Course Contents
The methods and principles of land reclamation design and
post-mining site development are presented. On the basis of an obtained digital terrain
model and a geological model together with additional information a student has to
prepare a study of a post-mining land reclamation and development with regard to
assumed social and environmental constraints. The detailed design is supported by the
specialized, three-dimensional geological modeling and mining design package
(DATAMINE) which provides the suitable software environment. The final project is
presented both in the form of 3-D models and maps with the use of mapping software
(MICROSTATION).

deformation detection software. Integration of multi-sensor observations (GPS, total
station) for high accuracy measurements, stability check of control points,
identification and separation of various causes of deformation. Laboratory exercise:
A total station is used to measure the relative position of points with respect to the
position of the robotic total station (RTS) with automated target recognition (ATR).
Small targets are placed in the areas of interest throughout the object being monitored;
the RTS is programmed to point to these targets and make precise measurements. The
measurements are performed in the predefined pattern and schedule. The raw data are
collected by RTS and then processed by the software to determine the final
coordinates, displacements, displacements velocities of all the target points.
Verification of the results. Optional: Multi-sensor observations (GPS, total station) for
high accuracy and stability check.
Mining example: excavated areas in open pit mines require stability monitoring to
guide production and safety (steeper walls mean more efficient use of resources, but
may be more prone to failure) application accurate displacement monitoring system.

combination of monitoring and numerical modelling of deformations, what is
essential for studying the processes occurring in engineering structures and in rock
