Introducing the Hydraulic Underground Core Drilling Rig
The hydraulic underground rock core drilling rig is a high-performance and multi-functional tool built for on-site drilling operations in coal, geological, metallurgical and engineering industries. Nonetheless, this rig can drill to a depth ranging from 200 to 350 meters and is therefore perfect for various under ground drilling projects.
Key Specifications:
-
Drilling Depth: 200-350m
-
Engine Power: 45kW
-
Rotary Torque: 895N.m
Overview:
The drill rig is mainly designed to drill dewatering gas wells in mines, galleries, coal mines, water injection wells, and large-diameter horizontal drilling. Its versatility allows it to apply to the large-diameter roller drilling, heavy tungsten-carbide drilling, and the percussive-rotary drilling methods.
The hydraulic system of the rig has enabled it to provide precise control and also efficient drilling operations underground since it was designed. The strong structure of the device guarantees reliability and durability under extreme conditions, and the powerful engine provides the needful torque to penetrate through multiple strata.
Whatever your role is – carrying out exploration drilling, sampling cores, or undertaking geotechnical investigations – the hydraulic underground core drilling rig performs excellently and reliably. Enjoy the advantages of the innovative drilling rig, which has been developed to implement the underground drilling tasks promptly.
