  • Case study - Coal mine to methane energy project

    At the Oxbow Elk Creek Mine in Somerset, Colorado, methane was free vented from the mine for more than 100 years with an estimated $1 million per month of potential fuel being released into the atmosphere. Through a partnership with Aspen Skiing Company, the methane that was once vented into the atmosphere is now being used to generate electricity that is fed into the ...


  • Memory effect on hydrate formation and influential factors of its sustainability in new hydrate–based coal mine methane separation method

    This paper describes an experimental study on the memory effect in a methane–in–water system in which a hydrate was once formed and then dissociated. The 'memory effect' is found to be associated with gas hydrate nucleation. This study aims to investigate how memory effect in the hydrate nucleation process depends on the thermal and kinetic history (i.e., the nucleation pressure and temperature, ...

  • Evaluation for the reduction and utilisation of coal mine methane emission with AHP method and decision tree

    We used the analytic hierarchy process (AHP) method to construct an evaluation index system for the reduction and utilisation of coal mine methane (CMM) emission. We used the system to evaluate some coal mines in China and other major coal–producing countries. To simplify the process of evaluation, we established an evaluation model based on the evaluation data and on a decision tree. We ...

  • Coal Mining and Production Industry - Pollution Prevention Guidelines

    Introduction Pollution Prevention Guidelines to provide technical advice and guidance to staff and consultants involved in pollution-related projects. The guidelines represent state-of-the-art thinking on how to reduce pollution emissions from the production process. In many cases, the guidelines provide numerical targets for reducing pollution, as well as maximum ...

  • A Neural Model for SPM Concentration Prediction in Coal Mines

    ABSTRACT Coal mines are the major sources of suspended particulate matter. To implement any control techniques or to install any control equipment around the coal mines, ambient concentration of suspended particulate matter should be known. In this paper a model is developed to find the concentration of suspended particulate matter at various locations away from the source. The model is ...


  • Options to Reduce Methane Emissions

    This study analyses methane emissions in the EU and strategies to control them. It considers options for the reduction of emissions from each of the main source sectors, agriculture, waste, coal mining and the oil and gas industry, and assesses costs and applicability of the mitigation options available to produce cost curves for reducing emissions. The study also makes projections of methane ...

  • A preliminary study of the application of Background Oriented Schlieren (BOS) for the qualitative imaging of methane emissions from coal

    Methane presents a pervasive risk in most coal mines, its dilution being one of the primary objectives of the ventilation system. Although many different types of detectors and techniques exist for quantifying methane, little is known about the qualitative aspects of methane, such as visualising how this gas flows from coal. Background Oriented Schlieren (BOS) provides a potential method from ...

  • Donald Blankenship Charged in Mine Disaster

    Former chief executive of Massey Energy Company, Donald Blankenship, was charged for multiple violations of safety rules and deceit of federal inspectors that ultimately led to the death of 29 coal miners during a single incident in 2010; the deadliest mine incident since 1970. Indicted on four criminal counts by a federal grand jury in the Upper Big Branch disaster, Blankenship faces a ...

  • Case study - From mines to the slopes

    At ABUTEC, the only thing we like more than having fun is helping OTHERS have fun! That’s why we were excited about a project recently with the Oxbow Coal Mine in Somerset, Colo. For more than 100 years, Oxbow has been free-venting all of the methane from the mine, which ends up being approximately $1 million worth of fuel sent into the atmosphere with nothing to show for it. However, ...


  • Utilisation of Methane to Generate Electricity: BHP Appin and Tower Collieries

    Background BHP Collieries Division operates five underground coal mines in and around the Illawarra region of NSW. They include the Appin and Tower mines which are situated north-west of Wollongong and some 75 kilometres from Sydney. These two mines produce around 3.5 million tonnes of coal per year which is primarily used for domestic steel making. Some coking and energy coal is also ...


  • New Study Raises Big Questions on U.S. Fugitive Methane Emissions

    A new study in the Proceedings of the National Academy of Sciences sheds light on a question that continues to vex industry executives and policymakers alike: How significant are fugitive methane ...

  • Methane emissions and airflow patterns along longwall faces and through bleeder ventilation systems

    The National Institute for Occupational Safety and Health (NIOSH) conducted an investigation of longwall face and bleeder ventilation systems using tracer gas experiments and computer network ventilation. The condition of gateroad entries, along with the caved materials permeability and porosity changes as the longwall face advances, determine the resistance of the airflow pathways within the ...

  • Green Energy Applications Guide to Flow Measurement

    Provides technical discussion and illustrations for nine (9) different green energy and green-house gas flow measurement applications.  Includes landfill gas, biomass fermentation, wastewater digesters, on-farm biogas recovery, ethanol production/refining, coal mine and coal bed methane (CMM, CBM), biomass gasification, flare gas and flue gas.  Discussion includes overview of each ...

  • Triaxial Testing of Brittle Sandstone Using a Multiple Failure State Method

    The first phase of a recent research program undertaken to investigate sandstone/methane outbursts in coal bearing rocks required the use of a sandstone reference material in the development and trial of the testing procedures to be used. This was because the number of specimens of outburst-prone rocks from the affected mine was limited. Thus another goal of the first phase was to determine a ...

  • Climate change mitigation’s best-kept secret

    Methane is a potent greenhouse gas — but there’s a lot we can do about it. At Blue Spruce Farm in Bridport, Vt., the black-and-white dairy cows are used to the routine. In what looks like a choreographed dance, 1,400 milk cows delicately step over the scrapers that run along the concrete floors and collect their ...

  • Bicarbonate toxicity to Ceriodaphnia dubia and the freshwater shrimp Paratya australiensis and its influence on zinc toxicity

    Bicarbonate is often a major ionic constituent associated with produced waters from methane gas extraction and coal mining but few studies have determined its specific toxicity. Currently the environmental risk of bicarbonate anion in water discharges is assessed based on the toxicity of sodium chloride or artificial sea water and is regulated via electrical conductivity. Increased NaHCO3 ...

  • Fast Action to Reduce the Risks of Climate Change: U.S. Options to Limit Short-Lived Climate Pollutants

    Short-lived climate pollutants such as soot, methane and hydroflurorocarbons (HFCs) account for 30 to 40 percent of global warming to date. Targeted efforts to reduce these emissions can slow the pace of global warming and moderate climate impacts already underway, including the melting of sea ice and glaciers. By reducing local air pollution, such measures would also produce substantial public ...

  • Brades Rise, Sandwell case study - Development on a former dump site affects 40 terraced houses

    Brades Rise was originally a clay pit with a long history of municipal waste dumping, but given it was also adjacent to a factory had a significant quantitiy of industrial waste added to it. The pit was filled in and then became a sports ground.It was sold by a sports equipment manufacturer in the 1980s and in recent years has had several developers competing to build but planning applications ...

  • Manmade chemicals a major cause of global climate change

    Although the Earth?s climate evolves naturally over time, the major cause of climate change that is harmful and lead to unfavorable weather, water patterns, growth patterns are due to the release of manmade chemicals. While these chemicals are necessary to produce certain items, operate essential refrigeration equipment, or make our daily lives easier, they are a danger to the environment and the ...
