【 摘 要 】

The most economical decision to remove snow in big cities is using thermal snow melting facilities. Snow mass removal, taking place within them, is a complex stochastic process. Nevertheless, it's necessary to have detailed description of melting metamorphism, allowing to get certain regularities, which could be basis of engineering calculations of geometrical and kinematic parameters of the facilities. Methods and results of experimental studies, conducted with the purpose to find out dynamics of melting process depending on basic factors, effecting operational process: density of snow mass, grades of its pollution, temperature of heat carrier and character of its interaction with processed environment, have been narrated in the article. The received experiment results are foundation for physical modelling of operational process and getting criterion equations as dimensionless quantities for distribution of found relations for all the similar systems.
