Drone Data Collection and 3D Modeling for Blast Sites
Optimizing blast performance begins with accurate drone data that can be transformed into detailed 3D models. Let’s dive into how drones and 3D modeling turn raw data into actionable insights for blast site management.
Drone Technologies for Data Collection
Drones equipped with tools like photogrammetry and LiDAR are revolutionizing how data is collected on blast sites. Photogrammetry captures overlapping images to map surface conditions and terrain, while LiDAR goes a step further by penetrating vegetation to render highly detailed topographic data. For areas that are tough to access, aerial 360° imagery adds another layer of clarity to site documentation.
One of the biggest advantages? Speed. Drone surveys are over 20 times faster than traditional ground methods, allowing mining operations to gather comprehensive data without disrupting daily workflows. Even better, the processed data is often ready within 24 hours.
"The site map can be updated every day – if not multiple times a day." - Ravi Sahu, CEO of Strayos
These advanced data collection techniques lay the groundwork for virtual blast design and ongoing performance monitoring.
Steps to Create High-Resolution 3D Models
The process of creating detailed 3D models starts with drones capturing overlapping images. Software like DJI Terra and Pix4D then processes these images into 2D orthomosaics and 3D terrain models. By analyzing shared points across multiple images, the software calculates precise spatial relationships.
To ensure the highest level of accuracy, ground control points (GCPs) are strategically placed across the survey area. These points anchor the digital models to real-world coordinates, providing centimeter-level precision critical for blast optimization.
During processing, the raw drone data is converted into a variety of products, including geotagged 3D maps and models like Digital Elevation Models (DEM), Digital Terrain Models (DTM), and Digital Surface Models (DSM). Each of these models serves a specific role in blast analysis and planning.
High-resolution aerial imagery combined with photogrammetry captures intricate details of benches, ramps, and walls, all georeferenced to survey-grade accuracy. This depth of detail allows engineers to pinpoint potential issues, plan drill hole locations, and fine-tune blast patterns with greater precision.
Recording Pre- and Post-Blast Conditions
Pre-blast data plays a crucial role in designing safe and efficient explosive plans. It provides engineers with the foundation to select the right explosives and design blasts that maximize productivity while adhering to safety standards.
By comparing pre- and post-blast models, engineers can evaluate the effectiveness of their designs and make adjustments for future improvements. These evaluations are critical for analyzing changes in factors of safety (FoS) and identifying potential slope stability concerns.
Once 3D models are created, they become the basis for detailed assessments. Pre- and post-blast 3D models help engineers measure mineral extraction volumes, analyze muck pile dynamics, and evaluate fragmentation metrics.
Post-blast analysis goes further by visually assessing muckpile shape, back damage, distribution, and fragmentation. Drones also provide precise measurements of pile volume and fragment size, offering quantitative data to refine future blasts.
Another major advantage of drones is their ability to safely record blasts from hard-to-reach locations. This footage gives engineers a clearer understanding of blast dynamics and highlights areas for improvement.
"Using a drone for perimeter security is to help the people in charge get people out of the hazardous blast zone. Not only by radio and phone but by aerial video for better oversight too. This brings an added value to the process that ensures better control." - Alexander
Monitoring changes in factors of safety (FoS) and assessing slope stability after blasting are essential for preventing accidents and maintaining safe operations.

Digital twins have revolutionized how engineers analyze blast performance, turning what was once an educated guess into a precise science. These tools allow for real-time monitoring, enabling engineers to measure how effective explosive designs are and make data-driven improvements. The following sections dive into the methods used for post-blast evaluations and how digital twins drive ongoing improvements.
Techniques for Post-Blast Monitoring
Modern digital twin platforms leverage AI-powered computer vision to analyze blast results with impressive precision. Drones equipped with high-resolution cameras capture detailed images of muck piles immediately after a blast. This imagery is then processed by machine learning algorithms to measure fragment sizes, assess pile geometry, and analyze material distribution patterns.
The process starts with 3D photogrammetry reconstruction. Drones collect thousands of images from various angles, which are stitched together into accurate 3D models of the post-blast site. These models allow engineers to measure changes in bench geometry and serve as the basis for detailed fragmentation analysis.
Using AI-based image processing, the system automatically determines fragment size distribution and evaluates the shape and volume of muck piles. This data is critical for optimizing future blasts.
Real-time monitoring during the blast itself adds another layer of insight. Specialized cameras and sensors track throw velocity, fragmentation patterns, and material displacement as the explosion occurs. These metrics validate simulation predictions and enhance the accuracy of digital twin models.
At Gold Fields' St Ives gold mine in Western Australia, this advanced approach to monitoring paid off in a big way. By optimizing blasting based on high-resolution data and simulations, the mine achieved smaller, more uniform fragments, eliminating the need for primary crushing. This adjustment cut energy consumption by 8% and increased mill recovery rates simultaneously.
Comparison of Drone-Based vs. Standard Methods
Drone technology has proven to be a game-changer compared to traditional ground-based methods. It offers faster, safer, and more accurate blast monitoring, making it an increasingly popular choice for mining operations.
| Survey Method | Survey Duration | Measurement Accuracy | Personnel Needed | Safety Incidents (per 100 surveys) | Operational Cost | Data Output Type |
|---|---|---|---|---|---|---|
| Traditional Ground Surveys | 3-7 days per 247 acres | 4-12 inches (2D, limited 3D) | 4-8 surveyors | 2-5 (hazardous terrain exposure) | $10,000–$15,000 per large site | 2D maps, basic 3D models |
| Drone-Based Surveys | 1-3 hours per 247 acres | 0.8-2 inches (accurate 3D models) | 1-2 operators | <0.1 (minimal personnel risk) | $2,000–$5,000 per large site | High-res 2D/3D maps, point clouds, orthomosaics |
The time savings alone are staggering. Drones can survey up to 247 acres in just a few hours, collecting thousands of data points per minute. This speed allows for near-instant analysis, enabling quicker decisions for the next steps in the operation.
For example, Granite Construction used drones for volumetric stockpile measurements and achieved comparable accuracy to traditional methods in a fraction of the time. Their volume calculations were within 1% of alternative methods.
Safety is another major advantage. Ground surveys often expose workers to hazardous post-blast conditions, such as unstable terrain and loose rock. Drone-based monitoring eliminates this risk, reducing safety incidents from 2-5 per 100 surveys to less than 0.1.
