The methodology of the evaluation of the dissemination of dust in the complicated terrain after the dust-proof walls
 Nosek, Štěpán ; Jaňour, Zbyněk
The report describes the methodology for the assessment of the spread of coal dust from surface mine in the complicated terrain after the dust-proof walls. First, the methodology is described that uses physical modeling, specifically the so-called Townsend´s method of independence on Reynolds ' number is applied. The methodology is applied to the case of the spread of dust from the surface of the coal mine Libouš in the case where a substantial source of pollution in the vicinity is located the dust-proof wall and the diffusion of dust particles is studied in the immediate vicinity of the source. After the configuration of set up of the wind tunnel that simulates flow in MVA in the scale, was made the measurement of turbulent characteristics of flow and diffusion, and was designed by its optimal configuration. The results were compared with the results of the SW.
