Underground scanning is important to understand the behaviour of walls, to check if there is movement or not. Furthermore, this type of workflow makes the processing of raw data much easier with the semi-automated point cloud registration, upon importing the data into the Magnet Collage software, a much needed functionality for working on large scale projects, where accuracy is a standard requirement. The Topcon GLS 2000 3D laser scanner supports various surveying methods such as the “occupy and backsight” (a traverse-like functionality that makes it possible to set up the instrument on a known point i.e., control point), sight to a prism set up on another known point for geo-referencing purposes and lastly, to get the most accurate scan data. Though the Topcon GLS 2000 laser scanner is not intrinsic safe, it can be deployed in other underground mining operations that do not require an intrinsic safe surveying instrument for underground mass data collection. But how about we explore a little of 3D laser scanning in the underground mining operations? 3D laser scanners have flooded the surveying market, especially for mass data capturing and ensuring collection of critical surface details being scanned. One of the best ways to be productive on site and render accurate data is through 3D laser scanning. Traditional survey techniques have proven to be very accurate over time, however, collecting data using such methods can be time consuming on large scale projects, where production and accuracy cannot be compromised. Technology has been changing over the years and has drastically changed how surveyors collect data for mapping purposes.
