The intention - work up of suggestion for perfekting of existing technologies and creation of new technologies of the industrial processes. The methode of research - the analysis research of the zone contact drill bit to rock temperature by parameters of the drilling; experimental research to pass of the waving energy over the metallic pilot by influence temperature and impulse power. The recommendation work up by thermomechanical hole drilling perfectioning. The drill bit resource increases to 2...3 times, the mechanical drilling velocity increases to 1,5...2,5 times. The using branch - the well drilling in hard rock. Product Description popup.authors popup.nrat_date 2020-04-02 Close
