2025617· What is Open Pit Mining? A Comprehensive Guide Open pit mining, also known as open-cast or surface mining, is a technique of extracting minerals from the earth by removing the overburden (the soil, rock, and vegetation above the mineral deposit) and mining the ore body from an open pit. It is employed when deposits are close to the surface, rendering …

Abstract The major cost associated with open pit mine operations is waste stripping. While the steepening of slope angles reduces the stripping ratio, and hence operational costs, it also increases the likelihood of failure. Major slope failures incur significant cost elements including clean‐up, disruption to mine operation, and damage to mining equipment and in some cases …
