Understanding Underground Mining Methods
Underground mining is a method of extracting ore, minerals, and other geological materials from beneath the earth's surface. It is utilized when the mineral deposit cannot be recovered efficiently by surface mining, or when the deposit is located at a significant depth, thereby requiring a tunnel-based approach to reach it. ...

Types of Underground Mining Method Comparison
Shrinkage stoping refers to any overhand method in which the stope is kept full of broken ore until it is completed. The miners stand on top of the broken ore and work at the back. As broken ore takes up more space than ore in a solid mass, about 35 to 40 per cent, of it must be drawn to leave room for working.

12 Mining methods and method selection
Different mining methods are designed to produce different types and magnitudes of displacements, in the near-field and far-field domains of an orebody. For example, the mining method illustrated schematically in Figure 12.2 is designed to restrict rock displacements in both the near field and the far field of the orebody to elastic orders

OneMine | Underground In Situ Mining- A New Mining Method
Three years ago, an industry-supported research stud was initiated to determine whether a safer and more efficient (in terms of cost and environment) uranium mining method could be designed to replace existing techniques. As a result of this study, the "underground in situ" method was conceived and developed to the stage where it is now feasible.

In this method, you must drill a downwards ramp next to the ore deposit. This ramp should run from the surface level down as far as the ore deposit goes. Next, you can drill a horizontal cut from one side of the ore deposit to the other. Miners typically refer to such cuts as drifts.
