Auto Excavation and Dump Sequencing

Optimize dumps

• A dump hierarchy

  • Excavation is automatically executed according to a schedule generated within 3d-Dig. Material reports automatically to a dump hierarchy. This module is invaluable for visualizing various development scenarios, testing order of development and visualizing interaction of excavations and dump volumes.
  • Development sub-sequences can be excavated in any order. A hierarchy of dumps can be assigned to each sub-sequence and a pre-set productivity can be assigned to each subsequence/dump combination. This pre-set productivity controls the progress of the simulation of the super-sequence.
  • Development sub-sequences (each a contiguous series of mining blocks) can be excavated in any order. Just by changing a few parameters, complex multi-stage dumps are rapidly re-build and re-simulated.
  • In most mining simulation models dumping with predefined dump geometry subdivided into blocks. 3d-Dig however simulates dumping from first principles. Dumps can be constrained by geometric models but the dumping process is simulated by modelling material flow.
    
    Once the simulation is set up the dump model can be rapidly changed and the simulation rerun. 3D-Dig can simulate the incremental dumping of equipment such as draglines and bulldozers. Hence dumps can be automatically generated which are a function of the equipment and operating method.

• A super-sequence

  • Sub-sequences are assembled into a tree, called a super-sequence. A hierarchy of 3D-Dig dumps can be assigned to each sub-sequence and a pre-set productivity can be assigned to each subsequence/dump combination. This pre-set productivity controls the progress of the simulation of the super-sequence. Dumps are constructed via simulation using the 3D-Dig Dump Algorithm.
  • This method does not require a block reserves model of the dump. Consequently, once a simulation is set up, substantial modifications to the dumps can rapidly be implemented and the simulation re-run. As a dump in a hierarchy fills, dumping automatically switches to the next dump in the hierarchy.
    
    This module is an invaluable tool for visualizing various development scenarios and transport distances, for testing order of development and visualizing interaction of excavations and dumping volumes.
