There are numerous type of drilling methods used in the construction industry. Each of the drilling method has its own characteristic structure applicable to certain type of surfaces. This piece by We-Bore-It, a leading US based directional drilling and boring contractor, highlights the popular drilling methods used by drilling contractors all around the world.

1. How Drilling Methods Differ
According to Different Surfaces

2. Drilling is a process of creating the holes in the
surface of the land.
These holes are made with drilling rigs.
A drilling rig is a huge equipment and are powerful
enough to dig the water, gas and oil wells.

3. Drilling Rig

4. ●Drilling rigs have to sample the surface properties before
starting its drilling projects, such as the mineral deposits,
soil properties, test rock and underground water
properties.
●These rigs are also used to install the pipes and other
material for the tunnels, holes and wells.
●There are different types of drilling rigs having their own
unique properties and functions, each of the drilling rig
work differently for the different types of lands and
surfaces.
Drilling rigs and Methods

5. 1. Auger Drilling

6. This type of drilling is mostly done on the harder
grounds. It is also used to dig the mines. This is not a
suitable type for the soft or weak rocks. These are an
affordable and time saving type of drilling.
In this drilling, the helical screw works which enters
the ground while rotating. Then the land is lifted up
by the blade of the screw.

7. 2. Air Core Drilling

8. This method is used for the unconsolidated and regolith
ground.
It is difficult to penetrate the fresh and soft rock through
this method.
This drill has the three blade system and made of steel and
tungsten and it cuts through the suitable ground.
The land cut by the drill is moved by the compressed air in
the injection.
By this the cuttings blow out to the surface by the tube and
the drill rod.
This meter can reach up to 300 meters deep.
This method is expensive and takes a lot of time.

9. 3. RAB (Percussion Rotary Air
Blast Drilling)

10. RAB drilling is mostly used in the exploration
of the minerals, water boring, and hole drilling
in mines.
It is also used in the field of engineering.
Through this method the land cut is blown out
of the surface and collected.

11. 4. Diamond Core Drilling

12. Diamond core drilling method is a little slow as
it is used in drilling mostly the hard surfaces.
These drills are also known as the multiple
combination rigs as they work with the reverse
circulation as well as the diamond drilling role.

13. 5. Sonic Vibratory Drilling

14. A Sonic vibratory drilling rig works by sending
out the high frequency from the string to the
drill bit.
The frequency is controlled by the worker
according to the type of the land.
This frequency rate is between 50-120 hertz.

15. We-Bore-It has been providing directional boring & trenching services to
the Cable, Telecommunications and Wireless industry since 1990. The
company was founded with the idea of uniting multiple contracting
companies under one umbrella company. After years in the industry, and
valuable feedback from customers and partners it became clear that they
wanted us to expand our operations from that of local to that of a regional
or even nationwide operator. Our goal is to offer our residential and
commercial customers a service that focuses on all their underground
construction needs.
