Near-Surface Geophysical Characterization of an Alluvial Aquifer - borehole extraction Archives - International Mining
holes in alluvial aquifers is perceived to reduce porosity and restrict flow paths, which results in permeability impairment and reduced borehole performance. This movement may occur at different stages in the life of the borehole, giving rise to drilling damage, development damage, and operational damage.

Borehole mining consists of two pipes one for pumping down high pressure water and another that delivers slurry back to the surface. A BHM tool consists of water jet pump, hydro monitor section, an extension section and a hub. The tool is lowered into a well until the hydro monitor reaches the depth of the hole where the borehole mining is started.Borehole and Surface Geophysics | Drilling | Layne.
