Abstract
In spite of the certain success in ice drilling technology, there are enough accident examples of the deep coring in so-called warm ice, which is characterized by the increasing of ice crystals and has temperatures closed to the pressure melting point. The generally accepted recommendations for choosing of rational drilling parameters in such ice don’t exist. The low reliability of the drilling process as often as not resulted to the one of the most severe accident in the hole – sticking of the core drills. The effective accident elimination is possible due to the ice dissolving in the sticking zone by the delivery in this zone of the solvent active to ice, for example, ethylene glycol or its aqueous solution.
