Tests of physical and mechanical properties of rock and concrete

testing physical (density, absorbability, porosity, soakability), mechanical, strength and deformation (compression, shear, bending) properties of rocks in complex stress conditions (uniaxial and triaxial)
testing strength parameters of concrete, plastics, minerals, steel and cast iron
establishing the criterion of rock destruction and evaluation of their bump inclination
determining the rheological properties of rocks and creating rheological models for different rock types
establishing the entire mechanical characteristics of rocks including before and after destruction states
model tests of rock pillars behavior in static and dynamic load conditions.

Monitoring and testing the state of mine support and lining

monitoring of rock bolts and hanging wall behavior using extensometers and instrumented bolts in order to verify the rock bolting selection
evaluation of strength parameters of concrete and brick lining using the complex, sclerometric and ultrasound testing
measurements of thickness of cast iron elements of tubing lining and flaw detection tests of anchors fitting the shaft equipment to the shaft lining
measurements, calculations and mapping the land deformation:
- monitoring lines (angular-line measurements, leveling)
- grids on shaft sites in LGOM mines (GPS and angular-line measurements; leveling)
- horizontal basic and detailed raster for LGOM mines (GPS measurements)
comparation of electro-optic range finders
survey measurements with results evaluation
measurements of measuring points dislocation using the GPS technology.

Tests of pipes and backfill quality

tests of physical properties of hydraulic backfill (grain size distribution, water permeability, compressibility, density) and solidified backfill (grain size distribution, density, stiffen time, soakability, uniaxial stress strength, compressibility, water permeability etc)
test of backfilling installations
wear tests of backfilling pipelines (measurements of pipe walls thickness)
testing the parameters of backfill slime flow (pressure measurements)
investigations on improving the backfill pipes management (new pipe types).
