Maptek brings fragmentation analysis option to PointStudio 2020

A powerful fragmentation analysis tool is a highlight of Maptek’s new PointStudio 2020 geospatial modelling and reporting software.

Better understanding of fragmentation can account for downstream cost efficiencies, with implications for many aspects of an operation, according to Group Product Manager Mine Measurement, Jason Richards.

“Sub-optimal fragmentation is immediately associated with inefficient excavation and haulage,” Richards said. “Undue damage to crusher parts is another impact. Excessive energy usage, crusher downtime due to wear and tear outside of planned maintenance and delivering out-of-specification product are directly linked to operational performance.”

PointStudio Fragmentation Analysis, released to customers this week, allows key performance indicators to be achieved consistently, Maptek says.

Individual rocks can be modelled from scanning of muck piles and draw points to provide accurate fragmentation S-curves from blasting or caving operations.

The new tool allows blast engineers and surveyors to quickly assess the condition of blasted rock, ideally before the material heads to the crushing process, while oversize rocks can be isolated for more effective haulage and processing, the company says.

“A simple scan-analyse-report workflow provides a table where rocks outside of spec can be identified and dealt with before the material gets anywhere near the plant,” Richards said. “A unique feature allows editing rocks or fines in the 3D view and characterising any that are not correctly defined.”

Visual and tabular reporting is immediately understandable so rock can be fed with optimal dimensions for crushing, according to the company.

Fragmentation analysis on 3D data is considerably more powerful and intuitive than methods that rely on analysing imagery. For operations with Maptek BlastLogic, the digital output can be used to compare actual with predictive fragmentation for continuous improvement of drill and blast processes.

While Fragmentation Analysis is a paid add-on in PointStudio 2020, many other new and enhanced features will be delivered to existing customers for free in the update, Maptek says.

One of the new options allows field surveyors using R3 laser scanners to complete scan registration immediately after scanning has finished.

“We’ve made it possible for fully registered scans to be imported from the scanner controller tablet into PointStudio,” Richards said. “Subsequent scans can then be registered with a single click as they are acquired.”

Surveyors can immediately start interrogation, analysis and modelling in PointStudio. An additional benefit derives from field access to aligned scans, allowing timely checks for survey coverage before moving to the next position.

Mine operations commit significant effort to the capture and measurement of as-built data for working faces and stockpiles, Maptek says.

“They can’t afford to let data inaccuracy and inefficient processing prevent them from getting full value from their survey data,” Richards added. “Bad data can lead to poor productivity and risks bad decisions based on incomplete information.”
