Fully Hydraulic Rope Core Drilling Rig: A New Benchmark for Efficient Exploration, Reshaping the Future of Geological Drilling

Fully hydraulic rope core drilling rig: a new benchmark for efficient exploration, reshaping the future of geological drilling

In today's rapidly developing geological exploration technology, the fully hydraulic rope core drilling rig is becoming a focal device in the global mineral, hydrological, and engineering exploration fields with its revolutionary and efficient design. It perfectly combines the powerful power of the fully hydraulic drive system with the efficient and convenient rope coring technology, significantly improving operational efficiency and data quality through the core method of "no drilling and coring", and is redefining the standards of modern drilling.

Core technology of fully hydraulic core drilling rig: How to achieve efficient core extraction without lifting the drill?

Rope coring technology: The equipment adopts an innovative double-layer drill pipe design. The inner tube accommodates the rock core, while the outer tube maintains the stability of the borehole wall. When extracting the core, it is only necessary to quickly lift the inner tube assembly filled with the core from the inside of the drill rod to the ground through a steel wire rope, without repeatedly pulling up and down the entire set of drill rods that are hundreds or thousands of kilometers long. This design reduces auxiliary time by over 70%, which is the key to efficiency leap.

Intelligent hydraulic drive: equipped with an advanced load sensitive hydraulic system, it can provide smooth and continuously variable power output for the power head, automatically adapting to complex working conditions from soft soil to extremely hard rock layers. Key mechanisms such as bullet card positioning and core blockage alarm system are integrated here, ensuring high reliability and low failure rate of operation.

Performance parameters of exploration drilling rig

To meet the different needs from shallow exploration to deep exploration, modern fully hydraulic rope core drilling rigs have a wide range of performance coverage:

Drilling depth: covering a range of 200 to 2000 meters.

2. Drilling performance: Power head speed 0-1400 revolutions per minute. For hard rock layers, higher rotational speeds (400-1000 revolutions per minute) can be used, while in fractured areas, for safety reasons, it is best to maintain the rotational speed between 400-600 revolutions per minute.

3. Flexible operation: The drilling angle of the core drilling rig is 45 ° to 90 °, which is suitable for inclined and vertical holes.

4. Mobility and efficiency: The core drilling rig has the ability to walk on its own, with a maximum speed of about 3km/h and convenient transfer; The lifting speed of the winch can reach up to 110m/min, further improving the cycle speed of the operation.

Advantages of using rope core drilling rig:

1. Significant cost reduction and efficiency improvement: significantly reducing the number of drilling operations, reducing labor intensity by about 50%, and overall operating costs are expected to decrease by 20%.

2. Security upgrade: Wireless remote control operation can be optionally selected to keep the operator away from potential hazards at the wellhead.

3. Excellent data quality: With high stability, the verticality error of the borehole can be controlled within 0.5%, and the average integrity of the obtained rock core is as high as 98.6%, providing extremely reliable samples for geological analysis.

Application scope of core drilling rig:

1. Mineral resource exploration: Accurate assessment of ore body structure and mineral distribution.

2. Hydrogeological survey: Groundwater monitoring well drilling and aquifer sampling can be carried out.

3. Engineering Geology and Survey: Provide key geotechnical parameters for the construction of buildings, bridges, and tunnels.

4. Environmental investigation: Meet the needs of deep geological research and environmental sample collection.
