MINERAL EXPLORATION
TECHNIQUE

2. Diamonds are very hard substances that
come in different types. They can be quality
gem stones used for making jewellery and
industrial diamonds for making the drill bits
utilized for drilling diamonds. Such bits are
usually made to penetrate a certain kind of
material and possibly do not fit any other
kind of drilling.

4. Parts of a Diamond Drilling System
Diamond drilling is a technique used in the
mining industry to explore minerals. This is
used in determining the potential of a site to
be mined. A system for drilling diamonds is
quite complex; however, diamond drilling
contractors simply this by concentrating on
three parts:

5. • Rotary Drill- The machine’s bulk that give
the power.
• Drill Rod-The barrel that is composed of a
core during the completion of the drilling.
• Diamond Bit- The circular tool with an
open middle area. It is responsible for
clearing ground entry.

6. How the Core Works
The core is the part of the Earth that is
eliminated for inspection. This often
determines a possible mining site’s fate. This
is available in four standard sizes. Big core
samples require more power, bigger drill
bits and bigger drill rods. Thus, this leads to
higher costs.

8. In extracting the core, the three system parts
must be considered. The drill is extended into
the drill rod that has a diamond drill bit on its
end. Rotary action is used by the drill for
providing power so that the drill will be forced
into the ground. When the drill has penetrated
into the Earth with the drill already slid in, the
core is pushed through the drill bit’s middle
hole. Then the core continues to slide into a drill
rod. A wire mechanism takes place within each
drill rod for containing and recovering the core
sample inside. With this catching mechanism, it
will be easier to bring the core to surface.
