Underground research facility St. Barbara mine
Lab Activities
Underground research facility St. Barbara mine was founded for professional and scientific research, 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 ventilation, safety, geotechnics and field monitoring, radioactive waste and spent nuclear fuel management, 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 engineering.

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 analysed and stored on a PLC, used to control the operation of the fan and transmitted over a GSM network remotely.

| Mjerenja u svrhu modeliranja procesa ventilacije podzemnih prostorija, strujanja i kvalitete zraka |
Unaprijeđenije podzemnog istraživačkog poligona, proširivanjem broja mjernih parametara i gustoće mjernih točaka, kako bi se ostvarila baza za modeliranje procesa ventilacije podzemnih prostorija, strujanja zraka te kvalitete zraka. |

THMC effects
|
The THMC effects experiment enables measurements of changes in rock, buffer material and heater in real in situ conditions, and refers to damage and thermal expansion of rocks, swelling and changes in buffer material, cannister corrosion, effects on instruments and measuring equipment.

Full-range tensiometer measurement
|
Functional measurement system for measuring water pressure/tension, soil temperature and soil moisture. |
|
Radon concentration measurements
|
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. |
