Numerical simulation and application research of mine fire emergency rescue system
Abstract：In order to cope with the fire disaster in the main ventilation roadway,researched into plume dispersion in the ventilation system after belt and electrical apparatus fire in the intake airflow roadway.Mine fire emergency rescue system was established,through preinstalling many groups of remote monitoring air doors,in the crossheading between two main intake airflow roadways set up normally open air door,and set up blocking air door between the intake and return airflow roadway.During the disaster through remote monitoring to close the normal open air door and open the blocking air door,so as to prevent smoke from the working area,but import it into return airflow roadway.Established mathematical-physical model using fire dynamic simulation software of FDS to simulate and contrast the change of the smoke flow movement path before and after starting emergency rescue system.Under the conditions of point and line fire,simulated fire spread,smoke movement and temperature distribution,in order to guide ground to monitor and control the smoke underground,and prove the feasibility and practicality of emergency rescue system.
