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, 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.
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 …
Coal mining generates a number of significant environmental impacts. Due to its synoptic coverage and repetitive data acquisition capabilities, remote sensing has been extensively used to monitor effects of surface mining. Availability of low cost and high resolution data in recent years has focused increased attention on the use of satellite …
The energy sources in mining operations. are diesel fuel, electricity, natural gas, coal and gasoline, with participation in total energy consumption of 34%, 32%, 22%, 10% and 2%, respectively ...
The research on mining-induced land subsidence has a rather along history. In China, the classical textbook published in 1991, Coal Mining Subsidence 16, had …
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 …
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.
Water pollution from surface coal mining has degraded more than 22 percent of streams and rivers in southern West ia to the point they may now qualify as impaired under state criteria ...
Solid backfill technology, which can control the strata movement and. prevent potential hazards, has been used as the primary method in deep mining for …
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 …
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 …
Surface subsidence can cause both damage to infrastructure and a number of different environmental problems. These include surface water accumulations, loss of farmland, cracks and other damage to roads and bridges, and, in the most severe cases, the collapse of house and other buildings. Surface subsidence can be especially severe …
This article deals with reliability analysis of mining equipment such as shovels and dumper in a surface coal mine at The Singareni Collieries Co. Ltd., Telangana, by using the RBD and Markov model. First, the method is to obtain the MTBF and failure rate of the individual subsystem of a shovel and each dumper using RBD. …
Study on surface subsidence forecasting system of nearly flat coal seam mining. Against the features of near level seam coal mining subsidence,the random medium theory is applied to make a predict research,considering the factors of mining geology and the impact of mining technology,a reasonable trade-off parameter predicted …
Surface coal mining generates alkaline mine drainage resulting 113 in dramatic increases in pH and specific conductivity (the standard measure of ionic strength in 114 aquatic habitats) of receiving streams.
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 …
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. …
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 …
Coal mining has contributed to a solid and stable global economy. Surface mining and underground mining are the principal methods for extraction of co…
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.
This collection of fact sheets and other resources from the Office of Surface Mining Reclamation & Enforcement presents information about nationwide programs that fulfill …
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 …
Remote sensing provides vital tools for surface-mining monitoring operations as well as for reclamation efforts in the central Salt Range of the Indus River Basin, Pakistan.
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 …
Coal mining subsidence is a common human geological disaster that was particularly conspicuous in China. It seriously restricts the sustainable development of …
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.
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 …
