METHOD FOR LIQUIDATION OF INITIAL STAGE OF UNDERGROUND FIRE

摘要

Method for liquidation of initial stage of underground fires in operating or terminated working in case when one constructs hermetic partition with simultaneous supply of inert gas to coal working is in fact that one places in addition in coal working equipment for control of indicator gases, volumetric content of oxygen, nitrogen, methane and condition of specific physical parameters of atmosphere of working, like pressure, temperature, smoke content of air medium of working, rate of air flow in working, equipment for transformation and transfer of data from different indicators as part of automated system for reveal and liquidation of initial stage of underground fire. The working is closed with at least two or larger number of partitions with gaps between those, with formation of gas chambers. The partitions are equipped with excess pressure valves. As inert gas, one uses nitrogen. Supply of nitrogen and its termination is performed by command by intellectual block on basis of analysis of indications from all the indicators placed in the working.
