Abstract: The formation problem in fragile medium of holes of various cross-section, including not round is presented. Designs of machines and the devices are shown, allowing solve the problem. Possibility reception of holes of not round cross-section by destruction by impact affectings without turn of the tool round own geometrical axis is proved.

Key words: impact destruction drilling blast-hole not round hole
