Abstract: In order to grasp the migration regularities of dust in comprehensive tunneling face of rock roadway with far-pressing-near –absorption ventilation system. On the background of auxiliary transportation lane in the north limb of Zhangcun mine, by using the method of combining numerical simulations and field measurement, the discrete phase model for computational fluid mechanics is used for numerical simulation research of the wind and dust concentration field distribution regularities. The results of research show far-pressing-near –absorption ventilation system can effectively restrain the high concentration of dust diffusing to the rear of roadheader, and the accumulation of dust can be discharged quickly by dust collector, improving the working environment and protecting the workers' physical and mental health.
