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.”

SICK UK launches ‘first safety-certified outdoor laser scanner’

SICK UK has launched its outdoorScan3, the first laser scanner in the world to, it says, be safety-certified for use outdoors.

The outdoorScan3 Safety Laser Scanner safely and reliably monitors hazardous areas around machines and industrial vehicles outdoors with a high level of availability, according to the company. It answers the need for a high-performance safety scanner certified for outdoor use in industrial automation and intralogistics environments, as well as for integration into autonomous and semi-autonomous vehicles used in sectors such as airports, agriculture, and mining, SICK UK says.

The outdoorScan3 can be used in safety applications requiring certification to PLd (EN ISO 13849)/SIL2 (EN 62061) and is additionally a class D device, according to IEC TS 62998, the new technical specification governing outdoor use.

“Equipped with SICK’s safeHDDM™ time-of flight infra-red scanning technology, already used in SICK’s microScan3 family, the SICK outdoorScan3 uses intelligent algorithms to filter out the influences of bright sunlight, rain, snow and fog,” the company said. “With the outdoorScan3 onboard, automated guided vehicles (AGVs) can be certified for travel between indoor and outdoor industrial environments and thereby enable the continuous workflow of materials between production halls or warehouses.”

Dr Martin Kidman, SICK’s UK Product Manager for Machinery Safety, says: “The outdoorScan3 ably masters a delicate balance between performance and resilience to outdoor influences. It has the sensitivity needed to detect people or objects in its monitoring area reliably. At the same time, it is more resilient to the pitfalls of frequent error stops as a result of harsh weather, dirt or dusty environments.

“Until, now there has been no opportunity for outdoor applications to be safety-certified. IEC TS 62998 provides a new technical specification for compliant devices, and the outdoorScan3 is the first to meet the requirements for a Class D device.”

With a wide scanning angle of 275° and a protective field range of 4 m, the outdoorScan3 achieves a total safe scanning area of 38.4 m² with a minimum response time of 90 m, the company said. The outdoorScan3 can monitor up to 128 individual and freely-definable protective fields, and up to eight fields simultaneously, giving it ability to respond dynamically to the changing environment around it, SICK UK said.

The scanner offers options for integration using SICK’s Flexi Soft safety controller and SICK Flexi Soft EFI-pro gateway. Up to six outdoorScan3 devices can be networked into a safety system, with the option to integrate safety encoders for safe motion control. “Configuration and field set up is easy using SICK’s intuitive SafetyDesigner™ software tool,” the company said.

Resilient to ambient light with an intensity of up to 40,000 lux, the outdoorScan3’s intelligent software algorithms filter out the influences of snow (light to moderate) and rain to a precipitation intensity of 10 mm/h (moderate rain). Safety is ensured in foggy conditions by the fogSight function, which detects when meteorological visual range values eclipse 50 m and turns off the safe outputs. The outdoorScan3 can be used in temperatures from -25°C to +50°C.

The new safe contour detection fields provide additional versatility for mobile vehicle applications, such as safe AGV docking and protecting workers at narrow access points, SICK UK says.

“With a ‘non-safe’ warning field range of 40 m, the outdoorScan3 also can also output raw measurement data via Ethernet for navigation purposes, so safety and navigation duties can be achieved with a single device, without the need to use a separate scanner for navigation,” the company said.

SICK UK concluded: “It is likely new applications for the outdoorScan3 will be developed as users explore the potential of a new technology to operate in outdoor environments To support its customers, SICK has opened an outdoor development and testing centre at its headquarters in Waldkirch, southern Germany, to explore and develop best practice in outdoor safety sensing and systems.”
