artificial snow systems are also used for maintaining the snow cover of the ski stages for a longer time. It is usual for the system of artificial snow to be used for providing appropriate conditions for early beginning of the season (even in November), as well as prolonging the season (end of April). Artificial snow also is used for adding of snow that is used from the daily use of the ski stages by the skiers. Instalation of equipment for production of artificial snow will provide a sure beginning and a late end to the season with the needed snow cover. In order for the ski season in one ski area to be opened and to remain openened with a significant number of skiers it is accepted that on the ski stages there needs to be a minimum of about 50 centimetres of layered snow on a surface that has been previously prepared and processed with the purpose of providing quality surface for skiing and snowboarding. Smaller than the recommended depth depending on the field conditions can result in the appearance of vegetation or rocks through the snow surface which can damage both the vegetation and the skiing or snowboarding equipement, as well as the speeding up of the melting of the snow cover. The artificial snow system should be dimensioned with an appropriate capacity for making 50 cm snow depth, which will provide opening of the ski season. Besides this the capacity of the artificial snow system should allows making of about 1 meter of snow cover in order for the basis to be incresed and the adequate depth to be maintained throughout the season because the height of the snow are lessened because of tamponing, sublimation and vaporation. This additional snow will provide a long term, quality surface that will take on a big amount of skiing passages. The ski center with the artificial snow usually opens the center in phases, with making the snow in various zones on the mountain in the duration of consecutive periods of time.
