Metal mining accounts for a substantial share of state revenue, and Indonesias mining sector was the fifthlargest contributor to the economy in 2018, earning (), or 8% of the national GDP of Rp14,837trn (), as per figures from Statistics Indonesia.
Approximately, 11 million tonnes of coal extracted over a 20 to 30 year period from this opencast mine in Merthyr Tydfil . The scheme at peak production extracts 20,000 tonnes of coal per week. The company itself advertises the project as quot;the Ffosyfran land reclamation scheme, a major opencast coaling operation.quot; Work at site began in 2007.
production planing of coal in open cast coal mine indonesia. Production planing of coal in open cast coal mine indonesia sep the machinery available with coal india ltd called opencast mining allows drilling mostly up to meters below earths surface but about of total coal reserves are located at a deeper depth which cannot be extracted using opencast mining moreover open cast mining is more
Reclamation of Degraded Landscapes due to Opencast Mining 827 many subcategories of impacts such as air pollution, ground deformation, water pollution and water resource depletion (Sengupta 1993; Younger 2004). According to Ghose (2002), opencast coal mining causes much more environmental
Chaulya, Prasad, in Sensing and Monitoring Technologies for Mines and Hazardous Areas, 2016. Abstract. Opencast mining operations involve huge quantities of overburden removal, dumping and backfilling in excavated areas. A substantial increase in the rate of accumulation of waste dumps in recent years has resulted in greater height of the dump for minimum ground cover area and also
Opencast nickel mining is common in natural forests of Indonesia. However, rehabilitation of postmining degraded land is difficult. We investigated the effect of opencast nickel mining on soil chemical properties and the growth of two fastgrowing tropical tree species, Falcataria moluccana and Albizia saman. Soil was collected from postnickel mining land and a nearby natural forest.
Reclamation processes. As part of the life cycle of a surface coal mine, completed mine areas must undergo mining ends, operators must restore the land to its approximate original contour (AOC) or leave the land graded and suitable for a higher and better postmining land use (PMLU) that has been approved as part of the original mining permit application.

Dec 17, 2015#0183;#32;Indonesia may also become a net importer of natural gas by 2020, leaving the government vulnerable to swings in global gas prices and hungry for a stable fuel supply in its backyard. The impacts of Indonesias coalmining sector could be eased if companies did better reclamation work.

Jul 24, 2012#0183;#32;Section 101(e) of SMCRA says: Surface mining and reclamation technology are now developed so that effective and reasonable regulation of surface coal mining operations by the States and by the Federal Government in accordance with the requirements of this Act is an appropriate and necessary means to minimize so far as practicable the adverse
The reclamation of surface (opencast) coal mines is not always successful; there remains a legacy of degraded land that burdens local communities. This article evaluates a communityoriented, lowcost means of geoecological regeneration, the Cradle for Nature strategy, which uses mosaic tree planting to foster positive natural ecological processes.
Surface mining is a global phenomenon. When dealing with the land disturbances caused by surface mining operations, the terms remediation, reclamation, restoration and rehabilitation (R4) are commonly used interchangeably or otherwise vaguely defined.
