摘要
Abstract
This paper is intended to investigate the influence of fire source location and ventilation rate on the smoke migration in fire.The study explores the airflow direction during catastrophe period and proposes the airflow control method by using the scale reduction test and numerical simulation.The results show that the law of smoke migration varies with the location of fire source.When the fire occurs in front of the transport roadway of the working face,the smoke is diverted at the junction with the critical wind speed of smoke back-layering by 1.5-2 m/s.When the fire occurs behind the transport roadway of the working face,the smoke is transported along the belt transport roadway to the return air roadway,and the back-layering smoke is diverted at the junction,while part of it is transported to the transport roadway of the working face,and part of it continues to back-layering with the critical wind speed of smoke back-lay-ering by2.5-3 m/s.This study can provide reference for the formulation of the disaster emergency plan during the period of underground fire disaster in coal mine.关键词
