Abstract

Based on the review over theoretical and experimental analyses of influence the drilling machine hammer design exerts on the rock fracture process efficiency, the author draws a conclusion that hammers with curvilinear side surfaces are not an optimal choice as they do not provide a noticeable increase in the impact energy utilization while greatly limit the energy transfer to a work face via a drill rod without breaking the rod.
