The enforcement mechanisms SMCRA relies upon—prohibitions against selling coal or obtaining new permits—are now meaningless to many companies that do not want new permits and have no buyers for coal, making enforcement of reclamation standards even more difficult for s...
A method of mine land reclamation coupled with underground mining was proposed. • The influence of mining sequence on temporal and spatial development of surface subsidence was analyzed. • The reclamation rate of concurrent mining and reclamation (CMR) increased from 32% of traditional reclamation to 65%. •
Sludge was added to reconstructed mine substrates (RMS) to accelerate the reclamation process. The effect of sludge on plant growth, microbial activity, soil aggregate stability, and...
Coal resources have always been in a very important position in the structure of nonrenewable energy in the world [1,2].China is the main coal energy consumer in the word and coal mining has made great contributions to local economic development for years [].According to the statistics, seventyfive percent of the added value of global coal production comes from openpit coal mines.
Mining is one of the most important economic sectors in Indonesia. Mining products contribute up to 17% per year of Indonesia's total export value, and from several major mining products, coal mining contributes a value of % [].Data from verified resources and reserves as of December 2019 showed that coal mining had the potential to reach 88, and 25, million tons, respectively.

Reclamation. Technical Services. The Technical Services Section provides technical assistance to all other Division sections but primary work effort is directed at active mines. Their main responsibility is reviewing the technical aspects of permit applications. Staff provide field advice on technical mining issues and frequently meet with coal ...
For these companies, the reclamation process goes handinhand with the mining itself; as new mines are carved out, old soil and grass goes back into exhausted mines to build back the land.
Title IV of the Surface Mining Control and Reclamation Act of 1977 (SMCRA) created the AML Fund, which is funded primarily by a reclamation fee (also known as the AML fee) assessed on each ton of coal produced in the United States and that, among other things, provides funding to eligible States and Tribes for the reclamation of coal mining ...
Underground mining leads to surface subsidence, vegetation degradation and environment damage. In order to mitigate such negative influences, this study focuses on subsidence characteristics and reclamation methods of the second coal mine in Zhaogu mining area. Due to high groundwater table at the mine, postmining land is divided into submerged and damaged zones. Zone boundaries are ...
It is a significant order as abandoning of mines or improper land reclamation following mine closure has been a regular complaint of environmentalist and activists. ... (201819) regarding land restoration and reclamation of 52 opencast coal mines projects of Coal India Limited (CIL), the total mine leasehold area is square kilometres ...
Land reclamation is the process of bringing degraded lands back to a more natural state. ... The Office of Surface Mining Reclamation and Enforcement estimates that cleaning up these remaining sites will cost about billion. But because this budget estimate only includes mines that have been recorded, there may be far more abandoned coal ...
SMCRA requires coal mine operators to reclaim lands that were disturbed during mining and to submit a financial assurance in an amount sufficient to ensure that adequate funds will be available to complete reclamation if the operator does not do so.
The 1977 Surface Mining Control and Reclamation Act requires coal companies to clean up damage as they mine. When mining is over, the land must be put back to "a condition capable of supporting the uses which it was capable of supporting prior to any mining." That's not how it generally works in practice.
A Bloomberg News/NPR investigation found large coal companies used bankruptcy and asset transfers to move old mines to shaky new owners, putting at risk federally mandated land reclamation.
Mine land reclamation is the process of developing and utilizing land that has been damaged and abandoned by mining, reflecting the effectiveness of environmental protection. ... Some mediumscale coal mine pilot units have made further progress in green mine construction due to the investment of a large number of human, material, and financial ...
Mine Subsidence. Reclamation Process. When subsidence reports are received, staff will investigate the problem to determine if it was caused by an abandoned coal mine. Other potential causes of subsidence include rotting tree roots, water impoundment and drainage issues, broken utility lines, and improper preparation of building sites.
Lands disturbed by coal mining must be restored to a condition that can support the uses it could support before mining (or even make the land better). In the closeup images, the mined land seems to move over time. As the mining and beginnings of the reclamation process take place, we can see the digging and backfilling occurring.
While the successful reclamation of coal postmining land sites in Indonesia has been evaluated, no costbenefit analysis has been carried out on the reclamation of mined land, and the impact of the reclamation work has not been determined. The results of this case study indicate that reclamation work is not an emissionfree process, but that the benefits delivered from this work are considerable.
Acid mine drainage is the most severe and wellrecognized environmental problem related to coal mining and can impact surface waters, including lakes, ponds, creeks, and even entire watersheds. AMD is water typically with a pH less than 4 that drains from mine workings and from mine spoils, and coal refuse (called acid rock drainage).
RECLAMATION Reclamation planning is an integral part of the entire mining process and begins before excavation is started. As discussed in Chapter 5, reclamation prac tices are, by definition, regulated by the SMCRA, which established minimum national standards for coal mining.
Coal mine site reclamation February 2013 Report number: CCC/216 Authors: Lesley Sloss IEA Clean Coal Centre Abstract and Figures Coal mine sites can have significant effects on local...
Reclamation of land disturbed due to mining in arid and semiarid environments occurs across the globe. Largescale surface mines provide unique opportunities to examine the reclamation process across a landscape. The objectives of this research were to (1) measure infiltration rates in reclaimed surface coal mines and (2) determine the effects of soil properties on ground cover on infiltration ...
(1) Persons engaging in coal exploration or surface coal mining and reclamation operations on Federal lands shall provide access for any authorized officer of OSM, the regulatory authority, and, as applicable, the Bureau of Land Management or the appropriate Federal land management agency to inspect the operations, without advance notice or a ...
A proposal in Congress last year would have provided 385 million a year for a decade in general tax dollars to reclaim new mines that coal companies, bonds and reclamation funds were supposed to ...
Green Forests Work. Such aggressive bulldozing is part of a new and evolving approach to healing forests destroyed by decades of surface coal mining in Appalachia, from Alabama to Pennsylvania. These lands were supposed to have been reclaimed in recent decades under the 1977 federal Surface Mine Control and Reclamation Act.
