Drones are revolutionizing the mining industry, providing a new way to collect data and analyze haul roads in open pit mines. By using UAS technology, mining companies can gain a more comprehensive understanding of road conditions, identify areas of wear and tear, and improve safety and efficiency.
This article covers the technical details of how drones are used for haul road analysis. We will cover the key steps involved in planning and executing a drone flight, as well as the software and hardware required to process the data collected. We will also discuss some of the benefits of using drones for haul road analysis, and provide some examples of successful implementations in the mining industry.
Benefits of Using Drones for Haul Road Analysis
There are many benefits to using drones for haul road analysis in open pit mines. Some of the key advantages include:
- Improved safety: Haul road analysis with a drone reduces the need for workers to go into hazardous areas. This improves safety and reduces the risk of accidents or injuries.
- Better data collection: Drones collect data more quickly and accurately than traditional methods. Therefore, mining companies get a more comprehensive understanding of road conditions, identify areas of wear and tear, and can improve maintenance planning.
- Cost savings: Drones are more cost-effective than traditional methods, such as hiring surveyors or using heavy machinery. Drones cover large areas quickly, reducing the need for manual labor and saving time and money.
- Increased efficiency: By providing a more detailed understanding of road conditions, UAS technology helps mining companies to optimize their operations and reduce downtime. In turn, this improves efficiency and productivity.
Successful Implementations of Drone-Based Haul Road Analysis
There are many examples of successful implementations of drone-based haul road analysis in the mining industry. One such example is the Boliden Tara Mines in Ireland, which used drones to analyze their haul roads and improve maintenance planning. By using this technology, the company was able to identify areas of wear and tear more quickly and accurately, and make repairs before they became a safety hazard.
Another example is the LKAB iron ore mine in Sweden, which used unmaanned aerial systems to improve traffic flow on their haul roads. By analyzing the data collected, the company was able to identify bottlenecks and optimize traffic routes, reducing congestion and improving safety.
Planning a Drone Flight for Haul Road Analysis
The first step in using drones for haul road analysis is to plan the flight. This involves identifying the areas that need to be analyzed, and determining the flight path or mission flight plan. It’s important to keep in mind legal regulations and safety protocols. Weather and wind conditions in the area are also important to monitor.
To plan the flight, mining companies can use specialized software such as Vision Aerial Flight Deck. This software allows users to create a flight plan by drawing a polygon around the area they want to map. They can also specify the altitude and camera angle of the drone, and select the type of camera they want to use (e.g. RGB, thermal, or multispectral).
Once the flight plan has been created, it can be uploaded to the drone and flown automatically. During the flight, the drone captures images or videos of the haul road. These images will form a map or 3D model of the area.
Hardware and Software Requirements
To use drones for haul road analysis, mining companies need to have the right hardware and software in place. This includes:
- UAS: Mining companies need to select the right drone for the job, based on factors such as flight time, range, payload capacity, and camera quality.
- Cameras: The quality of the camera used on the drone is crucial for accurate data collection. Depending on the goals of the analysis, mining companies may need to use RGB, thermal, or multispectral cameras. Some of the popular cameras used include the Workswell WIRIS Pro, FLIR Vue Pro, Sony RX1Rii, and MicaSense RedEdge-MX.
- Flight Planning and Post Processing Software: Mining companies need to use specialized software to plan the drone flight, monitor the drone during flight, and process the data collected. Some of the popular software tools used in the mining industry include Pix4D, RDOai, DroneDeploy, and Agisoft Metashape.
- Computers and Servers: To process the data collected by the drone, mining companies need to have access to powerful computers and servers. This allows them to stitch together images into a map or 3D model. Finally they can perform additional analysis or calculations as needed.
