The mining industry is the key pillar of Peru's economy. Substantial inbound investment has flowed into the sector over the past 20 years, making Peru one of the most popular …
Mining - Underground, Safety, Techniques: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, …
From a historical perspective, precious mineral mining in Peru is steeped in humble origins. The first mineral prospectors were mostly locals who used manual panning techniques to recover gold fromplacer deposits. Recovering gold this way was a slow and arduous task that yielded few gains. To increase productivity…

The mining method selection is based on geological, geotechnical, economic, and other parameters, so the decision-making process is complex and challenging. In the past, the traditional mining method selection depended on the previous engineering examples or experience of experts or mining companies (Namin et al., 2022).

The mining process is used to separate rock or ore from surrounding rock. There are four main mining methods: underground, open surface (pit), placer, and in-situ mining.The method used depends on the type of mineral resource that is mined, its location beneath the surface, and whether the resource is worth enough money to justify extracting it.
Sub-level caving is an underground mining method used to extract large volumes of ore from bodies that are steeply dipping or vertical. It is a productive and cost-effective mining method preferred for relatively low-cost, low-grade and large mineral deposits. In sub-level caving, tunnels (sub-levels) are developed in the ore body, at …
