Frequently Asked Questions
What is the maximum drilling depth of the PDTHR 300?
The PDTHR 300 Water Well Drilling Rig is designed to achieve
a maximum drilling depth of up to 300 metres. DTH drilling
supports depths of up to 1100 feet / 300 metres, while rotary
drilling supports depths of up to 1000 feet / 300 metres.
Does the PDTHR 300 support both DTH and rotary drilling?
Yes. The PDTHR 300 supports both DTH and rotary drilling methods.
DTH drilling is suitable for soft and hard rock formations,
while rotary drilling can be used for unconsolidated and
alluvial formations.
What hole diameters can the PDTHR 300 drill?
For DTH drilling, the PDTHR 300 supports a continuous hole
diameter of 152 mm (6 inches) and an overburden diameter of
up to 254 mm (10 inches). For rotary drilling, it supports a
continuous diameter of 152 mm (6 inches) and reaming up to
304 mm (12 inches).
What applications is the PDTHR 300 suitable for?
The PDTHR 300 is designed for water well and borehole drilling
applications. Its DTH and rotary drilling capabilities allow it
to work across soft rock, hard rock, unconsolidated and alluvial
geological formations.
What type of air compressor is used with the PDTHR 300?
The PDTHR 300 uses an ELGI air compressor rated at approximately
1100 cfm at 300 psi. The compressor is mounted on the same truck
as the drilling rig.
How can I get more information about the PDTHR 300?
You can contact Prime Rigs directly to request detailed technical
specifications, discuss your drilling requirements, and determine
whether the PDTHR 300 Water Well Drilling Rig is suitable for
your project.
