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.
With the total reclaimed area being km 2, the reclamation rate is about %. This study provides a systematic solution and process for monitoring the disturbance and reclamation of surface coal mining in a large range with little known about the mines' location.
Abstract. This paper is devoted to the restoration of vegetation around mining areas on the example of two landreclamation zones in the Borodinsky coal mine during springsummer of . Analysis of vegetation in this area has shown that indicators of spontaneous plant diversity in plots No. 1 and No. 2 were considered moderate in both ...

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.
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...

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 law required coal companies to clean up the damage and restore the hills and creeks, a process known as reclamation. And there was supposed to be a backup funding plan.
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).
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 ...
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 ...
But as the sun sets on America's coal mining era, new reclamation projects are taking root, transforming scarred lands and contaminated waters into productive resources while creating jobs —...
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
This study provides a systematic solution and process for monitoring the disturbance and reclamation of surface coal mining in a large range with little known about the mines' location. It can effectively identify the mining disturbance and reclamation process which can also be extended to other areas, providing a quantitative assessment of ...
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 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.
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 ...
The land underlying them is also rich in coal, and surface mines operated on more than million acres in the region from 1977, when the federal Surface Mining Control and Reclamation Act was passed, through 2015. Many efforts to reclaim mined lands most often resulted in the establishment of grasses, shrubs, and nonnative plants.

Experts and scholars at home and abroad have conducted targeted research on the issues of subsidence areas, fly ash yards, barrows, contaminated soil and water in openpit ...
Maryland has industries like coal mining in its industrial past, which means it has legacy pollution now. ... adverse effects after the process has finished. ... Mining Reclamation and Enforcement ...
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.
The process to develop a reclamation plan with wildlife habitat as a primary end land use for the Cheviot Mine is described. Reclam ation for wildlife habitat and the results of on going wildlife monitoring on two ... Reclamation of open pit coal mines is carried out in a progressiv e fashion meaning that once minin g of the first pit developm ...
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.
