Accurate stockpile modeling

Stacking

SMS3D.net can help you understand what material has been stacked where. This is achieved through the use of complex algorithmic equations that calculate the tumbling paths of materials based upon real time stockpile and stacking equipment parameters - including the movement of material by dozers.

Reclamation

A variety of different physical stockpile storage and reclamation methods can be modeled including silos, storage bins, bucket wheel, underground valve, and bridge reclaimers. The reclamation geometries, tonnages and bulk material flow properties are variables that are considered in modeling the reclamation of the bulk commodities.

Zoning Methods

3D zones can be created to simplify reporting and blend calculation and also enable the classification of “live” and “dead” zones on a stockpile pad reflecting the areas which a reclaimer can physically reach. Dead zones often require dozing to enable effective reclamation.

Recalculation Service

A stockpile recalculation service enables automatic and transparent model recalculation and regenerates the model as required.



3D Stockpile Visualisations


A variety of stockpile visualisations enable detailed analysis of the internal structure and composition of stockpiles and stockyards. Surface topographies and internal block structures are visualised in contours, cross-section, long-section, quality/grade and comparison charts.

The stockpile visualisations are rotatable and cut throughs in multiple planes enable viewing of internal stockpile structures. Views of underneath and flyovers of stockpiles enable appreciation of their relative positioning to yard equipment, meterages, northings, rail positions, reclaim valves and other key sign postings. Both two and three dimensional visualisations of the stockpiles are available.



System Integration


SMS3D.net integrates to existing plant and mobile machinery providing real time data retrieval without the need for expensive hardware components. Often through stacker/reclaimer, process plant or loadout SCADA or historian systems, QMASTOR automates the collection of weightometers, on-line analysers/laboratory analyses and material handling equipment positions and operating parameters. This automation is essential to capture the vast amounts of data required to accurately model the many stockpiles that can be located within a large bulk commodity stockyard.



Reclamation Planning


The ultimate objective of SMS3D.net is to provide users with no surprises when it comes to what is actually reclaimed versus the forecast or prediction of what will be reclaimed. The confidence of knowing that the predicted reclaimed quality will be achieved, whether from an entire stockpile or selective zones within a stockpile pad, means that users do not suffer pains from:

  • Inaccurate blend planning to meet customer requirements
  • Last minute re-jigging of reclamation and loading instructions to stockyard operators
  • Reconfiguring processing plants or suffering yield losses due to plant feed variability
  • Re-handling and re-sampling product due to uncertainty of material/product grade
  • Having to reschedule storage, segregation of product or logistics plans
  • Last minute borrows or purchases to meet contract specifications
SMS3D.net can improve the confidence and certainty within your operations.



Survey Reconciliation

The initial importing of stockpile pad base profiles and the subsequent routine aerial or land based survey DXF files contribute to a reconciliation process for the stockpile modeling. This provides a control loop for ensuring the stockpile modeling and inventory accounting system reflects what is actually on the ground and provides a framework for ongoing improvement in stockpile modeling assumptions, modeled variables and subsequent model accuracy.



Comprehensive Reporting

Reporting enables detailed analysis of stockpiles to understand distributions of materials, products, equipment used, forecast/actual datasets and of course quality and grade. If integrated with one of QMASTOR’s supply chain management systems, then relationships/links can also be made to understand the product genealogy by tracking information about transportation, shipping, process plant batches, pit contributions etc on and through the stockpiles.



Pit to Port Integration

SMS3D.net is available as a standalone product or can be seamlessly integrated with QMASTOR’s supply chain systems (Pit to Port.net, Pit to Plant.net, Port to Plant.net) for a complete end to end bulk material modelling and supply chain management solution.

A more comprehensive integrated materials management system is realised beyond stockpile management. For example, functionality can be extended to include:

Supply Chain Planning

Port or Stockyard Operations

Transport Operations

Mine Operations

Commodity Trading and Logistics

Commercial and Contract Management

SMS3D.net provides greater accuracy in the tracking of bulk material parameters due to the customised three-dimensional models employed and a significantly increased granularity when compared to the various 2 dimensional and algorithmic models employed within QMASTOR’s other supply chain systems.
