Chronotopic Figurations of Coal Mining at Blair Mountain
… contested terrain for mountaintop removal mining, is an exemplar of Appalachia coal mining's uniquely American tropes. In 1921, roughly 8,000 miners were held up at Blair as they marched south to Logan to protest labor conditions and petition for the right to unionize southern coalfields. …

Surface Subsidence Due to Coal Mining in Illinois
… of the land surface has been associated with coal mining in Illinois since the early days of the industry. Investigations of subsidence damage began in Illinois more than 100 years ago. However, over the years there has been very little scientific or engineering documentation of subsidence …

Physiochemical Treatment Options for High-Conductivity Coal Mining Runoff
… specific conductance (SC) of Appalachian coal mining runoff waters has become a parameter of concern with the EPA due to its negative effect on aquatic life and water quality. In order to comply with the EPA guidance suggesting an effluent SC of 500 µS/cm, the Appalachian Research …

Towards sustainable water management in the context of coal mining in South Africa: A critical reflection of the ongoing Lephalale coal mining project
Even though mining plays a major role in the economic development of South Africa, its detrimental impacts pose significant constraints on local communities’ rights. Such is the case with the right to access to water. Mining is one of the biggest contributors to water pollution, which impacts …

Development of an Underground Automated Thin-Seam Coal Mining Method
It is predicted that coal mining in Southwest Virginia, and the economic stability that it brings to the area, will continue to decline over the next decade unless an environmentally sound, and economically viable means can be found to extract seams of high quality coal in the thickness range of 14 …

Long-term scheduling in underground coal mining using mixed binary programming
Recognizing the complexity of coal mining management, e.g., the scarcity of financial resources and the high level of uncertainty, a mixed binary programming model has been developed as an aid for generating production schedules which maximize the associated net present value. Defining the mine …

Stream functional response to mountaintop removal and valley fill coal mining
Mountaintop removal and valley fill (MTRVF) mining has become a widespread means of coal extraction in the central Appalachians. During MTRVF several hundred meters of overburden are removed to access coal seams, and excess rubble is dumped into adjoining valleys and streams. Filling valleys …

Phytoremediation: a tool for restoring land degraded due to opencast coal mining
This research set on a former reclaimed opencast coal spoil in Varteg Hills, South Wales, UK explores the phytoremediation potential of Alnus glutinosa (Alder), Betula pendula (Roth) (Birch) and Larix decidua (Larch), which are commonly used in UK land reclamation, to sequester metals: Zn, Cd, Mn, …

Risk mapping of eMalahleni municipal area with focus on coal mining impacts
Coal-mining in eMalahleni raises a number of environmental challenges, including coal fires, subsidence, acid mine drainage (AMD) and air pollution. Previous studies by a number of institutions, including the Council for Geoscience, have shown that the impact on the environment and on human health …

Risky business: A pentadic analysis of two West Virginia coal mining disasters
… was rocked with two devastating disasters in the coal mining industry. Despite the disasters, West Virginians could not just walk away from the mines, as they depended on the coal industry for jobs and tax revenue. West Virginia had built a purpose-driven orientation towards the coal industry …
