Triangulation
A technique involving the measurement of triangles to map out the area of interest. Commonly used for establishing control networks.
Leveling
The process of finding the elevation of points or establishing points at a given elevation.
GPS Surveying
Uses Global Positioning System to determine accurate locations. Useful for wide area surveys and real-time applications in mining.
Hydrographic Surveying
The measurement and description of bodies of water within and around a mine to ensure safe water management.
Laser Scanning
A method to quickly capture the surface geometry using laser light. Often used for high-precision mapping.
Total Station
An electronic/optical instrument used for angle measurement, distance measurements, and coordinate readings in mining.
Underground Surveying
Adaptation of surface surveying techniques for the mining environment where GPS is not available.
Theodolite Surveying
A technique where a theodolite is used to make precise measurements of angles in the horizontal and vertical planes.
Electronic Distance Measurement (EDM)
Technique using electronic instruments to measure distances between points.
Volumetric Surveying
Calculating volumes of stockpiles or excavated areas to monitor and manage mine production.
Control Surveying
Establishing reference points to use as a base for future surveying activities within mine sites.
Photogrammetry
Creating measurements and maps from photographs, used for planning and monitoring mine progress.
Aerial Photogrammetry
The use of drone or aircraft photography to create maps and 3D models of mine sites.
Mine Surveying Software
Software solutions that bring together data from various surveying instruments to create comprehensive mine maps and models.
Perspective Grid Method
A plot of the mine workings viewed from above, used for visually representing spatial relationships in underground mining.
Convergence Measuring
Technique to measure the closure or opening of underground openings to monitor stability.
Stope Surveying
Surveying method focused on the measurement and evaluation of ore body removal in open stopes.
Benchmarking
Establishing points of known elevation and position to serve as references within the mine.
Cross-Section Surveying
Creating cross-sectional profiles perpendicular to the mine trend to detail the underground topography and geology.
Time Domain Reflectometry
A technique using the time difference between emitted and reflected electromagnetic waves to measure distances.
Seismic Surveying
Using the reflection or refraction of seismic waves to map geological structures.
Slope Monitoring
Assessing slope stability using techniques like laser scanning, radar systems, and prism monitoring to prevent landslides.
Geodetic Surveying
Surveying that takes into account the curvature of the earth to obtain precise measurements over large areas.
Pit Design Surveying
Specialized surveying to create an optimal pit design by defining the most economical limits of the pit.
Rescue and Recovery Surveying
Surveying techniques adapted for use in emergency situations, such as post-disaster mapping and rescue planning.
