Boreholes - an overview | ScienceDirect Topics

Acoustic borehole televiewers require liquid-filled boreholes but operate better in OBM than do microresistivity scanners, provide full 360° image coverage of the borehole walls, which microresistivity scanners do not, and operate better in rugose boreholes than do microresistivity scanners. The time-of-flight data also allow three-dimensional information about the borehole wall.

Mineral deposit | BritannicaPrzetłumacz tę stronę

All ore deposits are mineral deposits, but the reverse is not true. Ore deposit is an economic term, while mineral deposit is a geologic term. Whether a given mineral deposit is also an ore deposit depends on many factors other than the level of concentration and the size of the deposit; all factors that affect the mining, processing, and transporting of the ore must be considered as well.

Borehole mining - WikipediaTraduire cette page

Borehole Mining (BHM) is a remote operated method of extraction of mineral resources through boreholes based on in-situ conversion of ores into a mobile form (slurry) by means of high pressure water jets (hydraulicking).This process can be carried-out from land surface, open pit floor, underground mine or floating platform or vessel through pre-drilled boreholes.
