Frequently Asked Questions
01
What drilling depth and hole diameter ranges do we reverse circulation
(RC) drilling rigs support?
The series offers flexible configurations covering maximum drilling depths from 400m to
1,200m and hole diameters from 105mm to 800mm.
02
What drilling methods and geological strata is the rig designed for?
It supports compressed air reverse circulation DTH hammer drilling and mud drilling,
making it suitable for both loose strata and solid bedrock in mineral exploration and
deep sampling.
03
How does the system manage sample purity, dust control, and clay blockages?
Samples are collected via a cyclone separator to avoid contamination, dust is captured
by an integrated collector, and an internal hole-cleaning device clears clay blockages
promptly.
04
What mechanical features extend drill pipe life and increase drilling stability?
A ground-contact compensation cylinder enhances mast rigidity, while a compensation-type
slide plate absorbs shock loads to protect drill pipe threads.
05
What key brands and components power the engine and hydraulic systems?
The rig uses Cummins or Yuchai engines, paired with premium hydraulic components such as
Permco pumps and valves from Sun Hydraulics, Hengli SHLIXIN, Taiwan Yolly, and Shanghai
Qiangtian.
