  • Intelligent valve actuators in the mining industry

    Overview In mining, as in other hazardous industries, flow control equipment makes a vital contribution to efficiency and safety. Numerous operations, both on the surface and underground, depend upon the reliable control of fluids and gases which is generally achieved using valves, actuators and associated equipment. Underground areas of application include pumping stations, ...

  • 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, ...

  • Position Brief on oil sands mining in Canada

    Background The oil sands (also called tar sands) in Canada are the second largest petroleum deposit in the world after Saudi Arabia and underlie about 140,000 square kilometres of land in northern Alberta, composed of woodlands and wetlands. Wetlands cover roughly half the landscape of the oil sands region and a vast majority of these wetlands are peatlands. Oil sands development has ...

  • 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, ...


  • CSP and mining in Chile

    With a mining industry that produces 35% of the world´s copper, it is imperative for Chile´s economic growth to produce energy from a source that is secure, dispatchable and unlimited. In an exclusive online webinar last week, hosted by CSP Today, experts discussed the positive impact that solar CSP could have on Chile’s mining industry. With many mining markets located in ...

  • Coal combustion products in Europe - sustainable raw materials for the construction industry

    The production of coal combustion products (CCPs) in all the European member states is estimated to be about 100 million tonnes. The utilisation of CCPs is well established in some European countries, based on long term experience and technical as well as environmental benefits. The CCPs are mainly utilised in the building material and construction industry as a replacement for natural resources. ...

  • 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 ...

  • GenRel: A computerised model for reliability prediction of mining machinery

    This paper discusses ongoing research regarding the application of theoretical probability distributions to a reliability assessment model called GenRel. GenRel is a computer model for reliability analysis of mining equipment based on Genetic Algorithms (GAs). The reliability changes over time due to several covariates/factors (e.g., equipment age, operating environment, repairs). In our model, ...

  • 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 ...

  • Europe’s Largest Mine Gas Plant

    GE Jenbacher has supplied 14 cogeneration systems to Europe’s largest coal mine gas plant, Fenne, which is owned by SaarEnergie and located in the district of Fenne near Saarbrücken, Germany, GE Energy announced at Hannover Messe 2004. The JMS 620 GS cogeneration systems produce more than 40 megawatts of electricity and nearly 41 megawatts of thermal energy. This coal mine gas plant ...

  • Cleaner Production in the Mining Industry: Mount Isa Mines

    MIM Holdings Limited has implemented a program of innovations which has enabled the company to open a new mine and add new electricity-using activities while cutting total annual electricity use and carbon dioxide emissions. MIM has committed to the Australian Governmentís Greenhouse Challenge. This Federal and State Government sponsored initiative requires companies to reduce emissions of carbon ...


  • 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 ...


  • Comparison of Gas and Water Pycnometry of Coal Mine Wastes

    Coal mine washery wastes comprise two major components whose specific gravities differ markedly. Consequently, their specific gravity is much more variable than that of natural soils and is determined relatively frequently. The specific gravity of coal mine wastes is determined more rapidly and efficiently by gas pycnometry than by water pycnometry. However, the two methods give significantly ...
