Claim:
1. A method for determining mechanical parameters of a rock sample, comprising: scratching a groove in the rock sample by causing a blade to advance at a constant speed and constant cutting depth along the rock sample in order to destroy a constant volume per unit of length at the surface of the rock sample; measuring horizontal and vertical forces provided to the blade while scratching the groove; performing a micro-indentation test on the rock sample within the groove created by scratching the rock sample; determining mechanical properties of the rock sample while performing the micro-indentation test, and determining geomechanical parameters of the rock sample, comprising determining at least one parameter chosen from among uniaxial compressive strength, angle of friction, internal cohesion, Brinell hardness, and Young's modulus of the rock sample using measurements taken while scratching the groove and while performing the micro-indentation test.
