FIELD: mining.
SUBSTANCE: invention relates to mining, can be used when selecting places for coal rock dumps location and intended for prevention of rock mass self-ignition. When preparing dumps site creating waterproof layer to design boundaries of dump, insulating layer from inert materials along dump perimeter, selecting boundaries of geodynamic active blocks, determining their effect width b and coal rock dumps sites are located outside these zones.
EFFECT: technical result is prevention of rock mass self-ignition due to excluding possibility of air intake into dump through permeable zones in its base.
