Surveying

 All types of Surveying jobs are undertaken by CMPDI using latest survey equipment viz. Terrestrial Laser Scanner (TLS), Differential Global Positioning System (DGPS), Electronic Total Stations (ETS), Gyroscope etc.

OBR / Excavation Measurement

OBR measurement in OC mines of different subsidiaries of CIL and outside clients, using Terrestrial Laser Scanner on regular basis.

Earth excavation in civil construction can also be measured with laser scanner.

Vegetation Cover / Land Use Mapping

Vegetation cover/ Land Use mapping of 19 major coalfields are being 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 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.

Mineral Exploration

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

Coal Mine Fire Mapping

Methodology for mapping of Thermal anomalous area due to 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.

Later, Coal mine fire mapping was carried out using ASTER/LANDSAT 8 thermal band data for Jharia, Raniganj, Bokaro and Karanpura coalfields on annual basis between 2012 to 2017.

Thermal Mapping of Chirimiri Coalfield is being carried out using Satellite Data since 2024

Recently, Drone acquired TIR Data was used for mapping of Thermal anomalous areas due to coal mine fire in Kuju OCP, CCL

Environmental Management Planning

Land use/cover pattern in core and buffer zone based on satellite data for EMP of mining projects as per MoEF mandate.

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.

Reservoir Sedimentation Assessment

Data from space platforms play a significant role in reservoir capacity estimation surveys. CMPDI conducted the sedimentation assessment in Govind Ballabh Pant Sagar near Singrauli Coalfield for different cut-off periods.

Siltation assessment in GBP reservoir

Sodic Land  Mapping

Due to excess use of chemical fertiliser and canal irrigation, soil salts precipitated at the surface and make 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.

Correlation Survey in Underground Coal Mine having Shaft Entry using Gyroscope

Gyroscope is used for transfer of Ground Coordinates into an Underground Mine having Shaft entry through Gyroscopic Survey.

Tunnel Alignment using Gyroscope

Tunnel Alignment in Udhampur-Baramulla-Srinagar Rail Link Project, J&K and Sivok-Rangpo Rail Line Project, West Bengal, using GYROMAT 3000.

Alignment Survey Using Gyroscope

Alignment of Systems in Navy’s Ship at Mazegaon Dock with the help of Gyroscopic System (March-April 2009)

Settlement Mapping

High resolution Satellite Data is used to map settlements for R&R.

Site Selection   for TPS, Washeries and other Industrial Units

CMPDI has established a methodology for locating the potential TPS sites using Geo Spatial technology in India for Central Electricity Authority, Govt. of India. More than 120 TPS & UMMPs sites were located by CMPDI including pit heads, load centers and coastal areas. Most of the UMMPs are coming on the sites selected by CMPDI.

Major project of National Importance

Topographical survey of 27 major coalfields on scale 1:5000 with 2m contour interval in plains and 3-5 in hilly terrains based on Remote Sensing Technique for detail exploration, mine planning and infrastructure development completed in association with Survey of India.
