Abstract
The problems of monitoring physico-mechanical rock properties during drilling as part of the Smart Mine project to build a rational ore flow system are considered. The theoretical foundations of determining the variability of rock physico-mechanical properties during drilling, mainly elasticity, are presented as a parameter characterizing the elastic response of rock to failure. The basic design of the system for implementing the above mechanism with fixing the variability of the elastic reaction of rocks to failure by elastic strain of the drill string and visualization of the obtained data in real time is given.
