Abstract
In order to decrease coal dust pollution of industry square, two types of dust-controlling equipment of main fan diffuser of coal mine are designed by virtue of inertia separation and gravity sedimentation. On the basis of field conditions, the physical models of two equipments are constructed. In application of Computational Fluid Dynamics (CFD), dynamic and kinetic fields of two-phase flow in two equipments are researched. The results show that the application of dust control equipment of main fan diffuser is available approach of decreasing coal dust pollution in industry square of coal mine.
