Underground research facility St. Barbara mine

Lab Activities

Underground research facility St. Barbara mine was founded for professional and scientific research, for educational purposes and testing required for the mine development. The test sites serve for development and installation of permanent and temporary experiments, as well as the performance of research activities and tests in the area of ventilation, safety, geotechnics and field monitoring, underground repositories, underground excavations and support systems. The set experiments are also used for conducting fieldwork, demonstration and practical exercises of courses within the undergraduate and graduate study of Mining.

Analytical procedure and test method
Microclimate measurements

The current experimental setup for microclimatic parameters allows simultaneous and continuous measurement of barometric pressure, temperature and humidity at multiple points in the mine. The data is analyzed and stored on a PLC, used to control the operation of the fan and transmitted over a GSM network remotely.

THM effects The THM effects experiment enables measurements of changes in rock, filling material and heater in real conditions, and refers to damage and thermal expansion of rocks, swelling and changes in filling material, tank corrosion, experimental instruments, impact on measuring equipment and similar.

Radon level measurement

Periodic measurement of radon concentration is carried out as a control of living / working conditions in the mine, in order to assess the need to protect people from natural ionizing radiation. Measurements are carried out periodically as needed, in the atmosphere of the mine and in the bedrock (bulk material) and in the soil around the mine.
