Mine surveyors are responsible for maintaining an accurate plan of a mine as a whole and will update maps of the surface layout to account for new buildings and other structures, as well as surveying the underground mine workings in order to keep a record of the mining operation.
The surveyor has to measure and calculate volumes of ore from the mining operations as well as the volume of the dumps.
He can literally be called the resource manager.
The surveyors role means therefore that he has to do a lot of measuring in order to come up with maps of a mine site both above ground and below in order to optimize the mining process and he needs reliable equipment to perform this task accurately. Surveying has gone beyond the ubiquitous theodolite and todays surveying relies heavily on technology to provide accurate maps of the topography with safety and speed in mind. To measure distances lasers are now used which offer safety and accuracy while wall mounted prisms enable the surveyor to make fast and accurate calculations from a comfortable position. Robotics also mean additional safety because remote controlled equipment means the surveyor doesn’t undertake unnecessary risks. Today’s equipment is also able to integrate with software such as AutoCAD in order to offer the surveyor the ability to produce 3D mine designs while superimposing measurement data on the design layout. In this issue we take a look at what else is out there in the market today and the new breakthroughs that technology is offering this age old profession.

GIS software lets you produce maps and other graphic displays of geographic information for analysis and presentation. With these capabilities GIS is a valuable tool to visualize spatial data or to build decision support systems for use in your organization. A GIS stores data on geographical features and their characteristics. The features are typically classified as points, lines, or areas, or as raster images. On a map, mining data could be stored as points, road data could be stored as lines, and boundaries such as natural resource fields could be stored as areas, while aerial photos or scanned maps could be stored as raster images. GIS stores information using spatial indices that make it possible to identify the features located in any arbitrary region of a map
Maptitude implements a professional-strength relational database, a feature critical for GIS software. Attribute data may be freely joined to and detached from geographic layers and tables. Relational data manipulation is integrated with robust and powerful geo-processing for spatial queries, polygon overlay, and other location based analyses.

SBL Infotech Uk Ltd
Unmanned Aerial Vehicles (UAVs) are big news at the moment. This will only increase in the future. Indeed some mining companies have already turned to UAVs as an alternative survey method.
First and foremost UAVs uniquely fit for the purpose of mining clients. Virtually all mine sites suffer from the challenges that UAVs are designed to solve. These challenges play to the strengths of UAV technology which are portability- UAV equipment can be transported quickly, at short notice, between countries, greater accessibility to difficult terrain, increased mobilisation speed, reduced dependence on ideal weather conditions and wider range of applications.
In turn these strengths offer a number of benefits over more traditional survey methods for instance cost prohibitive projects become cost effective, unfeasible projects become feasible, issues around preferred accuracy are negated – typically clients can expect a horizontal and vertical accuracy of less than 10cm – and corporate Social Responsibility. The savings and output accuracy provided by UAVs have allowed mining companies to extend the areas of coverage to include other local terrain. The mapping database can then be shared with local communities.
So far SBL has supplied their UAV Services to clients in Ghana, Nigeria, Sierra Leone and Congo.
3D MSI specialize in underground mine surveying and 3D modelling of survey data, using laser scanning instrumentation and if required a specially designed remote surveying vehicle (RSV) to survey underground operations at high speed. 3D MSI use the captured data to provide three dimensional models to document as-built environments to their clients’ specification. The models can be presented as either traditional 2D plan and sectional drawings or 3D format, or both.
According to 3D MSI’s strategic development manager, Nigel Hewitt their products fit well in the African mining industry in that they specialize in working in challenging physical environments, typical of pioneering new and existing mines, or mines that have been abandoned and are being re-assessed for profitable mining.
Using cutting edge, laser scanning technology, 3D MSI can provide accurate and pin-point precision models of working or planned working environments. Their specialism in the field of 3D laser scanning puts them at the forefront of modern surveying methods. From initial scanning of the mining environment, through to the subsequent processing of millions of data points, they can generate precise and comprehensive 3D models of as-built environments at speed.
Reflecting on the value they are able to add, the Company’s founder, Dr James Jobling Purser, added that while a great deal of money is often spent adjusting excavations that deviate slightly from original designs, 3D MSI can reduce this need by more quickly providing a comprehensive analysis to clearly demonstrate levels of deviation from a design before a tunnel or excavation is fitted out with services and equipment. The speed and accuracy of scanning allow 3D plans to be created providing design engineers with definitive plans of the operation to work from rather than limited line drawings.

