Pacing out stockpiles is not a control measure.

Quarry drone operators and mineral planners need objective volumes for production, royalties, and Quarries Regs safety planning. Drone surveys make that monthly, cheap, and defensible.

Slow Walk-Over Stockpile Counts

Traditional tape-and-prism stockpile counts are slow and error-prone on anything other than perfectly conical piles. A drone flight resolves every stockpile to sub-2% against weighbridge tonnage in a single shift.

Noisy Weighbridge Reconciliation

Without an objective volume, production vs weighbridge is always a negotiation. A PPK-corrected drone survey is the referee — consistent, auditable, and accepted by both commercial and financial teams.

Quarries Regs Safety Planning

The Quarries Regulations 1999 demand risk-assessed faces, tips, and lagoons. A drone survey gives the quarry manager the geometric evidence the safety plan needs — without sending anyone near the crest.

The Quarries Regs and RIDDOR don't care about the drone.

A quarry is a statutory workplace under the Quarries Regulations 1999. The drone operator has to fit into the site's permit-to-work system, Mines Inspector-ready documentation, and RIDDOR reporting chain.

Every quarry survey on this network is flown by drone operators who coordinate with your quarry manager, publish accuracy statements, and supply survey data directly compatible with your geotechnical and safety paperwork.

The result is a volumetric and geometric dataset that stands up in HSE inspection, royalty reconciliation, and insurer audit — and makes your monthly production meeting shorter.

Quarries Regs-Aware Operations

PDRA01 & £5M Public Liability

Outputs your commercial team can sign off.

Our network operators deliver survey-grade outputs ready for production reporting, weighbridge reconciliation, and Quarries Regs safety files.

Volumetric Reports

Extraction, stockpile, and void volumes against last month's surface, reconciled against weighbridge tonnage typically inside 2%. Delivered with accuracy statement and GCP log — ready to drop into your production MIS.

Stockpile Inventories

Separated, classified, and dated volumes per product and per stockpile. End-of-year audit becomes a five-minute comparison to the last flight, not a site-wide pacing exercise.

Safety-Plan Geometry

Face profiles, tip geometry, and lagoon freeboard captured to survey accuracy — the evidence base your Quarries Regs safety plan, geotechnical engineer, and HSE inspector all actually want to see.

Book your quarry survey in 3 steps.

Submit one brief. We aim to review it within one working day, then introduce relevant independent specialists who can assess the project.

01

Describe the Site

Tell us the extraction, the product mix, and the frequency required. Takes under two minutes.

02

Compare Specialists

We review the brief against relevant verified profiles and current availability. If listed supply is limited, we will say so and source availability manually. Any pilot introduced must confirm equipment, permissions, timing and deliverables for the actual job.

03

Fly & Report

Your drone pilot integrates with the site permit system, flies around blast and haul schedules, and delivers a volumetric pack ready for your production meeting.

Quarry Survey FAQ

Technical questions on reconciliation, safety planning, and operations.

How does drone volume compare to weighbridge tonnage?
With PPK-corrected data and proper GCP control, drone volumetric reconciliation against weighbridge tonnage routinely comes out inside 2%, sometimes better. The remaining variance is usually moisture and density assumptions, not the survey.
Can the survey inform a Quarries Regs safety plan?
Yes. Face geometry, tip profiles, and lagoon freeboard captured by drone give the quarry manager and appointed geotechnical engineer objective evidence the safety plan can reference directly. HSE inspectors are well used to drone-derived geometry in safety files.
What survey frequency do you recommend?
Monthly for active extraction, weekly for fast-moving stockpiles, and a full annual reconciliation flight at year-end. Most drone operators on the network run standing monthly contracts with a premium rapid-deploy rate for ad-hoc flights around blasts or incidents.
Can you operate around blasting and heavy plant?
Yes — network operators integrate with your site permit-to-work system, plan flights around blast windows and plant movements, and maintain banksman coordination throughout. Pre- and post-blast surveys are actually one of the more useful drone applications in an operating quarry.
