind pressure distributions of the coal reservoir and can't ignore its effect in the actual engineering design and should be given more attention.
