Abstract

Quick and accurate advance acquisition of mechanical parameters of rock mass is an important prerequisite for guiding the safe construction of rock mass engineering. Using the self-developed multi-functional digital drilling test system, the indoor digital drilling tests and uniaxial compression tests on complete samples with different strength grades are carried out. Based on the test results and according to the stress characteristics of diamond bit in rock grinding drilling process, the theoretical solution to the rock grinding energy per unit volume is defined and deduced by using the force limit equilibrium and the energy conservation principle. The mathematical equation for digital drilling parameters and grinding energy per unit volume of rock is obtained, and the quantitative relationship between rock digital drilling parameters and uniaxial compressive strength is established, namely RDP-R_c prediction model, and the feasibility and validity of the model are further verified. The research methods and results can provide a new way for the real-time in-situ measurement of strength parameters of rock mass.
