  • Underground Mining of Shallow-Dipping Orebodies in

    Many underground mining methods rely on blasted rock moving under gravity to report to extraction points. Mining of orebodies dipping between 20 45 degrees poses a unique challenge for mining engineers in that a dip angle in this range will not allow the movement of broken ore down the footwall to the mucking horizon utilising gravity. This is more so in cases where the natural angle of

The ore that will be mined at these four operations is planned to be processed within the permitted plant footprint area, where a new 600 000 tpa CIL plant will be established. This plant can be readily doubled to accommodate 1.2 Mtpa of oxide ore with a modest capital expenditure (by building a new CIL stream and purchasing an

  • Minrail’s new mining system aims at tough-to-mine

    Mining shallow-angle deposits those that lie at between 10° and 45°– has long been a perplexing problem in the mining industry. While the angle is too steep for mobile equipment on wheels, it’s not steep enough for muck flow. Dilution is hard to control and it can be awkward and difficult to secure the roof with bolts or screens. Typically, the angle results in slow development, low

    A comparison of shallow and deep mining T Anderson KGHM International Ltd., Canada Abstract The challenges unique to deep mining are well known. There are countless examples of underground mines that have gradually progressed downwards and been forced to reassess their engineering design as they did so. It is, however, less common to see two mines simultaneously mining the same orebody at
