In the mining industry, large-scale blasting is a common method used to create cavities—known as stopes—where valuable ores are extracted. However, these stopes can become extremely unstable after blasting, with loose rocks the size of cars hanging precariously and posing serious risks.
The challenge lies in the fact that it's nearly impossible to accurately assess the conditions inside a stope. Traditional methods like lowering an inspection camera into a borehole or using a pole-mounted camera offer limited visibility and data, making it hard to determine the area’s stability, locate missed ore, or understand the cause of any blockages.
Enter indoor drones—game-changers for the mining sector. These advanced tools allow personnel to gather high-quality visual data from even the most hazardous and inaccessible areas. With this data, teams can generate 3D models and sparse point clouds, improving their understanding of the environment and enhancing safety, efficiency, and cost-effectiveness.
Here are six key benefits that indoor drones bring to modern mining operations:
1. **Safety**
Drones eliminate the need for workers to enter dangerous environments. For example, they can inspect stopes without exposing miners to falling debris or confined spaces. They can also check critical processing equipment like stockpile feeders, mills, flotation cells, and crushers without requiring human entry, significantly reducing risk.
2. **Cost Savings**
By identifying remaining ore, protecting expensive machinery, and reducing downtime during inspections, drones help mining companies save millions. One hour of downtime can cost up to $150,000, but drone inspections allow operations to continue uninterrupted.
3. **Access**
Unlike consumer drones, indoor drones are built to withstand harsh underground conditions. Their rugged design allows them to navigate tight spaces and avoid collisions, making them ideal for exploring areas that would otherwise be unreachable.
4. **High-Quality Data**
Drones capture detailed images and videos, often surpassing what human inspectors can achieve. The Elios 3, for instance, offers 4K video, real-time LiDAR mapping, and advanced lighting features, enabling precise analysis of stope conditions and equipment status.
5. **Efficiency**
With quick access to visual data, maintenance teams can perform spot checks and improve overall maintenance procedures. This leads to fewer unscheduled downtimes and better long-term planning.
6. **Data Localization**
New software like Inspector 4.0 allows users to pinpoint exact locations within a mine, making it easier to revisit specific areas for further investigation or follow-up actions.
Indoor drones are not just a technological upgrade—they're a transformation in how mining operations function. They make mining safer, smarter, and more sustainable, paving the way for the future of the industry.
