REVERSE CIRCULATION Functionality TOOLING         

Reverse Circulation (RC) drilling is utilised to accumulate rock samples rapidly and successfully employing a large rotary drill and CZPT. The substantial speed and reduced cost for each meter of RC drilling can make it perfect for obtaining mineral samples in the early phases of an exploration venture.

Principles of Reverse Circulation Drilling

RC drilling utilizes rods with inner and outer tubes, the drill cuttings are returned to area within the rods. The drilling mechanism is a pneumatic reciprocating piston recognized as a hammer driving a tungsten-steel drill bit.

RC drilling utilises a lot bigger rigs and equipment and depths of up to five hundred metres are routinely accomplished. RC drilling preferably produces dry rock chips, as large CZPTs dry the rock out forward of the advancing drill bit.

RC drilling is slower and costlier but achieves greater penetration than RAB or air core drilling it is cheaper than diamond coring and is therefore favored for most mineral exploration work.

Reverse circulation is attained by blowing air down the annulus of the rod, the differential pressure generating air raise of the h2o and cuttings up the inner tube which is inside of each rod. It reaches the deflector box at the best of the drill string then moves by way of a sample hose which is hooked up to the best of the cyclone.

The drill cuttings travel close to the within of the cyclone until finally they fall by means of an opening at the base and are gathered in a sample bag. For any drill hole there will be a large variety of sample baggage, each and every one particular marked to report the location and drilling depth that the sample was acquired.

The collected collection of sample bag cuttings are afterwards taken for analysis to establish the mineral composition of the drill gap. The analysis final results of every person bag represents the mineral composition at a particular sample stage in the drill hole. Geologists can then survey the drilled floor examination and make choices about the benefit of the total mineral deposit.
