Product Description
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.
Features
Reverse Circulation hammer (RC hammer) is our most advanced product, used in deep hole exploration drilling and mining ore grade control, etc.
Characteristic:
- Reference the design and production experience of conventional DTH hammer and combine the operating characteristics of RC hammer; internal structure design is optimized to ensure ideal energy transfer and high drilling speed as well as steady sampling.
- Simple internal structure and rigid components ensure long using life and easy maintenance of the hammer.
- Sample tube is integrative designed and can be placed without disassembling of the hammer. With carburizing treatment, the sample tube has good wear resistance.
- RC bit has patented design. One hammer could drill different size of holes just by replacing different size bits, and ensure no contamination of the sample as well.
- In difficult conditions such as loose soil, hard rock formation or plenty of water exists, sampling can be done well.
