CAA-Approved Mining Surveys

Drone Mining & Open-Cast Surveys.

Compare quotes from specialist UK drone operators for monthly extraction volumetrics, slope-stability monitoring, haul road condition, and spoil-heap reporting — all delivered to survey-grade accuracy without a surveyor on the bench.

“Every drone pilot on this network is personally vetted by me — insurance, qualifications, flight history.”

You cannot manage an open-cast on quarterly numbers.

Drone operators still rely on slow total-station surveys that arrive too late to inform blast planning, haul cycles, or slope maintenance. Drones collapse that loop to hours.

Manual Volumetrics Are Too Slow

Total-station walks can take days, during which extraction keeps moving the ground under the surveyor's feet. A drone captures the entire pit inside a single shift with a denser point cloud than ground survey could ever deliver.

Haul Road Degradation

Rutted haul roads destroy tyre budgets and trigger incidents. A monthly orthomosaic gives the operations team an objective map of wear, sag, and drainage issues — targeting grader time exactly where it pays back.

Bench & Highwall Safety

Sending a surveyor to inspect a fractured highwall is exactly the exposure the Quarries Regs are meant to avoid. A drone puts survey-grade data in your geotechnical engineer's hands without anyone approaching the crest.

A mine is a live, dangerous environment with its own safety regime. The Quarries Regulations 1999 and MHSWR apply to the drone operator every bit as much as to anyone else on site — stand-off distances, PPE, and blast-time exclusions are not negotiable.

Every mining survey on this network is flown by drone operators who integrate with your site SHE system, coordinate around blasting schedules, and publish an accuracy statement alongside the volumetric.

The result is a dataset that feeds production planning, geotechnical assessment, and royalty reconciliation without creating fresh operational risk.

Site-Integrated Operations

PDRA01 & £5M Public Liability

Outputs your production team will actually use.

Our network operators deliver survey-grade data ready for geotechnical engineers, production planners, and royalty reconciliation.

Monthly Volumetric Reports

Extraction volume against last month's surface, stockpile inventories, and reconciliation against weighbridge tonnage. Delivered with accuracy statement and GCP log, ready to drop into your production MIS.

Slope Stability Data

PPK-corrected point clouds flown at consistent GSD let your geotechnical engineer measure bench movement between flights to better than 3 cm — a genuinely useful early-warning dataset for highwall assessment.

Haul Road & Spoil Reports

Annotated orthomosaics of haul road wear, drainage, and spoil-heap geometry. Grader, pump, and tipping plans targeted by objective data, not subjective walk-rounds — with a dated record for the manager's monthly report.

"We shifted from quarterly total-station surveys to a monthly drone rota. The volumetric uncertainty dropped, the report hit the planning meeting on time, and our reconciliation against weighbridge tonnage improved noticeably."

Mine Surveyor, Kirkby-in-Ashfield

"Highwall movement monitoring used to mean exposing a surveyor to a potentially unstable crest. Now we get a PPK point cloud every month and I can track millimetre-scale movement from the office. Huge safety and data win."

Fiona D.

Geotechnical Engineer, Aberdeen

"Haul road wear was subjective for years. The annotated orthomosaic now tells our grader gang exactly where to deploy on Monday morning. Tyre spend is already trending down."

Mining Survey FAQ

Technical questions on frequency, safety, and accuracy.

How often should extraction volumetrics be flown?

Monthly is the baseline for most operating open-cast sites — that matches the production and royalty reporting cycle. Weekly flights are justified on active stockpiles where tonnage moves fast, and quarterly is usually enough for low-activity dormant cells.

Can drones reliably assess slope stability?

PPK point clouds flown at consistent GSD let a geotechnical engineer measure bench and highwall movement between flights to better than 3 cm. Drones don't replace rigorous slope instrumentation, but they give a far wider-area overview than a handful of inclinometers ever will.

Will drone flights interfere with blasting or plant movement?

No — drone operators plan flights around your blast roster and haul cycle. Pre- and post-blast flights are actually a great use of drones, giving your blast engineer an objective fragmentation and heave record. All flights happen inside site SHE permits with banksman coordination.

How does drone volumetric accuracy compare to total-station?

With proper ground control and PPK processing, drone volumetrics match total-station accuracy for bulk earthworks inside 1–2%, across a vastly denser surface. For a fast-moving pit that's a better dataset than a total-station sample pattern could ever capture within the same time window.
