    Open Pit Mining An Overview Sciencedirect Topics

    Open-pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow. Figure 8.8. Open-pit mine 16. Surface mining is usually used to develop coal seams and deposits of many other minerals, but their feasibilities vary with the nature of the body ore.

    A New Generic Open Pit Mine Planning Process With Risk

    Dec 17, 2016 It is common in mining industry that the deposits contain multiple correlated attributes of interest. A typical example is iron ore mining, where up to six variables need to be considered in resource estimation and mine planning, namely iron Fe, silica SiO 2, alumina Al 2 O 3, phosphor P, loss on ignition LOI and Ochreous Goethite GOL, and they are cross-correlated.

    Oct 17, 2018 A new mining scheme by employing the induced caving mining method to exploit hanging-wall ore-body during the transition from open pit to underground mining is proposed. The basic idea is to use the mined-out area generated by the planned mining of the hanging-wall ore-body to absorb the collapsed slope body, so as to avoid the influence of the inner-slope mining to the normal open-pit mining ...

    The ratio of waste rockore is called stripping ratio. For example, a stripping ratio of 21 means that 2 tonnes of waste rock needs to be removed to mine 1 tonne of ore. Generally, an open pit mine has a higher stripping ratio than an underground mine. Waste rock is often deposited in piles or heaps close to the mine to minimize transports.
