A study of longwall subsidence in the Appalachian coalfield
… from case studies gathered from the Appalachian coalfields. Furthermore, based on this information, an empirical, predictive capability will be developed which can be used to provide accurate and reliable predictions of subsidence in this region.

Geology and petrography of the Wellington Seam, Nanaimo Coalfield, Vancouver Island
The Wellington Seam in the Nanaimo Coalfield of Vancouver Island has contributed significantly to British Columbia's coal production since its discovery in 1871. Difficult geological conditions and conflicts between surface land use and mining activities have hampered the efficient development of …

The Biopsychosocial Benefits of Walking Football in the Welsh Coalfield Regions
… to Great British city regions, the Welsh Coalfield regions experience distinct disparities relating to mental and physical health outcomes. These include, a higher number of older adults, a lower life expectancy, higher rates of disability living allowance, and incapacity benefit …

Making and Breaking Big Rural: Science and Technology Construct the Coalfield
… Big Rural: Science and Technology Construct the Coalfield examines science and technology research and its role in constructing a rural industrial space such as the Pocahontas Coalfield in Southern West Virginia/Southwest Virginia. It examines the ramifications of this single sector rural space, …

Update and sensitivity analysis of "Export and coking coal from the Checua-Lenguazaque (Colombia) coalfield"
Includes bibliographical references.

The prediction of surface subsidence due to room and pillar mining in the Appalachian coalfield
Most research on surface subsidence pertains to domestic as well as foreign experiences with longwall mining. Investigations into room-and-pillar subsidence have often been neglected, despite the fact that this is the predominant mining system in this country. However, the recent economic …

Geology and characterization of coal at the Mushithe Coal Occurrence, Soutpansberg Coalfield, Limpopo Province, South Africa
… Tshipise-Pafuri sub-basin of the Soutpansberg coalfield in South Africa. The Soutpansberg Coalfield has received comparatively less attention compared to other more notable South African coalfields. There is as a consequence very limited information in the public domain applicable to the …

Site Quality Classification for Mapping Forest Productivity Potential on Mine Soils in the Appalachian Coalfield Region
Surface mining for coal in the Appalachian region destroys native forests and replaces them with reclaimed landscapes that are often revegetated as grasslands and are unacceptable for managed forest production without extensive remediation. Tree survival and growth are dependent on many reclaimed …

Lithostratigraphic and Geochemical Characterisation of the Waterberg Coalfield: Implications to Acid Mine Drainage, Limpopo Province, South Africa
… conducted at Sekoko coal mine in the Waterberg coalfield of South Africa aimed to establish the quality of coal and its host rocks, as well as the potential for acid mine water generation. A total of 18 samples were collected from a box-cut and analysed using various methods such as, Scanning …

Levels of Dissolved Solids Associated with Aquatic Life Effects in Headwater Streams of Virginia's Central Appalachian Coalfield Region
Benthic macroinvertebrate communities in headwater streams influenced by Appalachian coal mining often differ from communities in minimally distrubed streams. Total dissolved solids (TDS) associated with mining have been suggested as stressors to these communities. In studies of such streams …

A coal camp and its classroom: a historical study of a Virginia coalfield community and its school 1888-1987
… briefly examine the history of the Pocahontas Coalfields. The school that was established in the community of Bishop was a direct result, not only of the agricultural community that preceded it, but also of the influence exacted upon the school by the coal company which created the Bishop camp …

Mineralogy and geochemistry of the carbonaceous mudstones and coal petrogenesis of the Grootgeluk formation in the Waterberg coalfield, South Africa
The Grootegeluk Formation in the Waterberg Coalfield consists of coal and mudstone layers that were deposited during the Late Permian. In the south-central part of the Waterberg Basin rapid subsidence resulted in the formation of strata (-70 m thick) which consist of relatively thin coal beds …

Comparison of Quantitative and Semi-Quantitative Assessments of Benthic Macroinvertebrate Community Response to Elevated Salinity in central Appalachian Coalfield Streams
Anthropogenic salinization of freshwater is a global concern. In freshwater environments, elevated levels of major ions, measured as total dissolved solids (TDS) or specific conductance (SC), can cause adverse effects on aquatic ecosystem structure and function. In central Appalachia, eastern USA, …

"Not just supporting but leading": the involvement of the women of the South Wales coalfield in the 1984-85 Miners' Strike
… that had been occurring since the 1960s in the coalfield communities of South Wales, and thereby contributed to a revision of the traditional notion of ‘communities’ which were changed by the very process of being defended.<br/>

Evaluating the role of flow and specific conductivity on stream metabolism across a mining-induced salinity gradient in the Appalachian Coalfield
… headwater streams in the Appalachian (U.S.) coalfields, where mining has resulted in widespread headwater stream salinization. Sites included a reference stream (REF) with SpC ranging from 0.2 - 57.69 μS/cm, a mid-salinity site (MID; 2.03- 594.7 μS/cm), and a high-salinity site (HI; 84.6-1920 …

The longer-term labour market and community impacts of deindustrialisation: a comparison of the Northumberland coalfield and the Monongahela Valley mill towns
… in two study areas; the Northumberland coalfield in Northeast England, and the Monongahela Valley steel towns of Southwestern Pennsylvania. Very different patterns of initial responses to job losses were observed between the two areas. These may be characterised as a distinction between …
