On the calculation of impact energy transfer
Authors:
Abstract
In the mechanisms of percussive-rotary drilling (pneumatic and hydro-impactors, etc.) energy transfer for rock destruction is carried out from the piston-impactor or directly to the rock-destroying tip - bit, or through an intermediate link - drill rod, drill pipe - drill bit.
