The mechanical parameters of a rock mass are the basis for studying the deformation and failure mechanisms and control methods of the surrounding rock in underground engineering. At present, these parameters are mainly obtained through laboratory tests of cores obtained from surrounding rock in the field. It is difficult to core the broken surrounding rock, and a rock core is detached from an environment with on-site stress. The rock mass drilling test can provide a new method to solve the above problems. This paper has developed a rotary cutting test system for rock mass (RCT system) for research on the relationships between drilling parameters and rock mechanics parameters. The basic characteristics and structure of the RCT system were introduced, digital drilling tests of different rock mass specimens were conducted for various control parameters and different bit types. The relationships between drilling parameters, and the response law of drilling parameters to rock mechanics parameters and drill bit structural parameters during rock drilling were systematically analyzed. The research lays a foundation of equipment and theory for implementing testing of rock mass parameters while drilling.
