The mining industry continues to face the problem of depleting grades and the subsequent
significant variation in economic, environmental and technological characteristics have been …

In the commonly used underground mine planning framework, mine design is first
established and is the main input for the subsequent long-term mine production scheduling …

Reduced access to shallow mineral resources, increased demand for minerals, and
advances in technology have led to the development of deep underground mines. The …

Mineral extraction plays a key role in the global raw materials supply chain, however the
exhaustion of shallow deposits and typical scarcity of sampled data during exploration …

Stope layout optimisation is an important sub-problem of the generic underground mining
optimisation problem that contributes towards optimal ore extraction. It is a growing research …

Underground mining operations tend to have higher operating costs than surface mines.
When metal prices decrease, profitability is jeopardized due to the high costs. Therefore …

The Stope Boundary Optimization (SBO) problem refers to the layout design of production
areas (stopes) in an underground mining operation. It falls within the domain of strategic …

Stope layout optimization is an important feature of underground mining that maximizes the
economic value of the project while taking mining limits into account. The large number of …

Underground mining operations are sensitive to price fluctuations because they usually
perform with a narrow profit margin compared to open-pit mining. Furthermore, the economic …

Purpose. This study aims to enhance the optimization approach by integrating stability
analysis using Mathews Stability Graph into stope mining-level optimization algorithm …
