Abstract

A process for improved blast design including the steps of: acquiring geological data about a blast site from multiple data sources; extracting one or more blastability labels from the geological data; mapping the blastability labels in two or three dimensions; designing a pattern of blast holes based on the mapping; designing explosive for each blast hole based on the blastability label for that blast hole; loading each blast hole in the pattern of blast holes with the designed explosive for that blast hole; and detonating the explosive. Also, a method of extracting valuable resources from an area using the process and a visualisation tool for blasting operations that displays data from the process.

First claim

The invention claimed is:

1. A process for improved blast design including the steps of:
acquiring geological data about a blast site from multiple data sources;
extracting one or more blastability labels from the geological data;
mapping the blastability labels in two or three dimensions;
designing a pattern of blast holes based on the mapping;
designing explosive placement for each blast hole based on the blastability label for that blast hole;
loading each blast hole in the pattern of blast holes with the designed explosive for that blast hole; and
detonating the explosive,
further including smoothing the mapping of labels to simplify the grouping of blastability labels within blast holes and between blast holes.

2. The process of claim 1 wherein the multiple data sources are selected from:
geophysical measurements such as conductivity, resistivity and magnetic susceptibility;
mechanical properties such as drill rotation speed, weight on bit, and pull down pressure;
and physical hole measurements such as diameter variation, orientation/deviation and temperature.

3. The process of claim 1 wherein the step of extracting one or more blastability labels from the geological data is done by machine learning.

4. The process of claim 1 wherein the step of designing a pattern of blast holes based on the mapping includes optimising the pattern of blast holes for efficacy of blast.

5. The process of claim 1 wherein the process is recursive with data from the step of detonating the explosive being used in the step of acquiring geological data.

6. The process of claim 5 further including the step of extracting data from the step of detonating the explosive to a data store for further analysis.

7. The process of claim 1 further including a step of a user inputting available data through a user interface.

8. A visualization tool for blasting operations at a mine site, the visualization tool comprising:
a graphical user interface displaying an image of a blast area in the mine site that is able to be manipulated in multiple dimensions;
an overlay on the graphical user interface that displays blastability labels and rock properties; and
a user interface tool permitting manipulation of the graphical user interface and overlay to change one or more of: angle of view; zoom level; explosive type; blast hole spacing, wherein the user interface tool permits a user to view a horizontal slice of a blast area.

9. A visualization tool for blasting operations at a mine site, the visualization tool comprising:
a graphical user interface displaying an image of a blast area in the mine site that is able to be manipulated in multiple dimensions;
an overlay on the graphical user interface that displays blastability labels and rock properties; and
a user interface tool permitting manipulation of the graphical user interface and overlay to change one or more of: angle of view; zoom level; explosive type; blast hole spacing,
wherein the user interface tool permits a user to view variation by depth in a cross-section of a blast area.
