High Impact Frequency Reverse Water Hammer / Water Well Drilling
Hammer
Reverse Water Hammer Introduction
Reverse Circulation drilling, or RC drilling, is a method of
drilling which uses dual wall drill rods that consist of an outer
drill rod with an inner tube. These hollow inner tubes allow the
drill cuttings to be transported back to the surface in a
continuous, steady flow.
Unlike diamond drilling, it compiles sample rock cuttings instead
of rock core. The drilling mechanism is most often a pneumatic
reciprocating piston called a hammer, which in turn is driving a
tungsten-steel drill bit, specifically made to be able to crush
hard rock.
The RC hammer is used to remove rock samples which are pushed
through the machine with compressed air. When air is blown down the
annulus (ring-shaped structure) of the rod, the pressure shift
creates a reverse circulation, bringing the cuttings up the inner
tube. When the cuttings reach a deflector box at the top of the
rig, the matter is moved through a hose attached to the top of the
cyclone.
The drill cuttings will travel around the cyclone until they fall
through the bottom opening into a sample bag. These bags are marked
with the location and depth of the place where the sample was
collected and can be transported directly to the assay lab for
analysis.
