Dynamic Anisotropic Mineable Shape Optimizer (DA-MSO)

GeoMine Stopemizer is a stope and minable shape optimization tool for underground mine planning. Given a block model and a set of engineering and economic parameters, Stopemizer creates an optimal stoping boundary and then mineable shapes. For accuracy, Stopemizer uses 3D triangulation (as opposed to sub-cells)  to guide stope positioning and sizing, subject to min/max stope size and dip angle constraints. In addition, Stopemizer is capable of creating Dynamic Anisotropic Minable Shapes (DAMS) that accurately follow the orebody strike and dip, and hence minimize dilutions. 

Stopemizer is applicable to underground mines using any stoping method. If your mining method requires block caving or sub-level caving, please check out our Cavemizer module instead.

Stopemizer Key Benefits

  • Performance: Optimizations usually takes minutes to complete, affording what-if-analysis.
  • Accuracy: Using 3D triangulation (as opposed to sub-cells) to guide stope positioning and sizing
  • Adaptability: Ability to use dynamic anisotropic paths (polylines or surfaces) to create DAMS.that minimize dilutions for narrow vein deposits
  • Flexibility: In addition to internal constraints (min/max stope sizes and dip angles), accepts external constraints (such as distance to faults or existing excavations) to further confine the optimization process.

Stopemizer Feature List

Automatically determines the optimal stoping limit (3D triangulation) that maximize total profit for a given block model using custom formulae.

Optionally uses any user–defined 3D triangulation as the stoping limit (particularly beneficial for narrow vein deposits)

Automatically creates regular minable shapes or DAMS (Dynamic Anisotropic Mineable Shapes) from a stoping limit, subject to min/max stope size and min/max dip angle (internal) constraints.

Supports variable level height.

Supports optional rib and/or sill pillars.

Uses 3D triangulation as opposed to sub-cells to guide stope positioning and sizing.

Optionally uses dynamic paths (polylines or 3D open mesh) to further enhance stope positioning and sizing for narrow vein deposits. 

External positional and exclusion constraints, such as minimum distance to faults and existing excavations, can be used to further confine the optimization process.

Both hanging-wall and foot-wall trough angles can be used to reduce dilution.

Precisely computes stope reserves and generates detailed reserve report, including stope dilution.
