| Popis: | The authors discuss the issue connected with drilling trajectory deviation and present the technique of rotary–percussion drilling with a down-the-hole air hammer. The article describes pilot testing of the air hammer drill PNB76 in Berezovskaya Mine. The ways of improving the air hammer drill are identified, and the basic diagram and R&D test data are given. |
