Deep hole exploration drilling rig

Product Introduction

This is a deep-hole exploration drilling rig with a maximum drilling depth of 800 meters, specifically designed for extracting underground rock samples to directly assess mineral resources, geological structures, and engineering geological conditions.

The rig is widely used in general and detailed surveys of solid mineral resources, as well as deep exploration, covering fields such as metallic ores, non-metallic ores, coal, oil, and gas fields. It is also suitable for hydrogeological surveys, engineering geological investigations, and scientific geological coring research. In terms of deep 

geological drilling, this 800-meter rig carries the critical mission of connecting the deep underground with surface scientific research, serving as a key piece of equipment supporting the new round of strategic actions for breakthrough in mineral prospecting.

Product details

1.Power System: This 800m core drilling rig is equipped with a China-IV diesel engine (150-220kW) and an optional electric motor set. Intelligent electronic control adapts to extreme environments such as plateaus and cold regions. An auxiliary emergency hydraulic pump ensures safe withdrawal of the drill string in case of main power failure, fully demonstrating the reliability and energy-saving advantages of the deep-hole exploration rig's power system.

2.Operating System: The rig features an integrated control console where all functions are operated via levers and physical buttons — a screen‑less design that is more adaptable to harsh conditions like dust and humidity at mine sites.

3.Hydraulic System: The full hydraulic system is equipped with dual variable piston pumps for independent oil supply, delivering a rotary torque of ≥1800 N·m with stepless speed regulation, and a pull‑up force of ≥250 kN. Combined with high‑efficiency cooling and fine filtration (oil temperature ≤80°C), it ensures long hydraulic component life and high stability during prolonged continuous drilling.

4.Steel Crawler Tracks: The high‑strength manganese steel welded track frame is integrally heat‑treated. The 400mm wide tracks provide a ground pressure of ≤0.08 MPa. Dual‑speed hydraulic travel motors enable 25° climbing and pivot turning. Spring‑applied brakes automatically lock on slopes, giving the drilling rig outstanding terrainability and relocation safety in complex terrains such as mountains and hills.

5.Drill Rods: Standard composite wireline coring rods (Φ71/89mm) are made of R780 high‑strength steel with trapezoidal threads. A single run recovers a 3.5m long core. Optional casing pipes and hydraulic holders increase rod change efficiency by over 30%. These rods are the core high‑efficiency and durable tooling for hard‑rock deep‑hole coring drilling.

Scope of application

This 800m core drilling rig is widely applicable for general surveys, detailed surveys, and deep exploration of solid mineral resources, covering metallic ores (gold, silver, copper, iron, lead-zinc, etc.), non-metallic ores, as well as coal, oil, and gas fields. It also meets the requirements for hydrogeological surveys, engineering geological investigations, geothermal well exploration, and scientific geological coring research. Leveraging its full hydraulic high torque, efficient wireline coring technology, and steel crawler terrain adaptability, it is particularly suitable for deep coring operations in remote areas with difficult access, such as mountains, hills, and deserts. It is an ideal piece of equipment serving the new round of strategic actions for breakthrough in mineral prospecting and drilling in complex formations.

Quality inspection

In our production workshop, every drilling rig ready for delivery is not a cold industrial product, but a reliable partner carrying craftsmanship and responsibility.

From precision welding of the frame, to the rigorous assembly of the core rotary mechanism, and finally to the full-process commissioning and inspection before leaving the factory, we have embedded "quality" into every single step of the process. The focused eyes of our workers, the repeated calibration of details, and the insistence on every performance indicator — all of this is to ensure that when the rig reaches our customers' hands, it is in its most stable and reliable condition, ready to tackle complex working conditions on site.

There are no shortcuts — only dedication. We firmly believe that a machine that can stand the test is the strongest support for our customers. Every inspection is a promise of quality; every drilling rig that leaves our factory carries our respect for the profession and our sincerity toward our customers, ready to safeguard your projects.
