【 摘 要 】

At present, most scholars use the mathematical model of FLUENT software to simulate migration and settlement process of dust, and tend to focus only on the graphical simulation results. For intermediate operation principle and process is not very clear, simulation results of commercial software will easily lead to distortion of simulation results. Based on this, the migration and settlement process of flowing dust in return airway of coal face has carried on the further analysis and research in this paper, and the main factors affecting the dust migration and settlement are analyzed comprehensively. At the same time, according to the law of mass conservation, a three-dimensional mathematical model of migration and settlement of flowing dust is established. The purpose is to reveal the migration and settlement law of flowing dust.
