Abstract:
From three aspects of theoretical research, experimental research and numerical simulation, the research progress of fire wind pressure, fire zone resistance, counter-current layer, critical wind speed and the variation law of smoke flow parameters during fire in mine inclined roadway are comprehensively discussed. The limitations of the existing research are pointed out and its development trend is put forward. The analysis shows that: more attention should be paid to the study of various physical quantities and their influence relations during fire in mine inclined roadway; it is necessary to further establish a large-scale, omni-directional and three-dimensional experimental model of fire in mine inclined roadway, and the factors such as roadway slope, combustible type, fire source position and intensity, wind speed and so on should be taken into account in the experimental process; in physical modeling and numerical simulation, the field conditions should be closely combined, and the interaction between tunnels should be considered. In-depth study of the migration law of smoke flow during fire in mine inclined roadway can lay the foundation and provide technical support for the improvement of the whole mine roadway fire theory and fire rescue.
