  • 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 ...

  • Coal Bed Methane - A Global Market Scenario

    Coal Bed Methane (CBM) is a type of natural gas that is commonly extracted from coal beds located at depths between 300 to 1000 metres. This gas is an odorless, colorless mixture of a variety of gases, but with major share of methane – even upto 95% in many cases.  Browse: Coal Bed Methane ...


  • 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 ...

  • Clean coal opportunities are still growing mining history

    One of Northeastern Pennsylvania’s claims to fame is its overabundance of the natural resource anthracite coal. From the late 1800s to the middle of the 20th century, the anthracite mines of NEPA helped fuel the local economy and helped usher in the industrial revolution in the United States. Anthracite coal was heralded as the superior form of coal. It’s more pure, harder and has ...

  • 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 ...


  • Power generated from methane gas in disused mines in England

    Type     HOFGAS®-IPM/C 2500 Performance     2’500 Nm³/h / 520mbar dP Location     England (GB) Situation Mine gas is released when coal is extracted. This gas is sourced not only from working coal mines but also from those that were closed down long ago. Because large quantities of coal remain in the mine after it has ...

  • 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 ...

  • 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 ...

  • 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 ...
