Experimental Investigation on the Effects of Cutting Direction and Joint Spacing on the Cuttability Behaviour of a Conical Pick in Jointed Rock Mass

In this study, a series of rock cutting tests was conducted using a conical pick to investigate the effect of joints on roadheader performance. Tests were performed on intact rock and jointed rock mass specimens with three different joint spacings. The results indicate that cuttability is enhanced i...
