Webinar Summary- Strayos Under the Hood: The Engine Driving the Mine to Mill AI

Mining is the perfect industry to leverage the power of AI. It produces mountains of data everyday from site operations and can realize significant value from using AI. However, implementing AI can be intimidating. Many people still view it as a “black box”. So, to help, Strayos is pulling back the curtain and sharing with you how the AI magic is made.

Join Strayos experts Ravi Sahu & Brad Gyngell as they discusses how AI can help realize some of the biggest opportunities in the drilling, blasting, and mining industries, and how it can help mines achieve a more sustainable future.


  • How to prepare data for a successful AI pipeline
  • What it takes to develop an accurate industrial grade AI model
  • Dig Deeper AI Applied: Rock Mass Characterization, Fragmentation, & Pit Optimization
  • How the AI feedback loop unlocks hidden insights
  • Using AI-powered Scenario Analysis to better plan the future
  • How to 10x your mine's output using AI in your workflow

We'll start at the end...

Unfortunately we ran out of time before we were able to answer everyone's questions. So, as promised, here are the answer to the questions asked during the webinar...

1. What is the accuracy of fragmentation prediction from whole blasted muck pile?
The accuracy of the fragmentation prediction on a blast muck pile depends upon few different factors:

  • Accuracy in data and imagery collection - The better the pixel resolution the more accurate the edge detection results. Our best practices guidelines describes some of the ways to improve data collection.
  • Data analysis and AI detection: AI detection for rock sizes utilizes pixel based segmentation and it has been compared and verified with ground truth data such as manual scale measurements and placing golf balls in blasted muckpile.

2. How the joints extends inside the rock mass is confirmed, many times bench faces are not cleaned or filled with dirt's?

With visual RGB photo data such as drone 3D model several key bench features using RockMass AI can be detected such as Joints, bedding blane, strike and orientation.

In order to see the bench faces which are filled with dirts - different type of sensing solutions can be used such as Lidar and Hyperspectral sensors.

3. Can this data be integrated into MineStar or Modular gravity calculations to help with reporting accuracy?

Yes, Strayos generates variety of industry standard file format and it can be exported to 3rd party applications including Minestar.

4. From your experience what % of boulder material can be allowed for secondary breakage before considering for redesigning of blast design parameters, for optimization

The % of boulder material is subjective to the type of operations and plant processing setup. In order to consider any blast optimization KPIs. Whole upstream and downstream workflow needs to be understood to make any design parameter changes.

5. Is there a risk that AI could make humans less intelligent or get used by people that would not have the common sense to know the answer from AI may be wrong? I think of an exercise years ago where my students were going of there tablet GPS and I had to say I do not care what the tablet GPS says. The sun rises in the east and set in the west and you are heading in the wrong direction. This does not mean I do not believe in AI as being good but what type of safe guards are needed or can we use? I like to use a statistical method called the null hypothesis before I accept the answer.

We believe AI is just a decision making tool with speed and scale. It empowers human to run what if scenarios and consider all the parameters to ensure the associated impact from that decision. The future we believe is where Artificial Intelligence(AI) will absorb mundane tasks and as a result human intelligence (HI) could thrive with their talent on innovation and creativity.

6. How can your models used to ensure grade variability is minimal?

Our hyperspectral sensor AI models can be applied to detect grade variability across the site, the rock bench or the muckpile. This can be used to minimize the grade variability entering the processing plant by enabling selective mining operations in the planning, blasting and loading phases.

7. How do you incorporate the right explosive consumption in the AI system to help in blast? What about the grade variability prediction?

The incorporation of right amount of explosives is subjected to several variables such design pattern, geology, rock mass, desired fragmentation, equipment's used in operations and crusher throughput requirements etc. Al can consider all the variables and further calibrate to specific site to arrive at right amount of explosive consumption.
