This division of Nagpur centre is well equipped for mines of large, medium and small sizes where innovation, engineering safety and scientific investigations are the key concerns. Solutions so provided have benefited mines of Goa, Maharashtra, Madhya Pradesh, Jharkhand, Karnataka,Kerala and Tamilnadu states of India .





Section 2: Geotechnique & Mine Modelling
Geotechnics & Mine Modelling Section
(for mines, tunnels and underground works)
The Geotechnics & Mine Modelling section at CSIR-CIMFR Unit 1, Nagpur has been rendering Research & Consultancy services to the mining & civil sectors in the fields of Slope stability, Rock & Soil mechanics, Ground Control, High wall mining, Underground Stope Design, etc. using empirical, analytical & numerical modelling techniques.
Over the last 15 years, it has completed over 150 number of industry sponsored projects in the above fields in underground mines, opencast mines & civil engineering projects. An Indo-Australian R & D project for the Design of guidelines for high wall mining in Indian coal mines is also underway. The section is equipped with well qualified & experienced scientists & technical staff. It has softwares like FLAC-3D, FLAC-Slope, GALENA, GeoSlope Studio, COMSOL, etc. for use in different scientific studies involving normal & complex geotechnical & rock mass conditions. The main areas of its activities are:
