Abstract

A method for preventing snow from melting and for packing a snow cover in an artificial ski facility, by injecting dry air or low-temperature air to permeate through a snow cover of an artificial ski facility. The entirety of the snow cover can be effectively cooled to reliably prevent snow from melting and to pack the snow cover as well. If high-temperature air is injected before the injection of the low-temperature air, the low-temperature air is permeated effectively and formation of frozen snow is prevented by the high-temperature air injected thereafter. In these methods, snow can be prevented from melting and the packing of the snow cover can be achieved more effectively, if the dry air, the low-temperature air, and the high-temperature air are injected from the bottom of the snow cover, through a header having a plurality of air injecting outlets. The header is preferably constructed in a tortuous or snake-shape or in a lattice, on a platform of the ski facility.
