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.

Famous quotes containing the word process:
“The process of discovery is very simple. An unwearied and systematic application of known laws to nature causes the unknown to reveal themselves.”
—Henry David Thoreau (1817–1862)
“Thinking is seeing.... Every human science is based on deduction, which is a slow process of seeing by which we work up from the effect to the cause; or, in a wider sense, all poetry like every work of art proceeds from a swift vision of things.”
