Surveying

Surveying is the most essential part of planning. It is the primary and most effective method of Data Collection. We offer number of surveys which include Topographic Surveys, Cadastral Surveys, Route Surveys, Utility Surveys, Urban Planning/Property Surveys, DGPS Control Surveys and Engineering Surveys. We have latest technology and the team of survey expertise to accurately determining the two dimensional as well as three-dimensional positions of points and the distances and angles between them.

ADEGO is a complete end-to-end drone data collection provider. We collect, analyze, and distribute aerial data quickly and more cost-effectively than ever before.

At 1cm / pixel resolution, our drone surveying deliverables lead the industry in precision. Turn-around time can be as short as a few hours. Whether the project is a 100 mile pipeline inspection, mining volume calculation, or a vegetation / crop diagnosis our team can quickly and safely provide a UAV survey at a never before seen price-point.

Benefits of using drones in mining

Faster and easily-repeatable surveys at low cost

Capturing data with a drone is up to 30 times faster than with traditional land based methods and does not require the presence of a surveyor on site. You can easily collect the data yourself and at a frequency best suited to your site for rapid data turn -around. Changes between two surveys can be tracked and highlighted automatically. In the long term, the costs of surveying and monitoring are substantially reduced.

faster data collection

Improving worker and site-safety management

Drones allow you to survey parts of the mine or quarry that are normally difficult to access with traditional surveying equipment. This eliminates the hazards employees typically face while walking through dangerous zones, navigating active sites or climbing onto stockpiles. All this without disrupting the flow of operations and movement of machinery.

100%

safe surveying operations on site

Highly accurate measurements

By providing thousands of data points for one stockpile, drone surveys are far more accurate than surveying with total stations. All surface unevenness and undulations are identified. The surveys make it possible to reduce the deviation in stockpile volume calculations, to generate improved base files for stockpiling, and to produce more accurate financial statements and regulatory checks.

Applications in mining

Stockpile inventory and management

Since stockpiles are by nature irregular in shape and exhibiting craters, it is difficult to estimate their volume with great precision using traditional instruments such as ground-based measurements. These slow and costly methods also prohibit frequent surveys and can even threaten the surveyor’s safety climbing up and down the stockpiles or working in the middle of the machinery.

The cut, fill, net volume and area are instantly calculated once a shape is drawn over a stockpile, a trench or any other voluminous areas.

More and better data with drones survey

The drone aerial images can be used to generate a point cloud, digital surface model, digital terrain model and a 3D reconstruction of the site, including its stockpiles. As the point cloud contains several thousand data points, very accurate volume calculations can now be performed easily. You can now calculate the value of stockpiles for monthly reconciliations or year-end audits with high accuracy and thus improve the consistency of the inventory reports in the company’s balance sheet. You can also validate the amount of material moved by subcontractors as the drone results and postprocessing hardware are unbiased.

Multiple volumes can be measured at the same time. All measures can be exported in PDF reports.

More frequent data for monthly or weekly management

Given the speed at which inventory surveys can be conducted, frequent data collection is becoming cost-effective; be it weekly, monthly or quarterly. You can fly your site as often as you like. You do not need to wait for a semi-annual aerial survey. With these regular data collections, you improve inventory and operational management, while eliminating the risks associated with the surveyors working physically on the site.

Efficient, Accurate and Safe Data Capture

Mining operators who adopt drone technology quickly realize the significant added value it brings to their industry.

Namely, it improves the overall efficiency of large mine site and quarry management by providing accurate and comprehensive data of site conditions in a very short time. It also supports better coordination among teams onsite and internationally, offering dynamic oversight of all operations.

Above all, this data can be safely produced by on-site workers with minimal surveying experience at a fraction of the cost of traditional survey methods.

Drone data provides more precise volumetric measurements than traditional surveying methods, such as ground-based GNSS. This allows better valuation of stockpiles.

By using a drone, you produce easily and inexpensively images, 3D reconstructions and surface models for areas that are to be blasted or drilled.

These models are used to accurately analyze the area to be drilled and to calculate the volume to be extracted. These precise estimates will allow you to better manage resources such as the number of trucks needed. A comparison against surveys taken before and after the blasting will allow volumes to be calculated more accurately. This improves planning for future blasts, cutting the cost of explosives, time on site and drilling.

Workers’ safety is a priority on mine sites and in quarries due to their ever-changing nature. With the highresolution images from drones, you can inspect otherwise difficult-to-access or high-traffic areas of the site, without endangering yourself our any workers. Aerial images provided regularly by drones also help planners ensure that mine features, such as slopes, tailings dams, berm heights or safety rocks, meet safety standards and are not about to become a hazard.

Data Outputs

The data outputs of ADEGO are post-processing software agnostic, therefore compatible with any post-processing solutions and existing workflows.

Drone images are used to recreate a highly accurate orthomosaic map of the mining site or quarry. Each pixel contains 2D geo-tagged information (X, Y) and can be used for distance and surface measuleft/p>

Methodology

Phantom 4 RTK Flight for smaller areas around 100 – 300 hectors

3 double grid missions where executed concentrating the center part of the mine excluding the outer buffer area. This mission was conducted at a height of 70m for good GSD

Talon UAS Flight for big areas

A single flight of Talon with single grid was done over entire height at an altitude of 100m with 24MP camera. Thus covering the outer area and also adding more detail to the center point of the mine.
