Wonawinta Tailings Dam
This project involved the construction of a tailings dam for a silver mine
project in central NSW.
The team needed to provide quantities of clay sufficient for building the wall
and the 600mm thick liner on the base. They were also required to provide
storage capacity at 0.25m increments in RL, and to produce contour plans for
scheduling the construction and issuing instructions to the contractor.
A separate model was required for each contour slice at 0.25m intervals in order
for the engineers could produce plans to aid the construction timeline.
Task 1 - Wall volumes were created using (Volumes >Tin to tin
by height range) and selecting polygon
Task 2 - Base volumes
were created using (Volumes >Tin to tin by height range) and selecting polygon
Task 3 - Storage Calculations were created using Volumes >
Exact > Storage calculations
The contours were created at 0.25m increments.
Contours had to be renamed
as their RL using
(User>Miscellaneous>R to Z>Set contour names from contour
With (Utilities>A to G>Change), and using a filter to select only
certain string names, the contours were split into their own model.
lines for each 0.25m RL were printed on a pdf with tailing dam chainages and a
grid so operators could locate themselves.
Infinity Surveys’ use of 12d Model on this project allowed them to fulfil, and
indeed even exceed, client expectations.
