Methodology of Geomechanical Research 1300-WMGGM-GES

The classes include the following topics:
1. Methods of determining physical rock parameters (2 h)
2. Methods of determining dynamic constants of elasticity (6 h), based on:
- measurement of the longitudinal wave propagation,
- measurement of the longitudinal and transverse wave propagation,
- measurement of the longitudinal and surface wave propagation,
3. Methods of determining susceptibility to compression (4 h), based on:
- analysis of point load index,
- analysis of regular samples,
- analysis of irregular samples,
4. Methods of determining Young’s modulus (6 h):
- based on ISRM recommendations (average, tangent, incisive),
- based on measurements of piston displacement.
- based on analysis of cyclic loading and unloading according to norm PN-EN 14580
5. Methods of determining rock susceptibility to stretching (2 h), based on:
- direct method,
- indirect method (Brazilian)
6. Methods of determining angle of internal friction and cohesion (6 h), based on:
- Coulomb-Mohr criterion,
- Fairhurst criterion,
- classical tri-axial compression tests,
- multiple destruction tests,
- continuous destruction tests
7. Methods of determining resistance to fracturing (4 h), based on:
- tests with continuous load increase (level I),
- cyclic loading and unloading tests (level II).
