Case Study 1: Metal Exploration Project for a Mining Company in Luzon, Philippines

Client Background: A medium-sized mining company in Luzon, Philippines, specializes in gold and copper exploration and mining. The project is located in a mountainous area with steep terrain and complex strata, including hard granite, fractured zones, and alternating layers of hard and soft rock. Previously, they used outdated mechanical drilling rigs, which resulted in low drilling efficiency, severe core fragmentation, frequent stuck drill bits, and difficulties in relocation, significantly delaying exploration progress. After comparing various options, the company purchased a YG fully hydraulic core exploration drilling rig in 2024, along with standard NQ core drilling rig tools, for deep resource exploration in the mining area.

Construction Challenges:

• Rugged terrain made equipment relocation difficult; traditional drilling rigs required multiple operators and took over two days.
• Complex and variable strata made drilling in hard rock difficult; fractured zones were prone to borehole collapse, resulting in a core recovery rate of less than 60%.
• High temperatures and heavy rainfall made the equipment susceptible to moisture damage and the hydraulic system prone to failure, affecting continuous operation.
• With a tight schedule, the project required the completion of 12 boreholes and a total drilling depth of 4500 meters within 3 months.

Solution:

• The YG technical team, based on project requirements, customized a construction solution for the client: A tracked, fully hydraulic core drilling rig was selected, equipped with wireless remote control, allowing for single-person operation and relocation, completing the move and positioning within a single day.
• A fully hydraulic core drilling rig load-sensitive system was employed, automatically adjusting torque and speed according to formation hardness, increasing force in hard rock and reducing speed in soft rock to protect core integrity.
• Using the NQ core drilling rig’s dedicated wireline coring tool, core extraction could be performed without lifting the drill bit, reducing the number of drill lifts and improving efficiency.
• The equipment was equipped with an independent temperature control and cooling system and a moisture-proof sealing device, adapting to the high temperature and humidity environment of the Philippines, ensuring continuous and trouble-free operation.
• On-site operation training and full technical support were provided, with engineers dispatched to the site for guidance and rapid resolution of construction problems.

Application Results:

• Significantly Improved Efficiency: The highest single-shift drilling footage reached 85 meters, with an average drilling footage 60% higher than traditional drilling rigs, completing all exploration tasks 25 days ahead of schedule.
• Excellent Core Sampling Quality: Core recovery rate remained consistently between 92% and 96%, obtaining complete mineral layer samples and providing accurate data for resource reserve assessment.
• Strong Adaptability: The tracked chassis easily handles steep terrain, reducing equipment transfer time from 2 days to 4 hours; the fully sealed design is impervious to rain and moisture, allowing for an average of 28 operating days per month.
• Significantly Reduced Costs: Reduced manpower by 3 people, failure rate decreased by 70%, maintenance costs decreased by 65%, and overall construction costs decreased by 40%.

• Deep hole drilling was challenging; the outdated equipment lacked sufficient torque and had slow progress, requiring more than 7 days to drill a single 300-meter hole.
• The projects were geographically dispersed and had tight schedules, necessitating rapid equipment relocation and continuous operation to shorten the overall cycle.
• The coastal salt spray environment makes equipment susceptible to corrosion, requiring high durability and maintainability.

Solution:

• A high-torque, fully hydraulic core exploration drilling rig is selected, with a power head torque of 8000 N·m, providing ample power for deep hole drilling.
• Equipped with a hydraulic automatic centering and verticality monitoring system, it accurately controls the borehole inclination in soft soil layers, with a verticality error of ≤0.5%.
• The modular design allows for easy disassembly and, with a dedicated trailer, cross-project relocation takes only one day.
• Key components are made of corrosion-resistant materials, and the hydraulic system is equipped with salt spray-proof seals, simplifying daily maintenance and adapting to the coastal environment.
• Simultaneous technical support is provided for multiple projects, and a remote fault diagnosis system is established for rapid response to construction issues.

Application Results:

• Highly efficient and stable deep hole drilling: The construction cycle for 300-meter deep holes is shortened to 3 days, with sufficient torque, smooth drilling, and no hole collapse or stuck drill.
