METHOD AND SYSTEM FOR EVALUATING ROCK MASS HARDNESS Russian patent published in 2021 - IPC E21C39/00 E21B44/00 E21B49/00 G05B13/04 

FIELD: mining.

SUBSTANCE: group of inventions relates to the field of drilling blast holes. The system for assessing the hardness of the rock mass during the operation of the first industrial machine contains an electronic processor designed to receive a model of the rock mass, including parameters related to the rock mass located in a given area, receiving live drilling information from the first industrial machine, updating the model of the rock mass based on operational information of drilling, estimates of the drilling index for the well based on the updated rock mass model, and the drilling index includes the properties of the rock mass material, setting the blasting parameter for the well based on the estimated drilling index, receiving operational data on the load from the second industrial machine, designed to collect the blasted rock mass material, wherein the live load data includes at least one selected from the group consisting of payload, digging force, digging energy, movement through the digging surface, and updating the rock mass model based on live load data from the second industrial machine.

EFFECT: improvement of the design solution of the explosion is provided to match the energy of the explosive applied in different three-dimensional locations of the rock mass, the energy of explosive required to obtain homogeneous crushing.
