To evaluate core disking rock stress and tensile strength via the compact conical-ended borehole overcoring (CCBO) technique, the mechanism of core disking by means of the CCBO technique is discussed. It is simulated that overcoring of the CCBO under three-dimensional initial stress state coincides with borehole axis and is one of principal directions. The characteristics of induced stress and initiated...
