  • A multifunctional true triaxial rock drilling test system and test method for characterizing rock mass properties

    The present invention uses a multifunctional true triaxial rock drilling tester as a preset test device. The tester has the function of applying true triaxial loading to specimens, capable of simulating the drilling process of a drilling rig under three-dimensional confining pressure in underground engineering. The invention can establish the correlation between drilling parameters and rock mechanical properties of specimens under different confining pressures, providing a process from specimen preparation to data processing...
