Abstract:

The test study of triaxial stress for two typic rocks, J_c and T_c, under confined pressures is presented in this paper. It is of great significance to the design of bits and the application of bit types. Some available data for the bit design and the application of bit types are obtained through the test.

Key words: Rock, Stress analysis, Laboratory test
