Equipment and techniques used in mining and tunneling. Total stations are the primary survey instrument used in mining surveying. [citation needed] Underground mining. A total station is used to record the absolute location of the tunnel walls'', ceilings (backs), and floors as the drifts of an underground mine are driven.
Geological surveying is an important discipline of engineering concerned with land survey, exploration of mineral resources, and other aspects that affect the economic development of a country. Geological survey techniques include topographic mapping and geological mapping. Geological maps show the structure of the earth''s crust and are used for locating energy resources like petroleum, coal ...
GeoModel, Inc. has over 50 years of combined experience and the latest geophysical equipment to locate goldbearing deposits. Proper Geologic Knowledge and Good Geophysical Surveying can make the difference between success or failure of your gold mining operation.
Land surveying is a process which adopts both onsite and offsite techniques to measure and map a predetermined area. There are many types of land surveys and each way has its own benefits. It is important to determine which type of survey will be useful to your situation as different forms of surveys are required for particular projects.
(EDM) or laserranging equipment is employed for cavity measurement. It is the responsibility of the authorised mine surveyor to become . conversant with the survey methods that will achieve the standards of accuracy set out above. The choice of technique is a professional decision of the authorised mine surveyor, based on sound practice, and will
Surveying has been a focal point of evolution in technology joining mathematical applications to innovations in mechanical engineering and instrument construction technology. The original aims of a couple of surveyors has been realised through the International Institution for the History of Surveying and Measurement (IIHSM) – Permanent ...
Mining Surveying Mine surveyors are involved in very aspect of a new mining operation, this includes initial exploration, initial construction of mine operations, ongoing mining works and rehabilitation of site after mining is completed. Mining surveyors use various instruments including GPS, GIS, EDM and laser scanning, to make their

2 • Surveying has to do with the determination of the relative spatial location of points on or near the surface of the earth. • It is the art of measuring horizontal and vertical distances between objects, of measuring angles between lines, of determining the direction of lines, and of establishing points by predetermined angular and linear measurements.
Underground surveying is quite different from surveying on the surface. In tunnelling or mining operations it may be hot, wet, dark, cramped, dusty, dirty and dangerous, and usually most of these. The essential problem in underground surveying is that of orientating the underground surveys to the ...
Rugged hardware and specialised accessories combine with powerful modelling and analysis software to deliver a safe solution for underground survey applications.
