In order to master the air flow distribution law in the driving face forced with long duct fan accompanied with short duct exhauster during wall-attached jet dust control, the physical simulation tests were carried out in the laboratory under three conditions: only forced ventilation; both forced fan and dust collector fan opened; forced fan, wall-attached duct and dust collector fan all opened. The results showed that, after wall-attached jet dust control, the air flow distribution in the excavating area of roadway is more uniform than that when only the forced fan is opened, and both the forced fan and the dust collector fan are opened, and the airflow speed distribution uniformity coefficient K-0 at the roadway section 3 m from the excavating face increased from 0.68 and 0.70 to 0.83, with an increase of 15% compared with that when only the forced fan was opened, which could facilitate the control of dust dispersion of driving face, so as to improve the dust removal efficiency of dust collector fan; within the area 15 m from the excavating face, the airflow speed near the excavating face was the maximum when only the forced fan was opened, and both the forced fan and the dust collector fan were opened, and it was gradually decreased with the increase of the distance from the excavating face, but in some positions, it increased first, and then decreased gradually after reaching the maximum at the position 3 m from the excavating face; when the forced fan, the wall-attached duct and the dust collector were all opened, the airflow speed from the air outlet of wall-attached duct to the excavating face changed slightly; when only the forced fan was opened, there was an eddy zone within 8 m in the front of excavating face; when the forced fan, the wall-attached duct and the dust collector fan were all opened, there were two eddy zones within 0-8 m and 8-15 m from the excavating face.
