Abstract: To address the issue of low dust removal efficiency due to the mismatch of ventilation and dust removal equipment parameters in the fast excavation working face of Menkeqing Coal Mine, the comprehensive excavation simulation test analysis laboratory was utilized and modified to simulate the working conditions of the fast excavation working face. Through similarity simulation experiments, the parameters of long-pressure and short-extraction, including the distance of the dust extraction port, air supply volume, dust extraction volume, diameter-to-axis ratio, and dust control duct distance, were adjusted to derive the distribution pattern of dust concentration within the fast excavation tunnel. Based on this pattern and in accordance with on-site requirements, the equipment parameters of the fast excavation working face in Menkeqing Coal Mine were adjusted to the optimal parameters. After measuring the dust concentration, the results showed that the dust concentrations at the positions of the excavation anchor machine driver and at heights of the breathing zone 5, 10, 15, 20, and 25 meters behind the driver position were reduced from the original 1231.5 mg/m³, 984.9 mg/m³, 663.7 mg/m³, 306.2 mg/m³, 236.7 mg/m³, 159.3 mg/m³ to 136.3 mg/m³, 76.4 mg/m³, 57.1 mg/m³, 33.5 mg/m³, 19.4 mg/m³, 7.1 mg/m³ after adjusting the process parameters, with dust reduction efficiencies reaching 88.9%, 92.2%, 91.4%, 89.1%, 91.8% and 95.5%, respectively.
