Reverse Circulation drilling, or RC drilling, uses rods with inner and outer tubes, the drill cuttings are returned to surface inside the rods. The drilling mechanism is a pneumatic reciprocating piston known as a hammer driving a tungsten-steel drill bit.

Jul 24, 2017 · RC, or reverse circulation, drilling is a tried and true drilling method in certain circumstances. Drillers usually use it on large-diameter holes because it is faster and easier to clean the hole. The fluid and cuttings flow up the drill pipe and down the annulus.

Reverse circulation drilling, or RC drilling, is a form of percussion drilling that uses compressed air to flush material cuttings out of the drill hole in a safe and efficient manner.

An RC-equipped drill rig can quickly be converted to production drilling. Our rigs support inclined drilling which makes it easier to find the boundaries of the ore body. Reverse Circulation (RC) is a fairly simple sample method used for in-pit grade control.

Jul 27, 2012 · RC drilling is a technique used in the majority of stages of mine development. As it is cheaper than diamond core drilling, it is often used in first stage exploration mining to delineate a potentially extractable ore body.

By continuously investing in efficient and safe reverse circulation coring rigs and equipment, you can count on Boart Longyear for industry-leading core recovery rates and up-time. In-house engineers upgrade and retro-fit reverse circulation drill.

Jul 25, 2013 · Reverse circulation or RC drilling is a fast and inexpensive method of drilling, particularly compared to diamond drilling. A hundred metres of more of drilling is possible per day. RC is a commonly used drilling method in the mineral exploration industry.

Reverse Circulation drilling, or RC drilling, is one of the most popular methods of mineral exploration drilling. This guide will give you an introduction to RC drilling. We will be covering: How does RC Drilling Work? RC drilling uses rods with inner and outer tubes, the drill cuttings are returned to the surface inside the rods.

Sep 22, 2024 · RC drilling is a technique used in the majority of stages of mine development. As it is cheaper than diamond core drilling, it is often used in first stage exploration mining to delineate a potentially extractable ore body.

Dec 4, 2024 · Reverse Circulation drilling, or RC drilling, is a method of drilling which uses dual wall drill rods that consist of an outer drill rod with an inner tube. These hollow inner tubes allow the drill cuttings to be transported back to the surface in a continuous, steady flow.
