Background

 

The 3d-DigPlus Automated Excavation and Dump Sequencing system allows complex schedules to be automatically excavated and optionally dumped. Large excavations are automatically subdivided into small increments and these increments can be arranged into a Supersequence (schedule).

Supersequences can be run to simulate the excavation operation, and dumps can be assigned. As each increment is excavated its volume reports to the appropriate dump. The system allows for a hierarchy of dumps so material reports to the first dump until this is full and then reports to the second etc.

Once the Supersequence is set up with allocated dumps the process can be simulated. Dump constraints can be subsequently changed and simulation rerun producing a different dumping scenario. In this manner the user can rapidly investigate a variety of dumping options.

Common dumping problems such as premature filling of allocated dumps and unplanned long and high hauls can be rapidly identified and  more optimal solutions found.

The system allows for:

•The design of complex staged excavations. Material can be excavated on a block by block basis using Pit, Strip, Pass and Lift.

•The design of Staged Dumps. Dumps can be limited in planar extents, by multiple design surfaces or by level. They can be built progressively in lifts and in a nominated direction.

•Construction of stratified dump. Where dumps are constructed of different material types, each material type can form an independent layout within the dump. This results in a stratified model of final dump and allows particular material types to be constrained to particular dump locations.

•The linking of excavations and dumps. Portions of a staged excavation can be linked to specific dumps. A hierarchy of dumps can be established such that the dumps will be filled in sequence.

•The sequencing of staged excavations to conform to a schedule. This includes multiple pits, advanced stripping and multiple parallel operations.
