Increased in recent years, the flow of information on the impact of thermal phenomena on the movement of air in the mine during a fire is mainly theoretical in nature. Experimental studies are rare. In the study of phenomena related to the manifestation of thermal depression, the relationship between thermal depression and the amount of air flowing, the temperature in the fire hearth and the location of the fire ... has not received adequate coverage.
In contrast to the previously used in statistical development of the general mine indicator of the number of fires per 1 million tons of production, in this study used the formation fire frequency coefficient, which characterizes the number of fires per 1 million tons of production from a given reservoir. The point is that the all-mine indicator of the number of fires per 1 million tons of production correctly reflects the actual state, provided that the number of fires from the seams developed by the mine is distributed evenly over all seams. In practice, however, such a situation does not happen ...
Локализация очагов пожаров — одно из основных мероприятий, предшествующих активному тушению пожаров, возникающих в подземных выработках, по которым подводится свежий воздух к рабочим местам или движется исходящая струя. Такие мероприятия разработаны главным образом для случаев вскрытия одним горизонтом. Часто они автоматически переносятся на шахты с двумя-тремя и более горизонтами, что приводит к катастрофическим последствиям ...
