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.
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.
The operation plan sets forth a process by which coal will be mined and all the requirements of the reclamation plan are implemented. Unlike any other type of mining reclamation, coal mine reclamation is contemporaneous with the removal of coal. There are strict provisions that limit the amount of disturbance without corresponding reclamation.
The OSMRE Abandoned Mine Land (AML) Reclamation Program addresses the hazards and environmental degradation posed by legacy coal mines. While AMLs can be dangerous and unwelcoming, through reclamation, this land can find a new purpose.

Are blasting activities regulated at coal mines? Yes, the Land Reclamation Program regulates several aspects of the use of explosives at coal mines. These are. ... As of June 30, 2006, there were two operating coal mines and five in the process of reclaiming, along with eight that had their permits revoked and the Land Reclamation Program is ...
Nova Scotia Environment, Guide for Surface Coal Mine Reclamation INTRODUCTION: Coal has been mined in Nova Scotia for over 300 years. Surface and underground coal operations have made significant economic contributions to the province, including fuel, steel manufacturing and electrical generation. Excavation is the primary means for
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.
Reclamation Bonding Process SMCRA provides that, as a prerequisite for obtaining a coal mining permit, a person must post a reclamation bond to ensure that the regulatory authority will have sufficient funds to reclaim the site if the permittee fails to complete the reclamation plan approved in the permit. To remain qualified, selfbonded ...
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 ...
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.
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.
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 ...
Land reclamation in coal mining areas is a longterm dynamic process, and its ecosystem structure and function require a certain amount of time to develop, stabilize, and then reach maturity (MorenoMateos et al., 2020). ... Instead, studies should be based on key stages of the land reclamation process, such as the initial period, development ...
Figure A typical coal mine reclamation process includes filling in the pit after coal removal (top), recontouring to fit the adjacent landscape (middle), and then seeding with desired plant species (bottom). Photographs courtesy of M. Anne Naeth, licensed under a CC BY (Attribution) license.
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...
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 mine permittees pay a fee to the AML Reclamation Fund (AML Fund) based on the tonnage of coal produced. As of September 30, 2022, approximately billion in industry AML fees have been collected, including interest earned.
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 ...

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.
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. 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 ...
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.
During mine development, the operator will determine whether mining will allow for reclamation of areas where mining is completed concurrent with ongoing mining in adjacent areas. Reclamation efforts, including, but not limited to, backfilling, grading, topsoil replacement and revegetation of all land that is disturbed by surface coal mining ...
The reclamation process for all surface mining—including coal, bentonite, and trona—is very similar. When mining begins, the top soil—the top layer of fertile soil in which plants grow—is removed and saved for later use. The overburden—the soil that covers the mineral—is also removed and saved. Once mining operations are finished ...
Surface roughness can be achieved by reduced smoothing and "treading in" of the surfaces during the reconstruction process, ... Zipper C (2000) Coal mine reclamation, acid mine drainage, and the Clean Water Act. In: Barnhisel RI (ed) Reclamation of drastically disturbed lands, 2nd ed. Agron. Monogr. 41.

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 ...
The findings could lead Congress or the Department of the Interior to take steps to make sure unreclaimed mines get reclaimed, she said. The lawmakers have asked GAO to quantify the number, location and size of coal mines that have neither produced coal or made reclamation progress, and whether bonding or other financial assurances are adequate to address the problem.
The massive coal mines on the central part of the Navajo Nation have been closed for years. But along the dirt roads, you can still find signs warning of explosives. ... So Horseherder said if the mines impacted groundwater, that needs to be addressed in the reclamation process. "The water doesn't just affect the people that live in the ...
