In an open-pit mine or quarry, anaerial survey refers to the use of a drone equipped with an RGB camera payload to capture images from different vantage pointsof a site. Further images are processed in photogrammetry software which recreate geo-referenced 3D maps; contour lines, digital terrain models (DTMs) and digital surface models (DSMs) of the mining site. Mining professionals can also easily extract the precise volume of stockpiles or areas to be excavated, road boundaries; widths; crests; slope, length, and elevation change. Beyond this, drone surveillance can also help in a safety inspection.
Drones in the mining sector improve the overall efficiency of the large mine site and quarry management by providing accurate and comprehensive data detailing site conditions in a very short time.
Typical tasks in the mining sector:
• Stockpile management
• Mine Monitoring & Operation Planning
• Mining exploration
• Assessment before and after drilling or blasting
Benefits of using drones in mining:
• Highly Accurate Geometric Measurements
• Fast, repeatable mining survey
• Site Safety Management
