BILLINGS, Mont. (AP) — The U.S., Canada and several indigenous groups announced a proposal on Monday to address pollution from coal mining in British Columbia that officials say has been contaminating waterways and harming fisheries on both sides of the border for years.. The proposal would be executed through a century-old U.S.-Canada …
— In abandoned open-pit coal mines, surface water and groundwater form acidic waters with high concentrations of metal ions due to chemical interactions with ores such as pyrite, and the formation of acid mine drainage (AMD) is one of the major sources of pollution of world concern. For this reason, this paper reviews the formation …
— Mining affects fresh water through heavy use of water in processing ore, and through water pollution from discharged mine effluent and seepage from tailings and waste rock impoundments. Increasingly, human activities such as mining threaten the water sources on which we all depend.
— Mining activities are among the main sources of heavy metal contamination in the environment. To analyze heavy metal pollution of soils from coal mines in China, we assessed pollution and potential ecological risk, compared heavy metal concentrations between soils from coal mines and soils from metal mines and identified the relationship …
The book "Coal Mine Drainage Prediction and Pollution Prevention in Pennsylvania" had its origins as far back as 1979 when a two page letter by Pennsylvania's coal regulatory program was written to provide guidelines to mine operators and permit reviewers …

— The market value of coal mines has varied significantly since 2010. In 2011, its market value increased to 1.3 billion US dollars but gradually decreased to 571 million US dollars until 2015. By 2020, the market value was approximately 698 million US dollars (Garside, 2021)—the global market value of coal mining from 2010 to 2020.
— China's water resources are relatively scarce, in general, and water resources per capita are only a quarter of the world's average 1,2,3,4.Water resource problems are more prominent in the ...
— This study analyzed the sources of total metal elements using the positive matrix factorization (PMF) model and conducted human health risk assessment for adults and children using the health risk assessment model recommended by the United States Environmental Protection Agency (USEPA). According to the health risk assessment, As …
— The scientific basis for dust prevention and management hinges on a thorough understanding of the long-term characteristics of dust pollution. However, analyzing the characteristics of long-term dust pollution in open-pit coal mines has always been a void in research due to the effect of the mines' geographical location and …
— Understanding the characteristics of mine water quality in coal mining areas is a prerequisite for its treatment and utilization. The main source of mine water is groundwater that enters the mines through water-bearing fractures (Gu et al. 2021a, b; He et al. 2018; Xie 2014).The quality of mine water primarily depends on the original …
— Roughly 200 years of coal mining occurred in Appalachia before passage of the 1977 federal Surface Mining Control and Reclamation Act, which established standards for operating and reclaiming ...
— Coal dust is the main pollutant in coal mining areas. Such pollutants easily diffuse and are difficult to monitor, which increases the cost of environmental pollution control. Remote sensing technology can be used to dynamically monitor mining areas at a low cost, and thus, this is a common means of mining area management. According to …
— Monitoring heavy metals (HMs) across source distance and depth distribution near coal mining sites is essential for preventing environmental pollution and health risks. This study investigated the distribution of selected HMs, cadmium (Cd2+), chromium (Cr2+), copper (Cu2+), manganese (Mn2+), nickel (Ni2+), lead (Pb2+), and …
— With the development of technology, the concepts of "green" and "sustainable" have gradually been popularized in all walks of life. With the continuous development of the world mining industry, the efficiency …
framework for pollution prevention in opencast coal mining. In specifying the scope of this document, SEPA requested inclusion of the following: 1. A hydrogeological summary of the impacts that opencast mining operations can have on water quality, focusing on the quality of water which is likely to leach from the disturbed geological materials. 2.
— As the world's resources continue to be exploited, mining activities are giving rise to increasing environmental damage and pollution, of which mine dust pollution is considered to be one of the biggest threats to environment and public health (Entwistle et al., 2019; Hendryx et al., 2020a): Mine dust pollution not only leads to serious …

Grewar says there is a huge amount of water in the Mpumalanga coalfields. An estimated 360 megalitres (ML) a day of mine-impacted water would be generated if all those coal mines were to close. This could support about 6 000 ha of irrigated land. Treating mine water to irrigation standards would cut the costs considerably, says Grewar.
