Zusammenfassung:	An appliance for drying descending blast holes includes a pipe for feeding compressed air and an inflatable element made of elastic material fixed with one end at the pipe. The inflatable element is arranged as a bag, for instance, is made of wasted of explosion sack tare. Length of the bag in perimeter is larger than the length of the perimeter of cross-section of the hole. In the angles of the bottom part of the bag there are provided openings for exhaust of compressed air. Area of the cross-section of each opening is smaller than the area of the internal cross-section of the pipe. The total area of the cross-section of the openings in the bag is equal to the area of the internal cross-section of the pipe.
