The suggested method will replace the heavily traditional resources excavation, transportation, and utilization modes with a new mining model. This new idea will pioneer the development of fluidized mining technology and will help achieve clean, efficient, and eco-friendly exploitation of deep underground solid minerals.

Mining - Prospecting, Exploration, Resources: Various techniques are used in the search for a mineral deposit, an activity called prospecting. Once a discovery has been made, the property containing a deposit, called the prospect, is explored to determine some of the more important characteristics of the deposit. Among these are its size, …

Seismic methods provide high-resolution images of geologic structures hosting mineral deposits and, in a few cases, can be used for direct targeting of mineral deposits. Applications are not limited to only surface seismic surveys, but also include borehole seismic methods such as VSP and crosshole imaging. To date, tens of 2D and 3D …
