Real-Time Mining project

The overall aim of Real-Time-Mining is to develop a real-time framework to decrease environmental impact and increase resource efficiency in the raw material extraction industry.

The key concept of the research conducted is to promote a paradigm shift from discontinuous to a continuous process monitoring and quality management system in highly selective mining operations.

The impact of the project will be achieved through improvements in process efficiency and resource utilization. These will increase energy efficiency and facilitate significant improvements in the environmental performance of mining operations by reducing the emissions and wastes generated. It is considered that deposits which are currently thought as economically marginal or difficult to access could become viable.

Eijkelkamp SonicSampDrill is investigating if we can determine the compressive- and tensile strength of rock from the Monitoring While Drilling data. Tests done in cooperation with the Institute for Advanced Mining Technologies of the RWTH Aachen University proved that we can pick up information with an “Acoustic Emission Sensor” from high frequency vibrations. The theory is that by picking up on these high frequency vibrations we can measure the origination of small fractures inside the rock.

Real Time Mining

Above our test. We mounted an Acoustic Emission Sensor on one of our CRS-T masts and drilled trough granite, concrete and clay. In the graph on the right you can clearly see the different patterns. Our aim is to be able to pick up on the transitions from different layers or fractures.
