FIELD: mining.
SUBSTANCE: as per one version of implementation, the method involves well shaft drilling by a drilling bit, determination of an axial load on the bit during drilling of the well shaft, determination of pressure drop in the working surface area of the drilling bit during drilling of the well shaft and determination of the corrected axial load on the bit as per a certain axial load on the bit and a certain pressure drop.
EFFECT: creation of improved drilling bit and method allowing to correct changes in measurement results of an axial load and torque, which occur due to pressure drop in the drilling bit.
