2DRing
Design Input
Within 2DRing, the creation of a design follows a
systematic engineering approach, which can be divided into
the following steps:
Definition and selection of ring planes
Definition and location of regions to be blasted (stope
outlines), drilling drives and drill positions.
Blast hole drilling.
Selection and loading of explosives.
Selection and loading of accessories (delay
detonators, primers, down-hole and surface
sequence)
Definition and Selection of Ring Planes
Before the definition of blasting regions (ie. stope outlines),
drilling drives, drill positions and drill holes, the user must
create and select the "ring plane" where all these objects
will reside. In 2Dring, a ring plane can be defined as the
top of the hierarchy of design objects.
To create ring planes the user must go to the
Parameters+Select Ring planes menu item or
alternatively by pressing on the ring planes/drives/drill
positions design mode icon and then in the parameters icon
(see left).
The "select ring plane for design" dialog is then activated
(see Figure 2.1). This dialog box displays the list of ring
planes in the current design, the user may select any of
these to create drill drives and position blast holes. As
shown in Figure 2.1, two default ring planes are available.
