It plays an important role in dust prevention and control to master the dust migration law of cutting dust source in continuous mining face. This paper takes 15218 continuous mining face of Hongliulin Coal Mine in Shaanxi Province as the research object, and uses Solidworks to construct the physical model of continuous mining face. Based on Euler-Lagrange method, CFD software is used to simulate the dust migration law of continuous mining face under different wind speeds. The results show that the simulated dust concentration is basically consistent with the field measurement results. The migration of dust is mainly affected by the impact jet zone and moves to the return air side. It is mainly distributed in the triangular area below the cutting drum of the continuous miner on the return air side and the continuous miner body and the shuttle car body area. Cutting drum of the continuous miner on the return air side and the continuous miner body and the shuttle car body area. The dust concentration in the eddy current zone is less and the concentration is lower. At the cross section of 1.5m height of human respiration, the area of high concentration dust cloud decreases with the increase of wind speed, and the decrease range decreases gradually. The dust concentration fluctuates along the roadway direction, and the increase of wind speed has a good effect on the dust removal in the high concentration dust area. The number of fine dust, fine dust and coarse dust showed an increase-decrease-increase-decrease change with the increase of wind speed, and the distribution was the least at 1.6m/s. The proportion of dust of each particle size was 15%, 42% and 43%, respectively, and the proportion was relatively stable with the change of wind speed. The research results can provide some guidance for dust control in continuous mining face.
