FIELD: mining.
SUBSTANCE: invention relates to the mining industry, it can be used in the selection of places for the arrangement of coal-dust dumps and is intended to prevent spontaneous combustion of the stockpiled rock mass. When preparing dumps site create waterproof layer to design boundaries of dump, an insulating layer of inert materials along the perimeter of the heap and landscaping of the heap slopes, assessing the stressed state of the massif and the location for the location of the dump is selected outside the tectonically unloaded zones of the mountain massif.
EFFECT: prevention of spontaneous combustion of stockpiled rock mass by excluding the possibility of air entering the dump through the permeable zones at its base.
