FIELD: environment protection. ^ SUBSTANCE: loosening area and a channel of magma discharge are created by a method of direct blasting. A wind channel is erected near a volcano crater from a polymer film with hoops as stiffening ribs. A filtration plant comprising electrified grids and nets from coal plastic is arranged inside the pipe. The wind channel, using polymer ropes laid along its walls, is lifted to the required height with the help of balloons or aerostats. ^ EFFECT: lower effect from discharge of stones and ash in process of volcano eruption to environment, confinement or elimination of pyroclastic flows. ^ 2 dwg |
