Reverse Circulation drilling, or RC drilling, uses rods with inner and outer tubes, the drill cuttings are returned to surface inside the rods. The drilling mechanism is a pneumatic reciprocating piston known as a hammer driving a tungsten-steel drill bit.
Reverse circulation is achieved by blowing air down the annulus of the rod, the differential pressure creating air lift of the water and cuttings up the inner tube which is inside each rod. It reaches the deflector box at the top of the drill string then moves through a sample hose which is attached to the top of the cyclone.
Product specifications: re542 RC Bits
1.Direct drilling cost reductions in the range of 25% to 40%.
2.Faster completion of drill programs with quicker delivery of results.
3.Reduced man-hours at the drill with decreased exposure to potential accidents.
4.Reduced contractor activity in the mine reduces mine support burden.
5.Indirect cost reductions gained from a simplified sampling process.
6.Requires less water than diamond drilling.
SOLLROC Reverse Circulation drilling (RC) ,from size 3’’ to 5.5’’, is a technique of drilling that uses dual wall drill rods that consist of an outer drill rod with an inner tube. By using compressed air to extract rock fragments sample,the samples travel through rods to a sample splitter at surface, avoiding all contact between the samples and the borehole wall that allows samples to be retrieved with minimal contamination,which is mainly used in deep hole exploration and mining grade control.
