Remote control technology and numerical analysis of airflow in coal mine fire disaster relief process
Abstract：Aiming to research the process of air flow remote control technology and best air distribution during disaster relief, by using mine ventilation, fluid dynamics and combustion theory, this paper analyzed the influence on air quanti- ty regulation of fire spread speed, smoke back flow, and the phenomenon of leapfrog during fire disaster relief process. Combined with actual situation, analyzed the change of ventilation network before and after fire disaster relief, calculat- ed fire area wind resistance and regulation wind resistance of air doors under four kinds of different openings. Based on ventilation network calculation technology, the best air distribution and fan operating conditions were obtained during disaster relief process. Remote air quantity regulation and control method were put forward, air quantity of smoke and non-smoke area monitored and real-time display, and adjustable opening of air doors structure and remote control pro- gram were designed.
