Application of Pre-Grooving Assisting Conical Picks Cutting Hard Rock and Effects of Cutting and Kerf Parameters on Rock-Cutting Performance
Pre-grooving is an effective means of facilitating hard-rock cutting with conical picks, reducing pick wear, and improving rock-cutting efficiency. However, research on the effects of matching cutting parameters with kerf parameters on rock-cutting performance remains limited. Using granite with a strength exceeding 13...
