Abstract


There are a lot coal dust sources points including transferring point , coal-falling pipes. Because of induced wind, there are many coal dust sources such as the above. Transportation of coal from the above to the below, with the bulk of coal will cause induced wind. High-pressure air flow will be caused in the limited space. And coal dust in the high-pressure air flow spreads into the workshop results in the pollution. Currently, Coal dust control equipments are focused on research. But, dust pollution caused by airflow induction will be not focused. Therefore, not only will be the numerical simulation study of the regularity of the dust transport based upon the induced wind carried on, but also a strong scientific basis about coal dust control plan will be made.Based on the above, the gas and solid two phase flow mathematical model based on induced wind will be established in Fugu Coal Preparation Plant, Shanxi province. And the numerical analysis will be carried on. The research involves the theoretical and numerical simulation which could apply to various industrial and mining enterpriseswhere dust prevention exists as an reference.
