Geological Exploration in the Cryolite Zone: Reducing Environmental Risks by Ensuring the Temperature Condition

Abstract

The article suggests one of the directions to solve the ecological problem of cryolite zone destruction during geological exploration. For the first time, the authors offer to use vortex tubes for this purpose. The technique is given and the results of experimental work on the use of a vortex tube to provide subzero temperatures of permafrost during drilling operations are considered. A scheme is proposed and mathematical modeling of the process is performed. As a result of the model study, the technological parameters ensuring the preservation of the cryolite zone are obtained.
