Abstract: The results of calculating the distributionof inert composition obtained at joint water spray and liquid nitrogen in the mined-out space mines atthe fight with the centers of endogenous fires are given. Change of velocity of the inert in the pile of coal and rock is estimated, depending on the distance from the feed point of the composition. duration of the movement of inert composition from the feed point to the focus and the effect of air velocity in the goaf to the area of its distribution is defined.

Key words: mine mined-out space coal accumulation inert compounds fire underground fire liquid nitrogen
