Open Cut and Underground Mining iMINCOHow is Opal Mined Opals Down Under

Open Cut Mining There are many differences between open cut and underground mining When minerals and deposits are found close to the surface and spread across a large distance the best way to mine is to use the open cut mining methodIn Queensland the majority of mines worked in recent years are large open cut operations Overburden is stripped from zones of ironstone boulder concretions Boulders are carefully removed from the ground for processing Heavy equipment has been used to open up most areas of old workings At Yowah underground methods are still applied with success Shafts are sunk until a prospective layer
