Our Mandate

To undertake R&D work on slope stability of opencast mine slopesand hill slopes to ensure safety of men and machineries.


About us

This Research group has expertise and experience of more than 30 years in the area of slope design and slope monitoring. This group is equipped with modern and sophisticated R&D equipments such as 3D Terrestrial Laser Scanner, Electronic Total Station and other laboratory equipments. 

Our Expertise
  1. Slope stability design of open pits and OBdumps -external and internal.
  2. Slope stabilisation measures.
  3. Slope safety monitoring and prediction of slope failures for protection of men and machineries.
  4. Geotechnical studies and landslide hazard detection.
  5. 3D Laser Scanning of mines for 3D modelling and excavation volume computation and slope movement monitoring.

Our Accomplishments
  1. Designed the slope of deepest openpit mine (Rampura Agucha Mine), HZL with depth of approximate 420m.
  2. Designed the steepest slope of Chandmari Copper Project, Khetri, Rajasthan with overall slope of pit as 60 degree for a depth of approx 150m.
  3. 3D Terrestrial Laser Scanning and 3D modelling of CCL, MCL and other mines.
  4. Precise surveying and periodical excavation volume computation work in a large number of opencast mines of WCL and MCL.
  5. Overburden dump design for disposal of flyash in OB dumps.

Sl. No.A brief description of Facilities/ Equipment/Tools/software with photos
Major Facilities

Schmidt Test Hammer: Used for determination of rebound values of hard rock surface to assess strength. 


Proctor Compaction Test: Used for compaction test of soils. 


Standard Penetration Test Apparatus (SPT): Used to characterise the ground surface for bearing capacity of ground, which in turn is used for foundation design of civil structures. 


Permeability Test Apparatus: Used for determination of soil permeability values for hydrological analysis.  


Grain Size Analysis Sieve: Used for particle size distribution analysis for soil and soft rock.


Liquid Limit Apparatus: Used for determination of soil property relevant for soil mechanics.


Point Load Tester for Rocks: Used for determination of point load index of hard rocks for slope stability design. 


Direct Shear Test Apparatus: Used for determination of cohesion and angle of internal friction of soil or soft rock. 


Terrestrial Laser Scanner (Polaris TLS):Used for 3D Laser Scanning, mine surface modelling and precise excavation volume computation. It is also used for large area monitoring of opencast slope for safety.


Electronic Total Station: Used for ensuring slope safety through periodical slope monitoring by surveying.
