| Abstract: | The working face of open-pit mine is characterized by numerous mechanical equipment and a large ventilation volume. During continuous shearer operations, the emission of coal dust considerably impairs the clarity of the working environment, thereby compromising safe production. Nevertheless, current dust suppression devices exhibit limited atomization coverage and insufficient consideration of atomization characteristics. Based on the Bernoulli equation and related theories, the relationships among the characteristic parameters of nozzle jet were analyzed. A multi-channel duckbill dust suppression device was subsequently designed, its structural configuration was optimized, and both internal and external flow fields were numerically simulated. The influence laws of key parameters, including nozzle outlet diameter, inlet pressure, outlet velocity, atomization angle, and total flow rate, on the jet characteristics were systematically clarified through the application of a coupled simulation method. The linear relationships among the characteristic parameters of the nozzle were established by the response surface method. Significance testing confirmed that the prediction model exhibited excellent agreement with the observed values, thereby completing the parameter optimization. Subsequently, the orthogonal experimental method was employed to investigate the influence of multi-factor conditions on the dust suppression performance of the jet. The experimental results demonstrate that the dust suppression rates at the driver's position, the coal cutting area, and the dust suppression outlet, when utilizing the optimal parameter dust suppression device, are 89.3%, 90.0%, and 90.2%, respectively. Furthermore, the coal dust concentration at all test sites is below the relevant safety standard of 100 mg/m³. [ABSTRACT FROM AUTHOR] |
