Октябрь 22, 2026

Project Overview

Location: Африка
Application: Mineral exploration and geological investigation
Оборудование: Гидравлическая буровая установка для отборочного бурения глубиной 600 м
Key Requirements: Deep drilling, reliable core recovery, and field mobility

1. Project Background: Deep Drilling for Mineral Exploration

Mineral exploration projects in Africa often require drilling equipment that can operate under demanding geological and field conditions. For this project, the customer needed a reliable drilling solution capable of reaching approximately 600 meters to investigate underground rock formations and collect core samples for geological analysis.

The collected samples would help the exploration team evaluate rock structures, identify potential mineral-bearing zones, and support decisions about further exploration. To meet these objectives, the drilling rig needed sufficient power, stable rotary performance, and a suitable wireline coring system.

Field mobility was another important consideration. Exploration teams may need to move equipment between drilling locations with uneven terrain and limited maintenance facilities. The selected machine therefore needed to balance drilling capacity, transportability, and practical operation.

Based on the project’s target depth and core sampling requirements, RUIXIN recommended a Гидравлическая буровая установка для отборки керна длиной 600 м equipped with a Yuchai turbocharged diesel engine, hydraulic winch, and BW9-3 mud pump. The configuration was intended to support deep geological drilling while providing the flexibility required for field exploration.

2. Key Challenges in the Project

The customer’s requirements involved several important considerations:

Target drilling depth: The equipment needed to reach approximately 600 meters using the specified drilling rod configuration.
Representative core samples: Stable drilling parameters and suitable wireline coring tools were important for recovering samples for geological evaluation.
Variable rock formations: Drilling pressure, rotation speed, and drilling tools needed to be adjusted according to actual formation conditions.
Field mobility: The rig needed to move between drilling locations and operate on uneven ground.
Maintenance practicality: The power, hydraulic, hoisting, and mud circulation systems needed to be accessible for inspection and routine servicing.

These requirements made equipment matching more important than simply selecting a rig with a larger nominal drilling depth.

3. Equipment Selection: Why a 600m Core Drilling Rig?

RUIXIN selected a 600m Hydraulic Core Drilling Rig based on the target drilling depth, required hole diameter, and field operating conditions.

A rig’s maximum drilling depth depends on the drilling rod size and the configuration used. For this project, the selected model provides a maximum drilling depth of 600 meters with NTW rods, making it suitable for the specified exploration target.

The rig also supports a recommended hole diameter range of φ60–110 mm and a drilling angle of 45°–90°. This allows the exploration team to configure drilling operations according to the planned borehole and geological investigation requirements.

How the Configuration Supports the Project

1. Engine power and rotary performance

The 91 kW diesel engine provides power for the drilling and hydraulic systems. With a maximum torque of 1,600 N·m, the rig is configured to provide rotary force for core drilling under different formation conditions. Operators should adjust rotation speed and drilling pressure according to rock hardness, bit condition, and drilling response.

2. Hydraulic control and core retrieval

The hydraulic system supports the operation of the power head and associated drilling functions. The hydraulic winch and wireline coring arrangement help retrieve core samples without requiring the entire drill string to be withdrawn for every core retrieval cycle. This can reduce interruptions associated with conventional core recovery methods, depending on the drilling conditions and equipment setup.

3. Mud circulation

The BW9-3 mud pump supplies drilling fluid circulation to help remove cuttings and support borehole stability. Appropriate fluid selection and circulation settings remain important, particularly when drilling through fractured or unstable formations.

4. Crawler mobility

The steel crawler chassis helps the rig travel between drilling locations on uneven ground. Its compact, crawler-mounted design is useful for field projects where equipment must be repositioned as exploration progresses. Actual mobility depends on terrain, ground bearing conditions, gradients, and site access.

5. Balanced equipment selection

Choosing a 600m model allows the equipment capacity to match the stated drilling target without automatically moving to a larger rig. The final selection should also account for the geological formation, required core diameter, drilling method, available support equipment, and expected working schedule.

4. Factory Inspection and Overseas Delivery

Before shipment, RUIXIN carried out factory inspection and testing of the main equipment systems.

The preparation process included the following stages:

Stage 1 — Equipment configuration

The drilling rig configuration and supporting accessories were prepared according to the project requirements.

Stage 2 — Factory inspection

The engine, hydraulic system, power head, winch, mud pump, and crawler system were checked before delivery.

Stage 3 — Shipment preparation

The equipment and matching drilling accessories were prepared for overseas transportation, with protective measures selected to suit the components and shipping arrangements.

Stage 4 — Delivery to the project

The rig and supporting equipment were dispatched for the overseas geological exploration project. After arrival, site preparation, equipment checks, and commissioning should be completed before drilling begins.

5. Application Value for Geological Exploration

The 600m hydraulic core drilling rig provides a configuration suited to the project’s stated drilling depth and geological sampling requirements.

Its key application advantages include:

Support for deep exploration: A maximum NTW drilling depth of 600 meters provides the required nominal capacity for the target borehole.
Wireline core retrieval: The coring arrangement can help reduce time spent retrieving samples compared with methods that require full drill-string withdrawal for each recovery cycle.
Adaptable drilling operation: The adjustable drilling angle and hydraulic controls support different borehole arrangements and operating conditions.
Field mobility: The crawler chassis assists movement between drilling locations.
Integrated drilling systems: The engine, hydraulic system, winch, and mud pump work together to support the core drilling process.

Actual drilling speed, core recovery rate, daily output, and operating costs depend on geological conditions, drilling tools, operator practices, maintenance, and site logistics. These results should be evaluated through field operating records rather than estimated from equipment specifications alone.

6. Project Takeaways

This African mineral exploration project highlights the importance of matching a core drilling rig to the actual requirements of geological investigation.

The 600m Hydraulic Core Drilling Rig combines 91 kW engine power, 1,600 N·m maximum torque, wireline core retrieval capability, and crawler mobility in a configuration designed for medium-depth mineral exploration.

For exploration contractors and mining companies, selecting the right equipment involves more than checking maximum drilling depth. Hole diameter, rock formation, core recovery requirements, drilling angle, transportation conditions, and maintenance resources all affect the suitability of the final configuration.

By evaluating these factors before ordering, project teams can make more informed equipment decisions and prepare a drilling solution that fits their operational requirements.
