StarStarStarStar

Triangulation

StarStarStarStar

A technique involving the measurement of triangles to map out the area of interest. Commonly used for establishing control networks.

StarStarStarStar

Leveling

StarStarStarStar

The process of finding the elevation of points or establishing points at a given elevation.

StarStarStarStar

GPS Surveying

StarStarStarStar

Uses Global Positioning System to determine accurate locations. Useful for wide area surveys and real-time applications in mining.

StarStarStarStar

Hydrographic Surveying

StarStarStarStar

The measurement and description of bodies of water within and around a mine to ensure safe water management.

StarStarStarStar

Laser Scanning

StarStarStarStar

A method to quickly capture the surface geometry using laser light. Often used for high-precision mapping.

StarStarStarStar

Total Station

StarStarStarStar

An electronic/optical instrument used for angle measurement, distance measurements, and coordinate readings in mining.

StarStarStarStar

Underground Surveying

StarStarStarStar

Adaptation of surface surveying techniques for the mining environment where GPS is not available.

StarStarStarStar

Theodolite Surveying

StarStarStarStar

A technique where a theodolite is used to make precise measurements of angles in the horizontal and vertical planes.

StarStarStarStar

Electronic Distance Measurement (EDM)

StarStarStarStar

Technique using electronic instruments to measure distances between points.

StarStarStarStar

Volumetric Surveying

StarStarStarStar

Calculating volumes of stockpiles or excavated areas to monitor and manage mine production.

StarStarStarStar

Control Surveying

StarStarStarStar

Establishing reference points to use as a base for future surveying activities within mine sites.

StarStarStarStar

Photogrammetry

StarStarStarStar

Creating measurements and maps from photographs, used for planning and monitoring mine progress.

StarStarStarStar

Aerial Photogrammetry

StarStarStarStar

The use of drone or aircraft photography to create maps and 3D models of mine sites.

StarStarStarStar

Mine Surveying Software

StarStarStarStar

Software solutions that bring together data from various surveying instruments to create comprehensive mine maps and models.

StarStarStarStar

Perspective Grid Method

StarStarStarStar

A plot of the mine workings viewed from above, used for visually representing spatial relationships in underground mining.

StarStarStarStar

Convergence Measuring

StarStarStarStar

Technique to measure the closure or opening of underground openings to monitor stability.

StarStarStarStar

Stope Surveying

StarStarStarStar

Surveying method focused on the measurement and evaluation of ore body removal in open stopes.

StarStarStarStar

Benchmarking

StarStarStarStar

Establishing points of known elevation and position to serve as references within the mine.

StarStarStarStar

Cross-Section Surveying

StarStarStarStar

Creating cross-sectional profiles perpendicular to the mine trend to detail the underground topography and geology.

StarStarStarStar

Time Domain Reflectometry

StarStarStarStar

A technique using the time difference between emitted and reflected electromagnetic waves to measure distances.

StarStarStarStar

Seismic Surveying

StarStarStarStar

Using the reflection or refraction of seismic waves to map geological structures.

StarStarStarStar

Slope Monitoring

StarStarStarStar

Assessing slope stability using techniques like laser scanning, radar systems, and prism monitoring to prevent landslides.

StarStarStarStar

Geodetic Surveying

StarStarStarStar

Surveying that takes into account the curvature of the earth to obtain precise measurements over large areas.

StarStarStarStar

Pit Design Surveying

StarStarStarStar

Specialized surveying to create an optimal pit design by defining the most economical limits of the pit.

StarStarStarStar

Rescue and Recovery Surveying

StarStarStarStar

Surveying techniques adapted for use in emergency situations, such as post-disaster mapping and rescue planning.
