That means if the land we mine once grew crops, it must be able to do so again after reclamation. The cost to reclaim one acre of land averages about 20,000 and can run as high as 50,000. BNI Coal has also invested tens of millions of dollars in the equipment necessary for the reclamation process. We will continue to remain at the forefront ...
Mining activities produced a lot of abandoned mine land. This paper introduced the theoretical and technical progress of ecological restoration of surface coal mines, mining subsidence land and ...
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 ...
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.
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 ...
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...
The regulations in chapter VII of 30 CFR, consisting of parts 700 through 899, establish the procedures through which the Secretary of the Interior will implement the Surface Mining Control and Reclamation Act of 1977 (Pub. L. 9587, 91 Stat. 445 ( 30 1201 et. seq. )). Chapter VII is divided into 13 subchapters.
Mine reclamation is the process of modifying land that has been mined to ecologically functional or economically usable state. Although the process of mine reclamation occurs once mining is completed, the planning of mine reclamation activities occurs prior to a mine being permitted or started.
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 bonds are posted by mining companies to ensure successful completion of the process. Reclamation includes the following steps: contouring of land; placement of topsoil or an approved substitute on the graded area; reseeding with native vegetation, crops and/or trees; and years of careful monitoring to assure success. As surface ...
Underground Mining. Typical underground mining operations begin either by clearing a section along the hillside where the coal outcrops or by tunneling downward to reach subsurface coal (Skousen and Zipper, 2021).Roomandpillar mines progress by excavating linear channels into the coal seam and connecting the channels with rooms while leaving pillars of coal behind to support the ...
The Surface Mining Control and Reclamation Act (SMCRA) of 1977 is the primary federal law that regulates the environmental effects of coal mining in the United States. SMCRA created two programs: one for reclaiming abandoned mine lands and a second for regulating active coal mines. To learn about these programs, read the full text of the ...
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 ...
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%. •
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.

"The process has become politicized, and the NEPA process has become weaponized. The end result is costly permitting delays, increased land disturbance in mining costs, delayed reclamation, fuel ...
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.
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.
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 ...
Mine reclamation is restoring a mine site to its premining condition. It includes capping and sealing contaminated areas, planting vegetation, salvaging usable materials, and reclaiming land affected by mining activity. The first step in the reclamation process is to locate and secure the mine site, followed by submitting an environmental ...
WASHINGTON The Office of Surface Mining Reclamation and Enforcement has named the Thunder Basin Coal Company as the recipient of the 2023 Good Neighbor Award in recognition of its corporate citizenship at the Black Thunder and Coal Creek mines in Wyoming. The Good Neighbor Award is presented to a mine operator for successfully working with the surrounding landowners and the community while ...
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 ...
What is Mine Reclamation? Reclamation is the combined process by which adverse environmental effects of surface mining are minimized and mined lands are returned to a beneficial end use. End uses may be open space, wildlife habitat, agriculture, or residential and commercial development. Some components of reclamation include practices that ...

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.
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 ...
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.
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.
NRG has bonds totaling 112 million to restore the Jewett mine, a process that began in 1986, a year after mining began. Companies commonly do reclamation work even as they're still mining a site.
