Application of Inert Gas Injection to Mine Fire Rescued
After the fire, closing fire district and filling inert gas is a common and comprehensive disaster relief method. For providing theory basis to analyse the effect inert gas injection (velocity) act on gas in fire zone,determine the amount of inert gas, improve the efficiency and security during applying inert gas injection. The relevant analysis of the paper is example with Fuhua coal mine extraordinarily serious accident and rescue process, analyzes the gas concentration changes within the fire sealing before and after inert gas injection during the actual process of disaster relief. The analysis results show that, the different speed with inert gas injection cause different speed with combustible gas concentration changes, and inert gas injection can reduce air leakage in fire district; at last, obtain theoretical inert gas volume through theoretical analysis, and compare with practical data. The results provide the technology support for improving application efficiency and Safety during the inert gas applied to coal mine fire rescue
