| Izvleček: | Title screen There are many types of ejector pellet impact drill bit providing impact rock drilling. Basic types of drill strings have been regarded, the essential requirements for the most efficient facilities to drill hard and tough rocks are formulated. With regard to these requirements, the ejector pellet impact drill bit design appropriate for operating under given conditions has been proposed.
