HDH (Horizontal Drain Hole) drilling is a specialized technique designed to reduce pressure on slope walls. Commonly used in open-pit mining dewatering, both horizontal and vertical drilling processes are employed to create inclined pit drains. Our custom Mirage drills, operated by highly trained personnel, provide comprehensive solutions for horizontal pit drains and wall depressurization.

We offer various drilling options, including cased and perforated holes, uncased holes, PVC lining, or a combination of these techniques, to significantly enhance ground stability.
