Technological and energy parameters of frozen rock thawing by microwave electromagnetic energy
Abstract
One of the ways of preparing frozen rocks for excavation is thawing. However, the use of traditional heating methods for this purpose can not be recognized as satisfactory, both because of the low rate of thawing due to the low thermal conductivity of frozen rocks, and because of the negative effect of heating sources on the thermal regime of excavation.
