CSIR – CIMFR, Unit-1, Nagpur, established in June-1986 is a blue chip division of laboratory and is engaged in R&D activities and technical services for the Indian mining industry.  The Nagpur centre, with its precisely articulated mandate is able to cater the technical need of mines all over the country because of its location advantage and its symbol of credibility. It has two functional sections /group as -  1. Rock Excavation & Fragmentation,  2. Geotechnique & Mine Modelling, which offers services in selected areas for mines, tunnels and underground excavations. A brief about areas of services offered by the department are as follows.

Services Offered:

1. Controlled blasting, blast design, fly rocks and ground vibration studies,  technical problems of blasting near habitats  for both in mines and tunnels for performance enhancement and productivity improvement.
2. Geo-hydrological studies , qualitative and quantitative estimation of mine water, different aspects related to mine water) 
3. Cost effective engineering solutions for slope related problems of mines as well as for other infrastructure projects (slope stability studies)
4. All problems related  to rock excavation engineering i.e. Hard rock mining (stope design, stope sequencing, design of portal, decline, shaft pillar, etc., design of surface crown, cross-cuts and other such development drives); Estimation of RMR, Support design, molti seam-working design, pillar design, stability analysis, feasibility studies for coal mines; Subsidence prediction 3D modeling (as per MOEF govt. of India norms); Highwall mine design (web pillar design, molti-seam interaction analysis, highwall slope stability incorporating web cuts, etc (Rock Mechanics and Geotechnical Solutions)
5. 3D / 2D Numerical modeling for both underground and surface mines, tunnels, caverns and any other structure in rock /soil below the ground surface.
6. Trouble shooting in underground construction e.g. Underground Space Technology and its uses for civil sector and infrastructure projects.

This regional centre is equipped with field instruments and  modern analysis tools, software namely  FRAGALYST 4.0, WIPFRAG, FLAC3D, EXAMINE 3D, GEOSLOPE, GALENA,  COMSOL, PFC 2D , MODFLOW ,DIPS ,UNWEDGE etc. to deal in some niche areas of mining and tunneling exclusively viz. Rock Blasting, Mine Water Environment, Slope Stability , Rock Engineering / Rock Mechanics and Underground Space with particular reference to underground constructions works. The department is able to offer consultancy services for day to day technical problems of mining organizations and other industrial companies e.g.  hydro-electric projects, railways, highways, irrigation etc. involving excavation and tunneling operations. Indigenous solutions and technical expertise for all type of underground works and different scale of mining operations are available.  Its workforce has international exposure too for providing deliverables and for trouble shooting to various agencies in India and also for international agencies.

In Central India, since Nagpur is the hub of mining activity and has strong industrial base an opportunity to undertake collaborative, sponsored and consultancy projects with leading industry partners, national R&D institutions / R&D groups and academic institutes do exist (List of ongoing projects). The centre is capable to provide “total engineering solution” in the above mentioned chosen areas for mining and tunneling companies as well as infrastructure / construction organizations.  The ‘future perspective’ of centre, is in tune with the laboratory mandate.

1. Excavation related issues and problems for all types of mines which include blast design, control of flyrock, ground vibration problems, air over pressure including blasting near habitats to improve productivity. ‘Innovative Controlled Blasting for Cautious Excavations' (in tunnels and mines) is an important expertise area being refined progressively. 
2. ‘Controlled blasting’ for civil excavations i.e. In tunnels, caverns, road and rail passes, irrigational channels, infrastructure projects and all types of underground construction works.
3. Rock excavation for metro construction works are also dealt by the team of scientists. The centre has an experience of Bangalore Metro too.
   
    
4. FRAGALYST Software (Version 4.0): A new user friendly image analysis software is readily available for purchase of license, its field training and project based applications. 
5. Seismic study for mines using advanced equipment is yet another new area developed at the centre for selection of mine machinery (e.g. P & S wave velocity determination using MASW)
6. CIMFR Nagpur has developed technical capabilities / expertise in “demolition blasting”, ‘Laketap blasting” and “Underwater blasting techniques” and successfully carried out projects in the immediate past.  
   
    
7. Geo-hydrological investigations related work for mines including dewatering issues are also undertaken by the Nagpur centre of CIMFR. (Protection measures for the cave paintings from deterioration due to seepage water)
   
8. Quantitative estimation of mine water, mine seepage calculation & modeling is yet another area developed at the centre for providing services to industry. 
9. Online remote vibration monitoring i.e. E-instrumentation of blasting operation in mines is another area under ‘new development’ category.
10. Rapid excavation techniques for hydroelectric caverns is fully developed and related scientific investigation studies are being undertaken by this Nagpur centre of CIMFR.
11. Conservation of mud paintings of historical importance from ill effects of conventional blasting at Alchi Monastry, Leh – Ladakh had been undertaken by the centre in the recent past 

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 .
