Abstract.

Underground fires and methane explosions occurring in coal mines are common to almost all mines in Ukraine. The problem of increasing the effectiveness of the fight against underground fires and explosions is of particular relevance due to the complex mining and geological conditions and mining and technical conditions for mining in these mines. With these types of accidents, there is a possibility that some of the workers may end up in smoke filled areas of the mine with an elevated temperature of the atmosphere, many of whom can be saved only by taking them out with the help of mine rescuers. Moreover, it should be borne in mind that, for various reasons, the period of operation of personal protective equipment may not be sufficient to remove people from the emergency site.

To ensure the safety of miners in the implementation of emergency conditions (gas-dynamic phenomena, explosions, fires, etc.), as well as rescuers involved in the elimination of the consequences of these accidents, a number of regulatory documents governing the protection and maintenance of mining operations were developed and further adjusted and the self-salvation of miners.

It should be noted that one of the most serious elements of this protection are rescue chambers to ensure the collective safety of workers and mine rescuers during an underground fire, when the time to overcome the route of workers for a fresh stream of air exceeds the technical capabilities of personal protective equipment. The rationale for such decisions laid down in the regulations and patents.

The main task of the rescue chamber is to provide a breathing atmosphere at the place where underground workers switch to the backup self-rescuer when leaving the workplaces in the atmosphere unacceptable for breathing on routes where, if an accident occurs, the actual exit time exceeds the protective action of the self-rescuer or the discharge of underground workers if it is impossible movement along the emergency exit route. And also to ensure the maximum length of the route survey of emergency workings and sites HGGSS mine rescuers in an unsuitable atmosphere for breathing.
