Open-Pit Mining: A Comprehensive Guide
Open-pit mining, or opencast mining, is a surface mining technique used for large-scale operations. It involves extracting minerals from a pit by removing waste rock and overburden. Commonly used for minerals like copper, gold, and iron ore, requires heavy equipment such as trucks and shovels to efficiently extract the ore.
Open-Pit Mining | Method and Process | Epiroc US
Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.

Strategic mining options optimization: Open pit mining, underground
Also, in the concurrent open pit and underground mining scenario, the optimizer prefers extracting blocks using open pit mining. Although the underground mine could access ore sooner, the mining cost differential for open pit mining is more than compensated for by the discounting benefits associated with earlier underground mining.

Calculating ultimate pit limits and determining pushbacks in open-pit
A critical component to any feasibility study of an open-pit mining project is determining the ultimate pit limits and the optimal mining phases (pushbacks). Today, block models are the most commonly used technique for calculating mineral resources and reserves ( Krzemień et al., 2016 ; Riesgo García et al., 2019 ; Sterba et al., 2020 ).
