Improve ways of drilling in blast holes by on ways optimization three dynamic parameters of the drill bits
The paper discusses the issues of improving the drilling blast holes efficiency in three dynamic parameters: fitting-out, sealing of mainstay and flushing knots of rock-destroying tools by developing new technical solutions for creation of the new drill bit cutting-abrasive types in order to ensure efficient operation of the bit pairs in rotation mode with a given eccentricity, that made with two parallel axes of rotation and work surface in the form of matrices, completely overlapping surface downhole mode couples rotation allows perspective pose and solving optimize process problems the destruction at rock drilling.
