reverse circulation drilling

SRC545 Carburized Steel Reverse Circulation RC Hammer For Exploration



Product Introduce:

RC drilling uses a drill bit that features round, protruding tungsten-carbide buttons, to cut through hard rock and earth. The drill rods themselves are hollow and feature an inner tube with an outer barrel (similar to air core drilling).

A pneumatic reciprocating piston (also known as a downhole hammer) delivers rapid impacts to the drill stem, transferring this energy through the drill bit. This extra concussive force hammers the bit into the rock, pulverising it, while a rotational device ensures that the drill bit hits new sections of rock with each impact.

Inside the drill bit, a dual-walled drill pipe is used to achieve circulation, with compressed air getting injected between the tubes to flush the cuttings from the hole and up through the inner tube. The cuttings travel back up the tube to the surface, into a cyclone, where they go over a splitter that delivers the samples into a sample bag.

The exploration team then collects the samples, align them to the hole depth, and layout for their client to log. From here the sample is transported to their lab for assay.

RC drilling typically produces dry cuttings, as their compressors also pump air ahead of the drill bit, drying the rock in the process.

While the process itself is typically dry, water can be injected when collaring a new hole as a way to reduce dust and assist in lifting cuttings to the surface. When water is injected, an additive gets mixed into the water, known as Super Foam. This makes the cuttings bind to each other, increasing sample recovery.

Product Adavantages:

      1.Achieves greater penetration in hard rock than air core drilling, thanks to the percussive force and the                  strength of the drill bit.

2.Provides greater sample accuracy, and cuttings are easy to catalogue. The collected samples have an exact location and depth where they were acquired, making it easier to more precisely locate mineral deposits.

3.Ideal for harsh environments. RC drilling uses approximately 40% less water than diamond drilling, making it a better option for remote area drilling.

4.Reduced risk of cross-contamination. As the cuttings travel through the drill bit’s inner tube and aren’t introduced to other areas of the drill hole, the samples remain uncontaminated.

5.Faster and more efficient, reducing costs and providing greater returns. RC drilling achieves higher production rates and can achieve up to 200/300 metres per day. This means that results can be delivered to clients faster, as the drilling itself takes less time. The speed and efficiency involved also reduces manhours on the drill rig, meaning savings on overall staff hours. Thanks to the power and efficiency of the equipment, RC drilling is more resilient in harsh environments, which makes it a cheaper option overall. In fact, RC drilling has been shown to reduce costs by 25-40%.

1.RC drilling is a technique used in the majority of stages of mine development.

2.RC drilling is commonly employed in open-cut mines and used for pit grade control and in delivering useful insight for mine planning and blasting. It has an optimal depth of between 300-500 metres.

3.RC grade control is extremely effective in defining boundaries between ore bodies and waste rock

4.RC drilling is ideal for exploration, as it delivers contaminant-free samples, which are collected at the drill itself and can be sent immediately for assessment. It also reduces handling time, which in turn can serve to reduce overall program costs.
