FIELD: mining.
SUBSTANCE: invention refers to protection of environment, particularly to aspects of ecological safety and can be implemented at construction and at development of minerals near active volcano. The method of reduction of dynamic effect of a volcano to environment during eruption includes complex of research in corpore. There is determined a probable hypocenter of an earthquake and probable term of volcano eruption, the depth of bedding and intensiveness of the block system of support zone, the depth of magma collection zone and zones of its probable melting. On the base of received data a loose zone is formed on the slope of the volcano under a crater plug; also depending on a relief of area, on the depth of magma collection zone and on depth of support zone boreholes are drilled from the surface or from a gallery led for this purpose to the center of the volcano. Boreholes are used for preliminary slackening of mountain massif at the first stage by hydraulic break, and at the second stage of mountain massif slackening by leaching. Upon creating a loose zone magma withdrawal channel is formed by the method of directed explosion.
EFFECT: decreasing undesirable consequences of catastrophic volcano activity due to transforming volcano eruption character from violent volcanic into tranquil outflow of liquid lava.
