Research on Plateau Mine Dust Distribution and Optimal Discharging Dust Wind Speed

摘要：

Mine ventilation is a simple and effective removing dust method, but if the wind speed is too large, secondary blowing dust is often caused, resulting in the increase of dust concentration.Natural climate condition of the plateau mine is inferior to the plain mine, ventilation and dust removal effect is not as obvious as the plain mine.In order to effectively control the plateau mine dust, and improve the working face, according to the distribution law of plateau mine dust, through the field test data analysis, the relationship between mine wind speed and dust concentration, and the relationship between mine wind speed and dust dispersion were studied, analyzing the law of secondary blowing dust, in order to find the optimal discharging dust wind speed of mine, which provided a theoretical basis for plateau mine dust prevention.
