RC drilling definition

RC drilling means the drilling method employing a rotating or hammering action on a drill bit which returns a sample to the surface inside the rod string by compressed air.

RC drilling means the drilling method employing a rotating or hammering action on a drill bit which returns a sample to the surface inside the rod string by compressed air. Sample quality is very good, particularly if the drill hole is dry.

RC drilling means the drilling method employing a rotating or hammering action on a drill bit which returns a sample to the surface inside the rod string by compressed air. The drill sample quality is generally superior to RAB.

More Definitions of RC drilling

RC drilling means reverse circulation drilling;

RC drilling means reverse circulation drilling method that produces chips rather that core, with minimal wall rock contamination seen in conventional rotary drilling;

RC drilling means a drilling method, abbreviated for Reverse Circulation percussion drilling, whereby a rotating hammer bit pulverizes the rock, releasing chips of rock that are brought to the surface inside of drill rods by compressed air.

RC drilling means reverse circulation percussion drilling in which the drill hole is advanced by the hammer action of the drill bit and where the circulation of compressed air used to bring the samples to the surface is reversed to the normal to reduce sample contamination;
