Methods of fire localization while maintaining the ventilation mode of coal mines under various development schemes

Abstract

Localization of fire sources is one of the main measures preceding the active extinguishing of fires occurring in underground workings through which fresh air is supplied to workplaces or along which the return air stream moves. Such measures have been developed mainly for cases of opening at a single horizon. They are often automatically transferred to mines with two, three or more horizons, which leads to catastrophic consequences ...
