Laboratory of theory and technology for underground construction
Head: Yu.A. Epimakhov, Dr. Sci. (Eng.)
Research areas:
• Development of research backgrounds for intensifying the construction of special purpose underground
facilities in rock mass and improvement of their safety against external dynamic effects.
• Monitoring of geosystem for underground facilities.
The Institute is the leader in development and construction of special underground complexes having different
purposes and in grounding new methods for protection of structures against strong dynamic effects. The scientific
concept has been realized at designing and construction of special universal complexes, having no analogues within
the practice of underground construction in rock mass.
Express technology is based on the study of the mechanism and resulting factors of blasting in rock mass and on developed
research-methodical principles for intensification of drilling and blasting operations. The latter are based on bulk blasting
being used in connection with widely applied contour blasting and methods for instrumental control over seismic effect of blasting
and rock mechanical state of rock mass surrounding the facility.
A concept has been developed to be the first partially realized at some underground facilities for monitoring over underground
construction on a model of rock mass as discrete, hierarchy-block geophysical environment.
Principles of self-organization of structural-block structure of rock mass have been revealed at construction of underground tunnel
complexes under the influence of natural and mining-induced factors; based on them, the methods for diagnostics of the centres of
strong rockbursts and mass rock caving into the tunnels have been developed as well as for their forecasting in time by means of
high-precision deformation observations. Methods for efficient diagnostics of rockbursts hazard and stability in time of contour
of large-size underground facilities have been developed and implemented with portable geophysical and geodetic instruments.
