Assessment of liability of mass rock to rock bumps
- Investigations and assessment of coal and rock liability to rockbursts
- Investigations and assessment of rock mass liability to rockbursts - index of the liability of rock mass to rock-bumps WTG and index of rock mass kinetic energy WEk
- System of the geological-geo-mechanical indicatory assessment of the liability of rock mass to rock-bumps "GEO"
- Index of natural rock-bumps hazard WNT, where geo-mechanical properties of rocks, seam depth and also seismic activity of the rock mass due to mining effects are taken into consideration
- Consultations - assessment of liability of mass rock to rock bumps.
Investigations into the features and properties of rock and strata (rock mass)
- Full-scale laboratory tests relating to strength-deformation parameters of coal and rocks (including post-critical parameters)
- Roof classification
- Investigations into the state and reach of fractures in strata (rock mass), surrounding mine workings using different methods
- In situ investigations in respect of strata strength parameters using the borehole penetrometer
- Investigations and assessment of caved debris stability
Investigations and assessment of slope stability
- Slope stability assessment in opencast mines
- Assessment of safe parameters of mined rock tips
Investigations and assessment of suitability of building materials
- Quality assessment of crushed stone, broken aggregates, concrete articles (setts, sidewalk rims, kerbs), ceramic building products, organic and mineral-organic resins
- Assessment of massive rock suitability for the needs of building engineering and highway engineering
- Non-destructive strength tests of concrete constructions (also rock massive) by means of the shock elasticity method
Support selection for safe maintaining of mine workings
- Determination of support load of mine workings depending on strata properties, rock mass pressure and environment susceptibility to tremors
- Selection of longwall support
- Selection of road standing support
- Design of individual road roof bolting support for working excavations destined for stowing etc
- Design of auxiliary standing support:
- road support strenghtening
- rock mass reinforcement
- top section anchorage (for crossings with longwalls)
- Tests and control of bolt operation
- Tests and control of roof bolting operation
- Design of specific types of roof bolting (deep roof bolting, barrier roof bolting etc.)
- Design of protection method against floor quelling
- Consultations on safe mine working maintenance in places of specific rock mass structure disturbance
