Drone Survey for Mining & Aggregate Operations
Flooded pit depth, stockpile inventory, and dewatering volumes — measured without putting a crew on the water or on the pile, and without pausing production.
Know Your Pit.
Without Putting Anyone In It.
Flooded quarry pits are among the most hazardous environments in mining operations. Getting accurate depth, volume, and sediment data from them traditionally meant dive teams or boat-based sonar — both slow, expensive, and genuinely dangerous.
Northern Drone flies a drone-mounted echo sounder over flooded quarry pits, returning depth to ±1 cm with RTK positioning. You get color-coded depth maps, cross-section profiles, full point clouds, and CSV exports with Easting/Northing/Z-values — everything needed for dewatering planning, reclamation permitting, sediment management, and extraction decisions. No personnel in the water. No operational downtime.
Commercial diving is among the most hazardous occupations — fatality rates orders of magnitude above general industry. Flooded quarry-specific risks include near-zero visibility, submerged highwall slumps, thermoclines, entanglement, and differential pressure at pump/intake structures (a leading cause of fatal commercial diving incidents in inshore environments per ADCI/OSHA).
Dual-frequency sonar (200 kHz / 50 kHz) maps both the sediment surface and the hard bottom beneath — sand, clay, or rock. A documented quarry case study (SPH Engineering / Knife River, Texas, 2024) detected sediment layers to 30+ ft depth in a single survey day with no personnel in the water.
MSHA (30 CFR Parts 56/57) requires accurate mine maps, hazard assessments, and rapid reporting of unplanned flooding. State reclamation authorities frequently require volumetric data for permit compliance. Our georeferenced deliverables are formatted to support these reporting requirements directly.
Sediment accumulation rates, water level changes, and pit geometry shifts are only visible with repeat surveys. We can return quarterly, annually, or after major events to build a longitudinal record of your water asset — enabling proactive management before issues affect operations or compliance.
Every bathymetric survey includes: color-coded depth contour map with isolines, cross-section profiles, georeferenced point cloud, CSV export (Easting / Northing / Z-Value), and volume calculations. All data is GIS-ready and formatted for your engineering team, reclamation consultant, or regulator.
Map Your Pit. No Dive Crew Required.
One survey day. No personnel in the water. Complete depth, volume, and sediment data ready for your engineering team within 72 hours.
