METHOD FOR FIRE FIGHTING IN MINES

摘要

FIELD: mining.SUBSTANCE: method includes supply of inert gas in mined space in liquid condition. At the same time the inert gas is supplied in a tightly closed reservoir with a broken shell. The reservoir shell is damaged at the specified temperature and is controlled by variation of dimensions and mechanical strength of the shell. Tightly sealed reservoirs are fed to the mined space along wells drilled from the surface or from mines, or are placed in the mined space at the bottomhole side, if lava is moving.EFFECT: improved efficiency of fire fighting in mines, safety of mining works.2 cl
