The mining method selection for underground mining can be described as a multi-criteria decision-making process, as several factors are involved in the selection process. In this paper, a methodology for rational and optimal mining method selection for underground mining of metallic mineral resources has been developed.

Underground mining is the process of extracting valuable minerals or other geological materials from beneath the Earth's surface. This method is often used when minerals are located deep underground, making surface mining impractical or inefficient. By accessing resources through shafts and tunnels, underground mining allows for the recovery of high-grade ores that may …

Underground mining is practical when: 1. The ore body is too deep to mine profitably by open pit. 2. The grades or quality of the orebody are high enough to cover costs. 3. Underground mining has a lower ground footprint than open pit mining. The underground mining methods we use include room and pillar, narrow vein stoping and large-scale ...

You will recall from Lesson 4.3 of Module 4 that underground mining methods are traditionally placed into three classes: unsupported, supported, and caving methods. These classes reflect the competency of the orebody and host rock more than anything else. If you excavate an underground opening in the ore or the rock, is the opening stable -- i ...

2) For artificially supported stopes, the available methods are shrinkage stoping, cut-and-fill mining, square-set mining, and longwall mining. 3) For caving methods, the available techniques are sublevel caving and block caving. Due to the uniqueness of each ore deposit, the variations on each of these methods are nearly limitless.
