  • Draw rate optimisation in block cave production scheduling

    Abstract: Among the underground mining methods available, caving methods are favoured because of their low cost and high production rat Block caving operations offer a much smaller environmental footprint compared to equivalent open pit operations due to the much smaller volume of waste to be moved and handled.

    Block caving is an underground hard rock mining method that, as the name suggests, involves allowing an ore body to cave First, a large section of rock is undercut, creating a drawing point to collect the rock as it caves under the influence of gravity Then, the caving ore is collected into a previously developed series of funnels and access.
