This study demonstrates the roadheader performance prediction ability of previously developed vertical rock cutting rig (VRCR). Conical pick cutting tests were conducted on selected rock samples in both relieved and unrelieved cutting modes to determine the relationships between dependent and independent parameters in rock cutting and to investigate the optimum cutting condition. It was seen that relationships among dependent and independent variables match up with previous studies. Furthermore, two roadheader sites were visited, rock samples were collected and cutting rates of roadheaders were recorded. Rock cutting tests on these samples showed that performance prediction with VRCR is a plausible option.
