METHOD OF DECREASING DYNAMIC IMPACTS OF VOLCANO ON ENVIRONMENT AT ITS ERUPTION

摘要

FIELD: mining.;SUBSTANCE: method involves complex of full-scale investigations, on the basis of which there created is loosened area in volcano flank under crater plug, and channel for discharging magma by means of directed blast. In addition, around the crater there built is tent from high-strength and fire-resistant polymers with the aerodynamics typical for aeronautical balloons with burner or parachute systems, on the dome of which there fixed are pressure sensors, temperature sensors and gas analysers, which under influence of gas and steam leaving the volcanic neck moves upwards and is remote controlled by means of ropes with tension device, which allows restricting the spread of stones and ash beyond the volcanic crater limits.;EFFECT: decreasing dynamic impacts of volcano on environment during its eruption.;2 dwg
