Stochastic Cave Optimization, Design, Simulation & Scheduling

Automatically determines the best footprints for a single deposit.

Creates and iterates your designs; Automatically generates cross-cuts from a cave design.

Defines your own caving stages, each with its own recovery and external dilutions; Reports precise mineable reserves for each caving stage.

Simulates the material flow of block caving operations and generate optimized production schedules. This sub-module combines a physical mixing model (to simulate material movement and dilution) with an economic scheduler that maximizes Net Present Value (NPV).

This tool allows you to:

• Simulate granular material flow (mixing) inside the cave.

• Schedule production based on mill capacity and grade constraints.

• Manage stockpiles for low-grade material.

• Visualize cash flow, tonnage, and grade over the life of the mine

The stochastic caving workflow is a three-phase consensus design process, encapsulated in a multi-tab GUI: 

• Phase 1 –  Per-realization footprint voting: run the cave footprint optimizer runs once per block model realization (each BM is a geostatistical simulation). 
• Phase 2 – Consensus design: create a Consensus design from all footprints.
• Phase 3 – Stochastic scheduling: run the caving scheduler N times against the consensus design – once per realization BM – to propagate geological uncertainty into outcome distributions (P10/P50/P90 NPV, production profile, mill feed/grade, cumulative discounted cash flow). 
• Phase 4: Sensitivity Analysis: repeat all 3 phases for each parameter sweep
