Reverse Circulation (RC) Drilling

Reverse circulation or RC drilling is a fast and inexpensive method of drilling, particularly compared to diamond drilling. A hundred metres or more of drilling is possible  a day. RC is a commonly used drilling method in the mineral exploration industry.

The speed of RC drilling means  the drill programme needs to be planned well ahead of drill schedule. The supervising geologist should also have sufficient experience to change the programme at short notice, if necessary.

RC drilling works by blasting air down an outer drill pipe using a high performance air compressor at the surface. An air-driven hammer at the end of the drill stem pounds a tungsten-iron drill bit against the rock, pulverising and breaking fragments away. The drill bit, stem and pipe continuously rotate as the rock is being hammered. Jets of air  are forced up the drill hole on the side of the drill bit.

Rock dust and fragments known as cuttings or chips are carried by the strong airflow up through the middle of the bit into an inner drill pipe. The air current is so strong that rock material can be brought to the surface from hundreds of metres down. When it reaches the surface, the dust and chips are fed into a cyclone splitter that slows the air flow down and divides the sample into small and large  samples.

We are a leading manufacturer of rock drilling tools, like DTH hammers and bits, DTH drill pipes, RC hammers and bits, tophammer button bits, coupling, cross bits, drill rods located in Germany, China(joint-venture).
