Download or read book Best Practice Guidance for Effective Methane Drainage and Use in Coal Mines written by United Nations Publications and published by UN. This book was released on 2016 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today coal supplies around 30 per cent of global primary energy and 40 per cent of global electricity. Coal extraction has become increasingly challenging as shallow reserves are exhausted and deeper seams, with significant content of methane, are mined. Societies are demanding and expecting safer mine working conditions, and greater environmental stewardship from the coal industry. The global coal industry, national governments, trade unions, and worker safety advocates are concerned that the frequency and severity of methane explosions, especially in emerging economies, are unacceptably high. Coal mine methane (CMM) only becomes flammable and creates an explosion hazard when allowed to mix with air. Methane-rich gases, generally containing 80 per cent to 95 per cent methane at underground mining depths, occur naturally in coal seams and are released as CMM when coal seams are disturbed by mining activities. Methane is an explosive gas in the range of 5 per cent to 15 per cent methane in air. The application of best practices for methane drainage and use is critical to reduce methane-related accidents and explosions that all too often accompany coal mining, while also contributing to environmental protection through reduction of greenhouse gas (GHG) emissions. Good mining practices need to be transferred to all countries to ensure that risks are managed professionally and effectively. No mine, even in the most developed countries, is free from safety risks. Regardless of location or mining conditions, it is possible to significantly reduce the risk of methane related incidents and explosions. Good safety practice in coal mines is to reduce explosion risk by preventing the occurrence of explosive mixtures and, where practical, by monitoring and rapidly diluting explosive mixtures to safe concentrations.

Download or read book Best Practice Guidance for Effective Methane Drainage and Use in Coal Mines written by United Nations. Economic Commission for Europe and published by United Nations Publications. This book was released on 2010 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coal mines are not only a safety management challenge but also a major source of greenhouse gas emissions. Methane release during coal mining creates unsafe working conditions in underground coal mines around the world. This Guidance is intended to provide a genuine contribution to improve mine safety practices at active underground coal mines, by supporting safer mining practices to reduce fatalities, injuries, and property losses, while encouraging the use of coal mine methane (CMM) to reduce greenhouse gas emissions and utilize otherwise - wasted energy resources.

Download or read book Coalbed Methane Scientific Environmental and Economic Evaluation written by Maria Mastalerz and published by Springer. This book was released on 1999-07-31 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coalbed gas has been considered a hazard since the early 19th century when the first mine gas explosions occurred in the United States in 1810 and France in 1845. In eastern Australia methane-related mine disasters occurred late in the 19th century with hundreds of lives lost in New South Wales, and as recently as 1995 in Queensland's Bowen Basin. Ventilation and gas drainage technologies are now in practice. However, coalbed methane recently is becoming more recognized as a potential source of energy; rather than emitting this gas to the atmosphere during drainage of gassy mines it can be captured and utilized. Both economic and environmental concerns have sparked this impetus to capture coalbed methane. The number of methane utilization projects has increased in the United States in recent years as a result, to a large extent, of development in technology in methane recovery from coal seams. Between 1994 and 1997, the number of mines in Alabama, Colorado, Ohio, Pennsylvania, Virginia, and West Virginia recovering and utilizing methane increased from 1 0 to 17. The Environmental Protection Agency estimates that close to 49 billion cubic feet (Bet) of methane was recovered in 1996, meaning that this amount was not released into the atmosphere. It is estimated that in the same year total emissions of methane equaled 45. 7 Bcf. Other coal mines are being investigated at present, many ofwhich appear to be promising for the development of cost-effective gas recovery.
Download or read book Coal written by National Research Council and published by National Academies Press. This book was released on 2007-12-21 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coal will continue to provide a major portion of energy requirements in the United States for at least the next several decades. It is imperative that accurate information describing the amount, location, and quality of the coal resources and reserves be available to fulfill energy needs. It is also important that the United States extract its coal resources efficiently, safely, and in an environmentally responsible manner. A renewed focus on federal support for coal-related research, coordinated across agencies and with the active participation of the states and industrial sector, is a critical element for each of these requirements. Coal focuses on the research and development needs and priorities in the areas of coal resource and reserve assessments, coal mining and processing, transportation of coal and coal products, and coal utilization.

Download or read book Improving Characterization of Anthropogenic Methane Emissions in the United States written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2018-08-25 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding, quantifying, and tracking atmospheric methane and emissions is essential for addressing concerns and informing decisions that affect the climate, economy, and human health and safety. Atmospheric methane is a potent greenhouse gas (GHG) that contributes to global warming. While carbon dioxide is by far the dominant cause of the rise in global average temperatures, methane also plays a significant role because it absorbs more energy per unit mass than carbon dioxide does, giving it a disproportionately large effect on global radiative forcing. In addition to contributing to climate change, methane also affects human health as a precursor to ozone pollution in the lower atmosphere. Improving Characterization of Anthropogenic Methane Emissions in the United States summarizes the current state of understanding of methane emissions sources and the measurement approaches and evaluates opportunities for methodological and inventory development improvements. This report will inform future research agendas of various U.S. agencies, including NOAA, the EPA, the DOE, NASA, the U.S. Department of Agriculture (USDA), and the National Science Foundation (NSF).
