Abstract

Systems and methods for estimating a hardness of a rock mass during operation of an industrial machine. One system includes an electronic processor configured to receive a rock mass model and to receive live drilling data from the industrial machine. The electronic processor is also configured to update the rock mass model based on the live drilling data and to estimate a drilling index for a hole based on the updated rock mass model. After estimating a drilling index for the hole, the electronic processor is also configured to set a blasting parameter for the hole based on the estimated drilling index.

First claim

What is claimed is:

1. A system for estimating a hardness of a rock mass, the system comprising:
an electronic processor configured to
receive a rock mass model including parameters related to the rock mass located in a specified area,
receive live drilling data from a first industrial machine,
update the rock mass model during operation of the first industrial machine based on the live drilling data,
estimate a drilling index for a hole based on the updated rock mass model,
set a blasting parameter for the hole based on the estimated drilling index,
receive live loading data from a second industrial machine configured to collect blasted rock mass material, the live loading data including a digging force; and
update the rock mass model based on the live loading data from the second industrial machine.

2. The system of claim 1 , wherein the rock mass model is based on a material property of the rock mass.

3. The system of claim 2 , wherein the material property of the rock mass includes at least one selected from a group consisting of a composition, a hardness, a location of a fault plane, and an abrasiveness.

4. The system of claim 1 , wherein the live drilling data includes at least one selected from a group consisting of a depth of a drill bit, a rate of penetration, a pull-down force, a rotational speed and torque of the drill bit, a hydraulic pressure, a flow rate, an electrical signal, and a pose of the first industrial machine.

5. The system of claim 1 , wherein the drilling index includes an identification of a material property of the rock mass at a location within the rock mass.

6. The system of claim 1 , wherein the rock mass model includes a three-dimensional geo-spatial representation of a material property of the rock mass.

7. The system of claim 1 , wherein the electronic processor is configured to estimate the drilling index for the hole based on a design of a drill bit of the first industrial machine.

8. The system of claim 1 , wherein the live loading data includes measurements collected by the secondary industrial machine during an interaction between the secondary industrial machine and a blasted rock mass material, and wherein the measurement includes a particle sized of the blasted rock material.

9. The system of claim 1 , wherein the electronic processor is configured to update the rock mass model based on drilling data previously-collected by the first industrial machine before the live drilling data is received.

10. The system of claim 1 , wherein the rock mass model includes a distribution of a material property for the rock mass, and wherein the distribution includes an estimated material property at a location within the rock mass and an uncertainty value associated with the estimated material property.

11. A system for estimating a hardness of a rock mass, the system comprising:
an electronic processor configured to
receive a rock mass model including parameters related to the rock mass located in a specified area,
receive live drilling data from a first industrial machine,
update the rock mass model during operation of the first industrial machine based on the live drilling data,
estimate a drilling index for a hole based on the updated rock mass model,
set a blasting parameter for the hole based on the estimated drilling index,
receive live loading data from a second industrial machine configured to collect blasted rock mass material, the live loading data including a digging energy; and
update the rock mass model based on the live loading data from the second industrial machine.

12. The system of claim 11 , wherein the live loading data includes indirect measurements collected by the secondary industrial machine during an interaction between the secondary industrial machine and a blasted rock mass material, and wherein the measurement includes a particle sized of the blasted rock material.

13. A system for estimating a hardness of a rock mass, the system comprising:
an electronic processor configured to
receive a rock mass model including parameters related to the rock mass located in a specified area,
receive live drilling data from a first industrial machine,
update the rock mass model during operation of the first industrial machine based on the live drilling data,
estimate a drilling index for a hole based on the updated rock mass model,
set a blasting parameter for the hole based on the estimated drilling index,
receive live loading data from a second industrial machine configured to collect blasted rock mass material, the live loading data including a motion through a dig face; and
update the rock mass model based on the live loading data from the second industrial machine.

14. The system of claim 13 , wherein the live loading data includes indirect measurements collected by the secondary industrial machine during an interaction between the secondary industrial machine and a blasted rock mass material, and wherein the measurement includes a particle sized of the blasted rock material.
