Mining in focus Mine surveyors at an opencast mine. The importance of mine surveying Mine surveyors form a critical link in the day-to-day functions of any mining operation, writes Dr Nicolaas C. Steenkamp. [24] MINING MIRROR APRIL 2018 A s the old saying goes: “If you cannot measure it, you cannot manage it.” This is especially true on mines where daily, weekly, and monthly measurements of mined tons and advance meters are critical. This function is performed by mine surveyors who form a link between the different departments at any mine. Mine survey information is used by geologists, rock engineers, mining engineers, the environmental department, and management, to name a few. Mine surveyors also assist with infrastructure and are even used in some of the social responsibility projects undertaken by a mining company. Surveying is done for both surface and underground mining. The main task is to gather quality measurements, which are then used to generate maps or feed into other databases for use. Various requirements are set throughout the world to work as a mine surveyor, but generally it requires a tertiary qualification followed by vocational training, profession certification and registration, and continued education to s tay abreast of the rapidly changing technological advances in the surveying field. In South Africa, all qualified professional surveyors, technologist surveyors, technician surveyors, and GISc Practitioners have to be registered with the South African Geomatics Council (SAGC), previously known as PLATO. In the country, mine surveyors are appointed in terms of the Mine Health and Safety Act to oversee surveying, mapping, and mine plans at the mine. Quality of maps A mine surveyor should ensure that he/ she uses instruments and equipment of a precision equal to current best-in- industry standards and technology. The person doing the survey should ensure that all work is done in accordance with good engineering practices. Finally, the survey generally needs to have an accuracy of not less than 1:5000, depending on the final application. The datum station established as the origin of the survey needs to be stated on the map. This datum is
