Laboratory of Engineering Geophysics

Laboratory of Engineering Geophysics

Laboratory of Engineering Geophysics, where research is carried out in the field of recognizing the structure and properties of various geological structures and their behavior in various conditions. The laboratory specializes in improving the measurement and interpretation methodology of test results, using the latest hardware solutions in the field of engineering and mining seismic, seismological, seismometric, and electromagnetic (GPR) methods. The results of the research are used in practice, in the analysis of landslide and sinking processes, the stability of flood embankments, assessment of the quality of the substrate for surface and underground construction facilities, as well as for the needs of effective and safe mining and tunneling works.

Scope of research and analysis

For over 30 years, the Laboratory of Engineering Geophysics has been carrying out research in the field of:

  • GPR reconnaissance,
  • engineering and mining seismic,
  • mining seismology,
  • seismometry,
  • other geophysical methods,
  • geological-engineering and geotechnical methods, including calculations of the stability of slopes and slopes in various soil and water conditions.

The research carried out in this laboratory covers the broadly understood recognition of the structure and properties of various geological structures and their behaviour in various environmental conditions.

Laboratory equipment

The above-mentioned tests and analyses can be carried out thanks to the modern equipment of the Engineering Geophysics Laboratory. The most important elements of this apparatus are listed below, broken down into:

  • seismic apparatus: several Geode and StrataVisor units with 4.5 Hz, 10 Hz, 14, Hz, 40 Hz, 100 Hz geophones, including 4.5 Hz three-component geophones, hydrophones and auxiliary equipment.
  • seismometric equipment: high-sensitivity three-component geophones, three-component accelerometers, cooperating with the Bruel-Kjear and Geode-24 central unit,
  • GPR equipment: ProEx system with antennas: 50 Hz, 100 Hz, 250 Hz and 500 Hz and a 100 MHz hole antenna with the possibility of measurement up to a depth of approx. 120 m.

Results and directions of the use of research works

In the field of engineering and mining seismic methods, seismological, seismometric, and electromagnetic (GPR) seismic methods, the obtained test results have practical application, enabling in particular:

  • identification of the structure and properties of soil and rock mass,
  • identification of landslides and rocks prone to landslides,
  • identification of subsidence hazards in mining and post-mining areas,
  • location of voids formations and relaxation zones in the direct construction substrate, assessment of the quality of the base course for roads and railways, including defects in construction layers, consolidation of various types of embankments, etc.,
  • identification of the quality of the substrate for surface and underground construction facilities (tunnels, tourist facilities, mine workings),
  • location of technical infrastructure elements – electrical and water installations, etc.,
  • monitoring the behaviour of soil and rock structures,
  • assessment of the size of dynamic impacts on building infrastructures – the impact of seismic vibrations on objects of various types,
  • assessment of the influence of edges, remains of extraction seams and faults,
  • identification of various geological and mining conditions, including natural hazards by means of classic seismic and tomographic screening of rock mass parts, also with the use of explosives.

As part of the research, mathematical models of the behaviour of various geological structures in specific environmental conditions are also created. In the processing and interpretation of measurement data, licensed specialist software from the world’s leading manufacturers is used.
