    The Mining Process Introduction underground COAL

    The Mining Process. Once a mining lease has been awarded to an operator, exploration (i.e. evaluation of the resource) takes place, followed by a planning and development process before excavation or mining begins. The initial task is to gain access to the seam from the surface by some means (shafts, drifts, etc – see Access to Seam from ...

    For instance, a royalty rate of 12.5 percent for coal to be mined by surface mining methods and 8 percent for coal to be mined by underground mining methods is required. There is a diligent development requirement that means commercial quantities of coal must be produced from the lease within 10 years of lease issuance.

    Jun 22, 2018 The mining process can be broken down into two categories: Surface Mining. Workers begin by striping the overburden, which is rock, soil, and ecosystem that lies above the surface. Underground mining. The digging of tunnels and sink shafts when the ore—or mineral deposit—is below the surface. Hand tools such as chisels, hammers, and wedges ...

    Coal Washing. Coal washing is a process designed to separate the coal particles based on size, density and shape. Achieved by allowing the coal to settle in the wash fluid. Continuous Mining. Continuous Mining is an underground method of extracting coal. The process utilises a machine that is capable of handling the entire extraction process.

    Commonly used mining techniques to extract coal ICSC

    Jan 25, 2018 In case of strip mining, coal seams are reached by removing the surface above them. The surface, which is referred to as overburden, is removed in long strips in this coal mining technique. The overburden taken out from the first strip is deposited outside the mining place. This process is referred to as out-of-pit dumping. The void resulting ...

    History of coal mining Wikipedia

    The history of coal mining goes back thousands of years, with early mines documented in ancient China, the Roman Empire and other early historical economies. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity. Coal mining continues as an important economic activity today ...

    Coal Wikipedia

    Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