The company from Trondheim, Norway has developed a range of top quality instruments including directional core barrel, core orientation equipment, and both magnetic and non-magnetic downhole survey instruments. Using these technologies, their clients reach their targets while reducing drilling costs. Today, Devico is the global market leader in providing directional coring services directly, and via its network of exclusive agents and subsidiaries.
According to Devico’ business development manager Ben L’Heureux currently their company is focusing on Africa since they have their own agent Devico South Africa. Ben added that their unique system Devidrill use for directional core drilling is the most advanced feature of its kind. Devico provides directional core drilling and helps reduce the amount of drilling with a mother hole drilling program and can often save over 50% of the exploration time.
To provide top qualified directional core drillingservices to the drilling industry Devico and its subsidiaries Devico South Africa have established an international group of expert field engineers that supervise directional projects around the globe. Devico South Africa execute projects all around Africa and help reduce drilling costs, hit targets, save time and maximize budgets.
Their engineers also work with the project geologists to prepare and optimize drilling plans. They can suggest the depth where directional drilling should be started, and calculate how long the correction needs to be to aim the hole towards the target.
When professionals in the mining industry started to use borehole survey tools on regular basis approximately 40 years ago, they became aware of borehole deviation. They discovered that most of the holes ended up far from where they were planned.
Evorelution is a fully featured open-pit scheduling software solution that has assisted dozens of clients in creating practical, high-value schedules for the life cycle of a mine. Now the software has gone to the next level with Version 3.0 thanks to the addition of industry leading dynamic haulage optimization, and a new strategic scheduling capability that optimizes cut-offs to maximize NPV. Evorelution v3.0 is the only commercial solution that can dynamically create a production schedule with optimal fleet haulage routes, waste dump optimization including haul cycle-times and productivities, which managing director Steve Craig says is a significant product offering.

They are exceptionally easy to use and Maptek provides a range of training courses to quickly bring novices up to speed, and to ensure that advanced users keep abreast of developments. Responsive telephone, online and onsite support and consulting mean that the operational flow is not interrupted. Companies with mining at different sites benefit from having the same systems in use across their operations, as centralised planning can increase productivity and profitability, and personnel can move easily between sites.
Further time savings and safety benefits are realised by mounting I-Site laser scanners to site vehicles. The ruggedized, shock-absorbing system incorporates GPS, registration and back sighting routines.
I-Site software provides user-friendly scan processing and modelling tools with mining workflow built in. Specialised tools allow geologists and geotechnical engineers to analyse structures and surfaces. I-Site data can be visualised and manipulated using Maptek Vulcan mine planning software, with survey data fed directly into Vulcan for updating design and geological block models.
Maptek provides support and training for I-Site laser scanning systems throughout Africa from offices in South Africa and the UK. Expert technical staff can conduct site surveys, delivering data and customised reports in a timely manner.
Altus Positioning Systems provides today’s GIS engineers and surveyors with first class GPS/GIS products that are rugged and versatile for any work environment, compatible with most GIS software products, and supported by unmatched reliable one-on-one quality customer service.
The APS-T is a perfect fit for surveying in the mining industry. It features a high precision GNSS satellite receiver with embedded L-Band capability designed to provide seamless TERRASTAR D 10 cm positioning to the surveying market.
Integrated with state-of-the-art technology, the APS-T provides surveyors with a product that automatically utilizes Precise Point Positioning algorithms with L-Band corrections for decimeter level positioning.
For extending capabilities, the APS-T is fully upgradeable to a GPS + GLONASS RTK rover. Simple and easy to use, the APS-T is completely conﬁgurable from the data collector via Bluetooth or serial cable.
Clement Ogaja, GNSS Support Engineer at Altus says, “The APS-T is unique for African environment especially for regions lacking local real-timeGPS/GNSS network subscription services. With the APS-T it is possible to achieve 10 cm positioning with the L-band corrections, without a local base receiver or RTK network connection, and if there is need for higher accuracy, it is upgradeable to a RTK rover.”
