5 Inches Reverse Circulation DTH Drilling Tools , Rock Drill Steel And Bits
Introduction of Reverse Circulation Drilling
Reverse Circulation drilling, referred to as "Centre Sample
Recovery" or "Dual Wall Drilling", employs a Dual Wall Pipe where
the drilling medium, normally high pressure air,is passed between
the outer and inner tubes down to the face of the drilling bit
where
it is returned up the centre tube along with the sample cut by the
drill bit.
The use and the advantages of the R.C. DTH Hammer:
1) No Contamination
The R.C. System collects sample through the recovery holes in the
face of the drill bit immediately as the cuttings or sample is
formed. The drilled sample does not have to travel the length of
the hammer where contamination and loss of sample takes place.
2) Higher Production
In broken and fractured ground conditions, the R.C. wi ll often out
perform the conventional hammer in terms of penetration rates.
3) Dry Sample
Even in certain water bearing stratas it is st ill possible to
collect a dry sample because the cuttings (sample) are collected as
they are formed through the face of the drill bit.
4) Higher Sample Recovery
Because the samp le is collected through the face of the drill bit
there is no loss of sample when drilling through broken or fract
ured ground. And since the bit matched to the chuck size, there is
very little bypass of sample and recovery rates of up to 98%
are generally achievable.
