UIM-2014 Application of Remote Sensing Satellite Data in Coal Exploration & Mining Shri N. P. Singh, General Manager (Geomatics) Central Mine Planning & Design Institute, Ranchi
UIM-2014 Remote Sensing in CMPDI/Coal India Remote Sensing Cell was set up in CMPDI way back in 1989 Remote Sensing started in Coal Industry with IRS 1A data Today we have grown to a well equipped Geomatics Division comprising about 40 scientists of multidisciplinary group Geologists Mining Engineer Civil Engineer Environmental Engineers Surveyors Computer Engineers Excavation Engineers
UIM-2014 All the scientists are imparted basic training in NRSC Specialized training are imparted in IIRS,GSI,Survey of India and USA under Indo- US programme. Equipped with ERDAS,Geomatica, Arc-info, LPS Using following satellite data ranging from visible to microwave LISS-III LISS IV Carto I & II IKONOS WorldView-2 ASTER Landsat 8 RISAT
Today Geospatial technology has made in road in all the stages of mining viz. Pre-mining, syn-mining and Post-mining. CMPDI is using almost all the satellite data ranging from visible to Microwave spectrum in different application in mining. CMPDI has also been bestowed Geospatial World Excellence Award -2012 and Best Enterprise using Geospatial Technology- 2013 in recognition of its excellent work carried out in the field of Geospatial Technology.
Application of Geospatial Technology In Coal Mining Topographical Survey Updated Topographical survey of all the major coalfields on 1:5000 scale with 2 m contour interval has been taken up in collaboration with Survey of India based on Remote Sensing data. Topo sheets will be prepared on GIS platform and will be used for detail coal exploration, mine planning and infrastructure development.
UIM-2014 Coal Exploration High resolution satellite data are used for regional geological mapping as well as for locating the potential coal bearing area for detail exploration
UIM-2014 Hydrogeomorphic mapping Coalfield wise hydrogeomorphic mapping for locating the potential ground ground zone are carried out based on geospatial technology for water supply
UIM-2014 Land use/vegetation Cover Monitoring in Coalfield Geo-environmental dada base for all the coalfields are created using geospatial technology and monitored at regular interval of three years to assess the impact of coal mining on land use/vegetation cover in the coalfield. Year 2000

UIM-2014 Land Reclamation Monitoring of OC Projects Land reclamation monitoring of all the 168 opencast are taken up by CMPDI at regular basis using high resolution satellite data and GIS from Year 2009. Mines which are producing more than 5 million cubic m. (coal +OB) are monitored on annual basis and less than 5mcm mines at interval of three years. Such monitoring helps in assessing the progressive status of mined land reclamation and mine closure and also to take up remedial measures, if any, required for environmental protection. Land reclamation monitoring of 50 mines (>5mcm capacity) carried out during year2013 indicates that about 50% excavated area are biologically reclaimed by plantation carried out on backfilled and OB dump. 30% excavated area is under backfilling and balance 20% area is under active mining. After completion of backfilling, area will be planted.

Thermal Infrared (TIR) Survey for Monitoring of Coal Mine Fire CMPDI has initiated the Satellite based Thermal Infrared (TIR) survey for mapping the extent of fire Mine Fire Information System (MFIS) has also been developed to monitor the latest status of coal mine fire in Jharia, Raniganj, Karanpura and Bokaro coalfields and direction of fire front movement to formulate the remedial measures. Mine fire monitoring being carried out by CMPDI regularly on annual basis in the above coalfields based on Thermal Satellite Data(ASTER/Landsat-8). Result of the study carried out based on 2013 satellite data reveals that area of fire has been reduced from 9.73 sq. km (2009) to 6.17 sq.km.(2013) in Jharia coalfield due to number of mitigative fire control measures taken by BCCL.
