Mineral Exploration

Regional geological and structural mapping are carried out for locating the potential coal/mineral bearing zone using hyper spectral satellite data for detail exploration planning.

Geostructural mapping for locating potential coal bearing zone in N-W part of IB Valley Coalfield

Land Use Mapping

Land use/vegetation cover mapping of coalfields are carried out for creating geo environmental database and to assess impact of mining and associated industrialization on land environment by analyzing temporal satellite data.

Land use/vegetation cover mapping of Singrauli coalfield based on satellite data.

Land Reclamation Monitoring

Satellite surveillance for land reclamation of all the OC mines of CIL are carried out on annual basis for assessing the progressive status of mine land reclamation and for taking up remedial measures, if any, required for environmental protection.

Watershed Management

Hydrogeomorphic mapping for locating the potential ground water zone in different coalfields and other parts of the country are carried out based on satellite data.Watershed management study for effective utilization of water resources

Water resource survey and hydrological study.

Mapping of potential ground water zone in Karanpura Coalfield based on satellite data.

Reservoir Sedimentation Assessment

Data from space platforms play a significant role in reservoir capacity estimation surveys. In the recent past, Satellite Remote Sensing has emerged as an important tool in carrying out reservoir capacity surveys rapidly, frequently and economically. CMPDI did the sedimentation assessment in Govind Ballabh Pant Sagar near Singrauli Coalfield at different periods.

Coal Mine Fire Mapping

Methodology for mapping coal mine fire using Airborne Thermal Scanner (Daedalus-1268) data was first developed by CMPDI in collaboration with NRSC, Hyderabad way back in the year 1992 in India. Coal mine fire mapping is being carried out using ASTER thermal band data for Jharia, Raniganj , Bokaro and Karanpura coalfields on annual basis and Fire Management Information System (FMIS)is developed to monitor the fire dynamics.

Sodic Land Mapping

About 2.04 million hectare land of the country is affected by soil salinity/ alkalinity. Due to excess use of chemical fertilser and canal irrigation, soil salts precipitated at the surface and made the land barren. CMPDI has developed the methodology for cadastral level sodic land mapping based on high resolution satellite data for UP Bhumi Sudhar Nigam Ltd. Sodic land mapping in Pratapgarh and Allahabad districts was carried out as pilot project for UPBSNL.

Site Selection for TPS, Washery & route alignments

CMPDI has established a methodology for locating the potential TPS sites numero uno using Geo Spatial technology in India for Central Electricity Authority, Govt. of India. More than 100 TPS & UMMPs sites are located by CMPDI including pit heads, load centers and coastal areas. Most of the UMMPs are coming on the sites selected by CMPDI.
