MSO Stope Splitting

This function subdivides stope-shapes according to user defined rules. It is generally applicable for stope-shapes that are wider than their maximum stable wall span(s) or for sub-setting very-wide ore bodies. It may also have some conceptual design application for drift and fill and mechanised cut and fill type mining methods by setting split widths to development width and using a minimum and maximum tolerance on the split width. It may also be applicable for establishing shapes that correspond with blast ring increments such as for the transverse SLC mining method.

Splits can be made in either the transverse or longitudinal directions. Note that longitudinal splitting is equivalent to applying U-axis (and/or V-axis) sub-stopes from a “full” stope.

Transverse split options:

Split on a regular stope-framework grid (with optional annealing) to create a checkerboard pattern (for abutting open stoping layouts).
Offset the split wall positions between adjoining stopes (i.e. adjacent in the Uaxis sense) by using an offset from the stope-framework grid for a staggered checkerboard pattern. Only valid for grid splitting.
Split from centre.
Split equally.
Split from the near wall
Split from far wall
Split from hangingwall
Split from footwall
Split fixed width

Examples of these split options follow

See the splitting options available on the Options panel...

Example: Split on grid - Interval -10m (range 8-15m) using an offset of 5m

Example: Split from centre with internal vertical walls. Interval -10m (range 815m)

Example: Split equally with internal vertical walls. Interval -10m (range 8-15m)

Example: Split from near wall with internal vertical walls. Interval -10m (range 8-15m)

Example: Split from far wall with internal vertical walls. Interval -10m (range 815m)

Example: Split fixed width (5m splits)

Example: Split Equal applied to rotated framework with
irregular section spacing allowing sub-economic stope shapes:
