FIELD: ecology.
SUBSTANCE: method includes a complex of survey in full scope, which is used as the basis to develop a loose area at a volcano slope under a crater plug and a magma drainage channel is developed by the method of directed blast. A cover-like structure is created around the crater, which is made of a metal electrified grill with stiffening ribs and is raised with the help of balloons or dirigibles at the required height upwards and is controlled remotely by means of ropes with tightening devices. An apron of high-strength and fireproof polymers is attached to the lower part of the design along its perimetre, which makes it possible to limit throwout of stones, crushed stones and sand, and also to filter a flow of heat from dispersed particles. Around the crater and along the volcano slopes there are pipes laid with nozzles, along which foaming or heat-absorbing liquid is injected, which coagulates ash particles and makes them fall near the crater.
EFFECT: reduced effect of stones and ash throwout in process of volcano eruption at environment.
