  • Underground Mining Transportation & Haulage Systems

    The term “rope haulage” is used here to mean the use of hoists for pulling cars on grades or flat slopes where the grade is too steep for locomotives or the method in general use in the mine Conveyor systems have come into common use in coal mines during the past decadeThere is usually no direct connection from a mine railway to the mine's industrial siding or the public railway network, because of the narrowgauge track that is normally employed In the United States, the standard gauge for mine haulage is 3 ft 6 in (1,067 mm), although gauges from 18 in (457 mm) to 5 ft 6 in (1,676 mm) are usedMine railway Wikipedia

    Moving mining equipment across Australia or across the world can present significant challenges from a logistics and an operational safety perspective One Australian company has been recognised for its expertise in moving mining equipment from pit to port They say that effective planning is a key element of successful heavy equipment haulageThe haulage system employed to convey coal from the face to the outside, dates back to 300 B C, when slaves carried the mineral from the face to the consumer The British discovered coal on their island about 800 A D and they were the first people to make practical use of coal and make coal mining a successful operation The Britons carried cargoes of coal in their trading expeditions longMine Haulage Metallurgist & Mineral Processing Engineer

  • Underground locomotive haulage

    increased from 90 to 906 In the early years locomotives were used on existing haulage roadways Post nationalisation, construction and reconstruction often involved the newly adopted horizon mining principle, in which locomotive haulage roadways were driven at gradients of 1 in 400 or 500 (025% or 020%) in favour of the load Since then the20/07/2016· Overburden is removed prior to surface mining and replaced after the coal is taken from the seam Rampis the road way constructed mainly in an open pit mine for the passage of the machines, also in underground mining may be used to connect levels for haulage purposesSURFACE MINING – Mining Engineering Site
