Automated Dragline Simulation

Automate your dragline simulation

This module simulates complex multi-pass Dragline Development. This is done by breaking the development into sub-passes, with a number of Dragline Moves carried out in sequence in each sub-pass. This simulation builds on the Single-Step Dragline Module and the Automated Excavation and Dump Sequencing Module. Dragline Bench, Arc Area and Boom Dumps and Dozer Bench Dumps can be assigned to each Move. Once a Dragline Simulation is set up, users can easily change parameters to find an optimal development strategy.

Optimal development strategy

Design multi-pass dragline strip
- The Automated Dragline Simulation system automates the design of a complete, multi-pass dragline strip.
- While the system does not simulate the full detail of each block as performed by the dragline operator, block sized segments of the pit are simulated in sufficient detail to calculate prime and rehandle volumes and to assess spoil fit.
- Steady state sections of a strip are modelled with accuracy similar to a manual 3D-Dig modelling exercise.
- Ramps and endwalls are modelled in an approximate manner. However the system has the ability to pause when approaching these situations. This allows the user to continue manually if necessary, then re start the automated process.
Subpasses and supersequences
- Setting up a strip for automated dragline digging is initially very similar to setting up for Automated Excavation & Dump simulation.
- Subsequences are replaced by Subpasses and combined into a Supersequence. Each block in a Subpass is used to form a Modelling Block.
Dragline steps, moves and procedures
- Each modelling block will consist of several (as many as the method requires) Steps. A Step is the basic increment of the full set of moves required to excavate a complete modelling block for a given pass or sub-pass. Each step consists of an excavation and a dump. The number of Steps and the geometry of the associated excavations and dumps vary with the operating method.
- Excavation Steps extend, parallel to the pit, for the full block length. Dump Steps will extend as required in a manner that ensures dumping takes place within the draglines reach. A complete set of Steps sufficient to complete a full modelling block of a given pass is referred to as a Procedure. Procedures are applied to Subpasses.
Easily change parameters
- Once a Dragline Simulation is set up, users can easily change any parameters to find an optimal development strategy.
