ORB - Significant increase in NPV for Underground Metal Mining Operations

ORB - Significant increase in NPV for Underground Metal Mining Operations

Polymathian's ORB produced strategic mine plans resulting in a 30% increase in NPV compared to “leading” mining software tools

The Problem

The customer operates one of the world’s largest underground metals stoping mines. Producing detailed and practical long-term mine plans for large stoping operations is an extraordinarily complex planning task.

There are over 80,000 individual tasks that need to be scheduled: 50,000 stoping related tasks and 30,000 development related tasks spanning a mine life exceeding 40 years, and hundreds of constraints that plans needs to conform to, including:

  • ventilation restrictions
  • waste, rock and paste fill production and fill capacity
  • production and development drilling capacity
  • production machinery constraints
  • other production constraints
  • mill tonnage and grade constraints
  • resource category constraints
  • task dependency and lag timing constraints
