Microgravimetric surveys in the mine area

In October 2024, our company conducted microgravimetric surveys in the northeastern part of the Upper Silesian Coal Basin (within the Trzebinia municipality).
The objective of the order was:
– study of the near-surface structure of the ground (recognition of the state of the rock mass) in connection with the shallow exploitation of deposits (up to 100 m below the surface),
– to identify potential sites threatened by the possibility of new discontinuous deformations in the studied area.

Scope of work:

  • The survey covered an area of more than 6 hectares, where 800 measurement points were distributed. The CG-5 Autograv gravimeters of the Canadian company SCINTREX were used for the measurements.
  • Necessary surveying measurements were also made using Leica equipment.
  • The work was carried out following the guidelines from the Ordering Party, including the analysis of geological and mining conditions, land use, and utility networks.
  • To minimize the influence of external factors on the accuracy of the data, part of the surveys were carried out at night.

The surveys were essential because sinkholes had arisen in the area due to mining activities. We obtained detailed information on the condition of the ground. Abnormal areas that could indicate the presence of post-mining voids or loosening were identified.

In November, our engineers were busy interpreting the results and preparing full documentation, including maps of residual anomalies, descriptions, and conclusions of the gravimetric surveys. This will help SRK S.A. with further activities related to zone safety and the planned drilling works.

We are pleased that our extensive experience in geophysical surveys could be used in planning further activities to support the safety of people and their possessions in this region of Małopolska.
