Real Time Mining

Real-time optimization of extraction and the logistic process in highly complex geological and selective mining settings

Motivation and Background

Based on the characteristics of existing deposits in the EU, research within the project “Real-time optimization of extraction and the logistic process in highly complex geological and selective mining settings” is focusing on highly complex deposits where selective mining is required.

Profitable exploitation of these deposits is highly challenging. The main potentials for a successful economic exploitation are:

  • Maximizing resource potential along the production chain by effective grade control
  • Saving energy costs and financial resources by minimizing handling of gangue material resulting from dilution
  • Optimizing resource utilization by management control of geological uncertainty resulting of limited information available

Goal

Traditional resource management is characterized by a discontinuous intermitted process including the following steps:

According data scarcity, the resource model is associated with a significant level of uncertainty. Nevertheless, mine planning decisions are taken and executed based on the initial model. Usually model based predictions and actual performances are only compared at the end of the production chain, where the opportunity for corrective actions is no longer available. The key concept of the Real-Time Mining project is to change this discontinuous process to a continuous closed-loop.

Tasks

The total project is divided into nine work packages (WP):

  • WP1: Management, Dissemination and Exploitation
  • WP2: Sustainable and Industrial Viability Indicators
  • WP3: Underground Positioning System
  • WP4: Sensors for Material Characterization
  • WP5: Sensors for Machine Performance Measurements
  • WP6: Data Integration, Measurements and Visualization
  • WP7: Rapid and Sequential Resource Model Update
  • WP8: Integrated Long- and Short Term Optimization
  • WP9: Integration and Demonstration

The Institute of Mineral Resources Engineering is involved in several WPs of the project and leads WP 8. Therefore, rapid and real-time optimization methods in the context of long- term mine development, short-term sequencing, production control and auxiliary processes will be developed, tested and implemented.

The mining process and the value chain of selected mines will be analyzed in detail and simulated using appropriate software. At defined process steps, e.g. fleet scheduling, optimization algorithms will be developed and implemented to the simulation. Using Simulation based Optimization, it is planned to integrate the real time updated resource model as well as equipment position data and material characteristics to update and optimize mining schedules in real time.
