In-depth analysis of seismic data quality

Seismic analysis plays a big part in the day to day operations of most deep underground mines. This is mostly due to the high risk large seismic events pose to the stability of underground excavations.
Seismic analysis techniques are used to identify areas with high risk and determine the appropriate geotechnical controls to mitigate this risk. Therefore, these analysis results could be vital in reducing the impact of seismic events on operations. However, when seismic datasets have data quality concerns, those results could end up being meaningless.

IGM geotechnical specialises in seismic data quality analysis and fault finding and is widely considered industry best. We offer the following data quality services:

• Seismic density plots

• Systematic shift determination

• Under-recording of seismic source parameters for large events

• Detection of blast type events

• Detection of seismic data quality artefacts.

We strive to help you fix your data quality problems and to ensure the quality of your seismic database. This will ensure seismic analysis results that can be trusted to add value to your mining operations.
