Numerical Modelling Activities

Numerical modelling is one of the major and widely accepted tools for design of excavations in rock. The Numerical Modelling Department consists of experienced team of geologist, civil and mining engineers, having expertise in providing solutions to varied problems related to excavations in rock. Anticipated rock mass behaviour around an excavation can be reliably predicted using the latest Finite Element Method (FEM), Finite Difference Method (FDM) and Discrete Element Method (DEM). 

Various software based on these numerical methods are available in the Institute. The Numerical Modelling Department possesses vast experience in carrying out slope stability studies, stress analysis and support design for tunnels, underground caverns and large excavations applicable to both civil and mining engineering. Along with the numerical modelling, the department also provides services related to instrumentation and monitoring of all types of underground excavations.

numerical Modelling

Our projects related to design based on numerical modelling for underground caverns are:

  • Stress analysis and design of caverns using continuum (FLAC3D) and discontinuum (3DEC) numerical modelling software.
  • Design of different types of supports in excavation such as steel ribs, rock bolts and SFRS (steel fibre reinforced shotcrete).
  • Coupled thermo-hydro-mechanical analysis of the rock mass.
  • Ground water flow analysis.
  • Dynamic analysis for analysing earthquakes, seismicity, and mine rock bursts.
  • Thermal analysis for analysing both conduction and advection in materials for nuclear waste disposal.
  • Analysis of creep i.e. time-dependent material behaviour of rock using latest numerical modelling software.
