Mapping and sampling for real-time development of mine plans in high-grade, narrow-vein, underground mining

Geological methods, such as sampling and mapping are key components in all mining operations. In underground, narrow-vein mines they are of particular importance as a small deviation from the ore-zone can result in a large loss of ore and be challenging to correct. This paper describes protocols for geological sampling that can be integrated with mine plans designed for new selective underground mining technology. A multistage sampling and surveying approach comprise different strategies that are tailored to different stages of the mining cycle. Collected data will be used to refine resource models and mine plans in real-time, providing greater geological control, improved grade control, enhanced mine planning and increased efficiency of selective mining. Continuous mining technology with increased geological certainty in high-grade deposits has the potential to greatly improve the economic viability of small mining operations with the potential to supply raw materials within Europe.
