LAND RECLAMATION

• Opencast mining method necessitates excavation of land.

• This initially leads to degradation of land.

• Coal India, tries to bring back the lost greenery by continuous afforestationand other reclamation activities.

• The mine reclamation is being monitored by advanced techniques i.e. Satellite Surveillance

To have practical idea about

To assess the remedial measures required for land reclamation / restoration.

To utilize the reclaimed land for larger socio-economic benefits in a planned way.

Procedures:Satellite Data: Procurement of RESOURCESAT (LISS-IV) data from NRSA, Hyderabad (Government of India Undertaking).

Collateral Data: Procurement of Ancillary Data related to concerned OCP from coal company.

Satellite Data Processing: Data processed using ERDAS image processing software. Information stored on GIS Platform for temporal analysis.

Ground Truthing: Selective ground verification of land use classes to be validated in each project.

Report Finalisation: Report finalised and uploaded in websites of CIL, CMPDIL & concerned subsidiary.

Scope of the Satellite Monitoring :

• 163 OCPs are in operation in Coal India.

• 49 projects producing more than 5 Mm3 (Coal+OB) per annum being monitored once a year.

• 114 projects producing less than 5 Mm3 (Coal+OB) per annum will be monitored once in 3 years.

• Surveillance for 49 projects producing more than 5 Mm3 per annum has been completed during the year 2009.

Salient FindingsSalient FindingsStudy reveals that in all OC projects, plantation area, green coverage and backfilled area have increased.

Reclamation & afforestation have been done in every OC project.

Compared to 2008, land reclamation has increased in the year 2009.

Green cover has increased in all 49 OC mines in the year 2009 w.r.t year 2008.

Reclamation & Plantation

Extensive tree plantation programme is undertaken every year by the subsidiaries of Coal India.

Avenue plantation, plantation on the OB dumps, plantation around mines, residential colonies, available land is undertaken in existing as well as new projects.

Coal India planted around 73 millions of plants till date.

Coal India is committed to continue plantation which is a part of annual activities in each subsidiary.
