SRC531 86-102mm Carbide Reverse Circulation Drill Bits for Sampling

 

Product Introduce:

A reverse circulation drilling method for drilling cuttings carrying drill cuttings through the inner bore of the drill rod and returning from the borehole to the ground.The liquid (gas) flow of the reverse circulation drilling is compared with the conventional circulation method called positive circulation, in which the flushing medium is fed into the bottom of the drill hole through the inner hole of the drill rod and returns to the ground along the annular gap outside the drill rod. The speed of return is high, and it is very strong to carry rock powder. Rocks that have been drilled at the bottom of the hole can be discharged in time and quickly return to the surface.

 

Adavantages:

1. In difficult condition such as loose soil, hard rock and plenty of water exists, sampling can be done well.
2. Indirect cost reductions gained from a simplified sampling process.
3. Using higher grade carbides for longer life;

4. Minimizes hole erosion in fragile formations
5. Drills faster through soft formations with less blockages
6. Requires less water than diamond drilling.

Working principle
The on-board compressor delivers power to a pneumatic reciprocating piston. The piston, in turn, drives a tungsten-steel drill bit which is purpose designed to be able to crush hard rock.
Similar to air core drilling, drill cuttings are returned to surface inside rods. We achieve this through the use of dual wall drill rods: an outer drill rod with an inner tube. When compressed air is blown through the rod, the volume displaces the air, lifting the samples to the surface.
Once cuttings reach a diverter at the top of the hole, they’re moved through a hose and around the cyclone, which slows the sample down. From the cyclone the sample goes over a splitter that delivers a percentage of the entire sample into a sample bag. The exploration drilling team then collect the samples aligned to the hole depth and lay them out for the client to log, and then transport to the lab for assay.

About us:

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.
