  • Occurrence and Remediation of Coal Mine Bumps: A

    ABSTRACT One of the most difficult, longstanding engineering problems associated with coal mining is the catastrophic failure of cog mine structures known as bumps. For more than 70 years, researchers and practitioners have as- sembled a wealth of technical information on coal bumps in an attempt to understand and control them.

  • Abstract: The Deformation Metamorphism of Tectonic Coal

    Abstract: The Deformation Metamorphism of Tectonic Coal and Its Application in Geological Mining Hazards. CAO, YUNXING and LIU RUIXUN. Deformed coal is called tectonic coal which is further classified as cataclastic coal, granular coal, and mylonite coal. All three kinds of tectonic coal have generated dynamometamorphism during their deformation period. Compared with normal coal, their

  • Environmental Impact of Coal Mining on Water Regime and

    Abstract. Coal mining is one of the core industries that contribute to the economic development of a country but deteriorate the environment. Being the primary source of energy coal has become essen-tial to meet the energy demand of a country. It is excavated by both opencast and underground mining methods and affects the environment, especially water resources, by discharging huge amounts of

  • Distribution and environmental impact of coal-mining

    Abstract About 50 million tonnes/year of waste rock from coal-mining is generated in the limited area of the thickly populated Upper Silesian Coal Basin (USCB) in Poland. There are 380 coal-mining waste dumps, including 76 active dump sites covering over 2,000 ha. About 15-16 million tonnes/year of waste rock is being reused for civil

  • Eco-restoration of coal mine overburden dump.

    Energy is needed for economic growth and more than 70% of the energy generation capacity in India is by using coal. The production of coal was 430.83 Mt out of which opencast contributed to around 373 Mt in 2006 with an estimated overburden removal of 600 million m3. In India, opencast mining is most prominent method of coal excavation. However, each year hundreds of acres of pristine forest

  • Coal Mining - an overview | ScienceDirect Topics

    Abstract. Coal mining under conditions of sufficiently high pore gas pressure can produce the hazard of dynamic failure of coal known as coal and gas outbursts. During an outburst, coal fragmentation occurs and the fragmented coal is projected into the mine opening, accompanied by a rapid release of gas. A dual porosity multi-component coalbed methane reservoir simulator has been coupled with

    ABSTRACT: Float coal dust is produced by various mining methods, carried by ventilating air and deposited on the floor, roof and ribs of mine airways. If deposited, float dust is re-entrained during a methane explosion. Without sufficient inert rock dust quantities, this float coal dust can propagate an explosion throughout mining entries. Consequently, controlling float coal dust is of
