Abstract
Nowadays in prospecting and exploration drilling the methods of sinking loose rocks based on their compaction are becoming more and more widespread. Such methods include squeezing and vibratory drilling. These methods are applied at penetration of rocks of I-III categories on drillability for classification of rotary drilling and have high mechanical speed.
