Preliminary assessment of expediency of application of open pit operations
Authors:
Abstract
The most common way of determining the boundaries of open pit operations is to determine whether the contour stripping ratio is equal to the economically acceptable one, which is found by comparing open pit and underground mining. However, in the case of significant sediment load, this methodology can lead to incorrect conclusions, since the boundaries determined according to this method do not take into account the mining capital required to put the open pit into operation, which depends on the sediment load ...
