Abstract

The issues related to computation of contact stresses which occur in the contact patch of drilling tool and tap-hole mix when iron notch opening by means of rotative-percussive drilling method are considered. The recommendations regarding a rational choice of geometrical parameters of boring crowns for iron notch opening machines are presented.
