The Process
- A borehole is drilled from land surface to a desired depth, where then actual borehole mining will take place.
- A casing column is lowered down the hole. Since BHM takes place in an "open hole", the casing shoe is located just above the upper border of the production interval (ore body) leaving the rest open.
- The BHM tool is lowered into the hole.
