At present, study of coal mine dust mainly focuses on the specific area of concentration distribution of particles of different diameters, and the trajectory of the research, especially the numerical simulation research is rarely involved, this paper applies the method of numerical simulation, and the establishment of dust particles starting mathematical model, research dust in coal mine roadway within the two flying of dust flying, aiming at the two problems, putting forward reasonable and effective methods to prevent the harm caused by secondary dust flying. |
