Coal mining subsidence is a common human geological disaster that was particularly conspicuous in China. It seriously restricts the sustainable development of …
The surface coal mine of China is mostly in the ecological environment fragile zone, and coal mining inevitably leads to a further deterioration of the ecological environment in mining areas. China faces the task of land reclamation and ecological restoration, which becomes a focus of researches. Based on the case study of North antelope Rochelle …
Millions of Americans nationwide live less than a mile from an abandoned coal mine. The Bipartisan Infrastructure Law allocated a total of $16 billion to address legacy pollution, including $11.3 billion in abandoned mine land funding over 15 years, facilitated by the Office of Surface Mining Reclamation and Enforcement. This historic …
Description of the dataset showing extent of coal resources capable of being extracted by surface mining methods.
By identifying surface mine disturbance information within China, the present study both addresses the lack of surface coal mine-specific data and the lack of time-series information in the process of surface destruction by mining development.
Surface mining, as the name suggests, involves the removal of minerals and materials from the Earth's surface. This method is employed when valuable resources, such as coal, minerals, metals, or aggregates, are found relatively close to the surface. The process is fundamentally different from subsurface mining, which involves digging …
The value of national coal deposits is determined for the Solid Fuel Energy Resources Assessment and Research Project through economic evaluations using hypothetical mining models. Deposits near the surface are evaluated with the U.S. Geological Survey (USGS) surface-mining model, which is patterned after the standard mining techniques and …
This report outlines a framework for the estimation of operating costs in surface coal mining projects. The cost estimation process makes use of the first-principles approach and is developed by breaking the mining operation into different activities. From this, a framework is developed for estimating costs against each activity or component.
Gevra OC Mine in Chhattisgarh, was the largest surface coal-producing mine in India, producing approximately 47.1 million tonnes of coal and an estimated 49.04 million metric tons per annum (mmtpa) of Run-of-Mine (ROM) in 2021. The Gevra OC Mine is owned by Coal India Ltd, and is due to operate until 2028.
This paper attempts to predict the surface subsidence induced by multi-seam longwall mining in the PT Gerbang Daya Mandiri (GDM) underground coal mine in Indonesia.

Land use impacts are commonly quantified and compared using 2D maps, limiting the scale of their reported impacts to surface area estimates. Yet, nearly all land use involves …
Impact of ground surface subsidence caused by underground coal mining on natural gas pipeline
Here, Chad Montrie examines the twentieth-century movement to outlaw surface mining in Appalachia, tracing popular opposition to the industry from its inception through the growth of a militant movement that engaged in acts of civil disobedience and industrial sabotage.
Coal mining has contributed to a solid and stable global economy. Surface mining and underground mining are the principal methods for extraction of co…
Surface coal mining has had a dramatic impact on the Appalachian economy and ecology since World War II, exacerbating the region's chronic unemployment and destroying much of its natural environment.
Mining is a competitive business with many players. The survival of a mine in the business is determined by its efficiency and cost-effectiveness relative to the other producers. …
Surface coal mining in the Mongolian Plateau destroyed or damaged more than 10,000 km² of natural vegetation and agricultural land, and consumed more than 2,315 million m³ of surface water and ...
This collection of fact sheets and other resources from the Office of Surface Mining Reclamation & Enforcement presents information about nationwide programs that fulfill …
The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on …
WASHINGTON – The Office of Surface Mining Reclamation and Enforcement today announced nearly $6 million in fiscal year 2023 funding from President Biden's Bipartisan Infrastructure Law to create good-paying jobs and catalyze economic opportunity by reclaiming abandoned mine lands (AML) in Iowa.
Surface mining allows the removal of coal from the surface rather than through underground tunnels. It requires the stripping away of earth, rock, and vegetation (collectively known as overburden) from above the coal deposit, which can then be mined and trucked away. Often referred to as strip mining, the practice has a history of …
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.
Future studies need to focus on more in-depth integrative assessments of environmental, economic, and social impacts of surface coal mining to seek sustainability solutions for the region.
Here are the ten largest surface mining projects by production in the Middle East and Africa in 2020, according to GlobalData's mining database.

Coal mining subsidence is an important factor of surface landscape distribution. With the increase of the subsidence depth, nutrients in soil, water, and ground broken extent will significantly change, resulting in certain disciplinary change of land use direction and manner according to subsidence depth.
This part provides for the regulation of surface coal mining and reclamation operations on Federal lands.
Underground coal mining, like many other human activities, cannot be conducted without some impact on the environment. For underground coal mining, particularly longwall mining, obvious impacts are often seen at the surface, in the form of subsidence.
Abstract This paper covers the entire lifetime of an underground coal mine, including the start-up of the mining oper-ations and the period after the closure and sealing of the underground workings. Measurements of the vertical surface movement are presented for three neighbouring mines in the Belgian Campine coal basin, where the longwall …
Wyodak Resources Development Corp., a subsidiary of Black Hills Corp. (NYSE: BKH), is a surface coal mine near Gillette, Wyo., and is the oldest operating surface coal mine in the United States. Wyodak has reserves of 213 million tons — a 40-year supply at expected production levels — in the Powder River Basin. Black Hills …
Here, we provided a novel approach to assess the dynamics of VCS affected by large-scale surface coal mining and subsequent restoration.
In this study, six areas of the Haizhou surface coal mine dump in Fuxin, China, were reclaimed with similar reconstruction techniques; however, differing vegeta-tion types were studied to compare the characteristics of soil macropore radius and preferential flow.
Coal is mined in Appalachia by both surface and underground mining techniques. Surface coal mining methods in the steep terrain of the central Appalachian coalfields include mountaintop removal, contour, area and highwall mining. Coal mining operations are found in Kentucky, West ia, ia, Maryland, Pennsylvania, Ohio, …
Advantages of surface mining include economic and financial benefits for miners and communities and a safer alternative to pit mining, but its disadvantages include environmental impacts, such as erosion and contamination. Surface mining, also called …
Casting design for bench blasting in surface coal mines is a new focus and a fairly recent success. This study aims at the development of a mathematical model to predict the throw of overburden material based on geological conditions of a bench and charges in blast holes. The procedure, derived on the basis of blasting theories and dynamics of the …
Coal mining - Prospecting, Exploration, Mining: The fundamental objective of coal prospecting is to discover coal resources through a search. In areas where coal mining has not been previously practiced, the search process should result in obtaining coal samples that give reasonable evidence of the existence of a coal seam. Once a …
