Ahundred metres or more of drilling is possible a day. RC is acommonly 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 ahigh performance air compressor at the surface. An air-driven hammer at the end of the drill stem pounds atungsten-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 acyclone splitter that slows the air flow down and divides the sample into small and large samples.Features:1. Manufactured using premium hardened metals for long life;2. Maximum material recovery, up to 98%;3. No cross contamination of samples;4. Handles injection of water, foam, oil, and polymers without performance loss;5. Delivers maximum drilling under water.
