Based on the computational fluid dynamics and mine ventilation theory, the geometrical model of the fully mechanized excavation face under the conditions of long-short and short-pump ventilation system was established with the comprehensive mining face of the 905 transportation lane in Shanxi Coal Group. The FLUENT software is used to simulate the distribution characteristics and variation of the wind flow field and dust field in the three-dimensional space of the fully mechanized excavation working face at different air supply speeds, and the simulation results are verified by field test. According to the numerical simulation study and the on-site measurement results, the optimal position of the dust migration law of the fully mechanized excavation face under the long-short and short-drain ventilation mode is determined, and the rationalization suggestions for the mine dust control are put forward.
