Open-pit Monitoring

ESG provides microseismic monitoring of open-pit mining operations. These systems can be used to monitor:

  • High wall slope stability
  • Surface movement
  • Active areas of fractures and faults
  • Natural seismicity

How it Works

ESG’s microseismic monitoring systems can be custom fit into any underground or open-pit mine.

An array of triaxial seismic sensors (geophones or accelerometers or both) are installed underground and/or on the surface to detect and measure the microseismic events associated with regional (natural) or mining (induced) stresses that are occurring within the mine.

Benefits of Microseismic Mine Monitoring

Understanding rock mass behavior—Microseismic monitoring gives mining engineers’ information about the local state and stress conditions of the rock mass. By receiving real-time information on the location of seismic events, engineers and operators can learn where these events are occurring relative to mine openings and active workplaces and visualize how these conditions are changing over time. By understanding how the rock mass is behaving, operators can infer which mining activities are affecting the overall structure, and by how much.

Overview

ESG has been providing microseismic monitoring solutions to the international mining industry for over 25 years. We have developed an extensive suite of comprehensive monitoring systems that provide engineers with a continuous stream of real-time information critical to planning and hazard assessment.

ESG’s microseismic instrumentation and services helps mining and ground control engineers characterize and understand how the rock mass responds to excavation and extraction operations.
