Mine Surveying in Underground Civil Engineering

This course covers the role of mine surveying in ensuring the safe operation of underground structures, survey data, and their processing for the purposes of mapping documentation in mining operations. The course covers underground construction technologies, including conventional NRTM and Drill and Blast methods, as well as continuous TBM excavation, in direct relation to the work of a mining surveyor. It includes surveying tasks such as checking 3D design documentation, establishing surface and underground control networks, surveying using gyrotheodolites, setting out during excavation, measuring convergence, inspecting support structures using laser scanning, monitoring surface stability and overburden deformations, and relevant mining legislation.

Learning Outcomes:
- Professional Knowledge: Students will acquire comprehensive knowledge of conventional and mechanized tunneling technologies in the context of a mine surveyor’s work. They will understand the theory of stress distribution, the formation of rock arches, methods of geotechnical monitoring, and forecasting the effects of underground mining on the surface and overburden. They will master the principles of establishing survey networks and geodetic methods underground and be familiar with the relevant legislative regulations.
- Professional Skills (Abilities): The student is able to independently stake out underground structures, navigate drilling rigs, and calculate the error from a breakthrough. They are capable of performing convergence measurements, conducting comprehensive inspections of linings using laser scanning with evaluation of deviations from a 3D model, and designing, stabilizing, and evaluating observation stations for measuring subsidence and horizontal surface displacements above underground structures.
- General Competency: The student independently and responsibly decides on the selection of appropriate geodetic and mining surveying procedures during the construction of underground structures, taking into account the required accuracy, safety, excavation technology, and conditions of the specific project. They critically evaluate the quality and reliability of measurement and monitoring results, professionally assess risks associated with geometric deviations and deformations, and take responsibility for the quality of the technical outputs entrusted to them. They are able to coordinate specific surveying activities with the work of designers, geotechnical engineers, and tunneling personnel, and take technical, safety, and regulatory considerations into account when making decisions.
