What Are the Core Functions of the YG HZ Core Drilling Rig?
- High-efficiency drilling and precise core sampling: Equipped with synthetic diamond thin-walled drill bits and a high-power drive system, drilling speeds can reach 8-12 m/h, core diameters up to Φ200mm, and core integrity ≥95%. It can accurately obtain underground rock samples, reducing sampling errors and adapting to the exploration needs of rock core drilling equipment.
- Easy operation, suitable for beginners: Supports both manual and automatic feed modes. The operation is simple, requiring no professional drilling technicians. Operators can learn to operate it after simple training, reducing labour costs and minimising operational errors.
- Durable and robust, suitable for complex working conditions: High-strength steel structure body, corrosion-resistant and wear-resistant; the column undergoes special surface treatment to withstand complex outdoor environments; core components (drill rod, drill bit, hydraulic system) are all made of high-quality materials, with a low failure rate and a mean time between failures (MTBF) of over 800 hours, reducing equipment maintenance frequency.
- Versatile and Flexible: It can be equipped with different specifications of drill pipes and drill bits to suit various rock formations of different depths and hardnesses, achieving drilling depths of 400-5000mm (with extension rods available). The high-end model supports full hydraulic core drilling rig control, meeting diverse drilling needs.
- Convenient Mobility and Efficient Deployment: The compact and lightweight design allows for transport by ordinary trucks. On-site installation is simple, requiring only 1-2 people to complete installation and commissioning, making it suitable for mountainous areas, mining areas, construction sites, and other locations with poor transportation access.
- Energy-Saving and Environmentally Friendly with Low Operating Costs: Utilising an energy-saving drive system, energy consumption is 20%-30% lower than that of ordinary core drilling equipment, effectively reducing fuel consumption. Replacement of wear parts (drill bits, seals) is convenient, resulting in low maintenance costs and eliminating the need for professional maintenance personnel, further reducing operating costs.
- Safe and reliable with adequate protection: Equipped with emergency stop buttons, overload protection, anti-detachment devices, dust covers, and other safety facilities, which can effectively prevent equipment failures and safety hazards during drilling, ensure the personal safety of operators, and meet international industrial safety standards.

8 Major Application Areas and Use Scenarios of the HZ Core Drilling Rig
- Geological Exploration: In geological surveys and mineral resource exploration, it accurately obtains underground rock strata samples, providing reliable data for resource assessment and engineering design. It is a core drilling equipment in the geological exploration industry, adaptable to various complex rock strata explorations.
- Construction: Before the commencement of building and road/bridge projects, it conducts geological surveys of the construction site to obtain data on rock strata distribution and soil bearing capacity. It can also be used for concrete core drilling to inspect project quality and prevent problems such as foundation settlement and collapse during construction.
- Mining: In coal, metal, and non-metal mining, it is used for preliminary exploration sampling to determine mineral resource distribution and reserves, providing a basis for mining plan development. It can also be used for drilling operations in routine mine maintenance.
- Water Conservancy Projects: In water conservancy projects such as reservoirs, dams, and water diversion projects, it is used for geological exploration and drilling operations to test rock strata stability, providing technical support for water conservancy project design and construction, and is suitable for complex outdoor water conservancy construction environments.
- Road Construction: In the construction of highways, railways, and municipal roads, it is used to explore the geology along the route, determine the bearing capacity of the roadbed, and can also be used for core sampling of pavement concrete to prevent problems such as cracking and settlement after road construction, thus improving the quality of road engineering.
- Stone Quarrying: In quarries and similar settings, it is used for drilling and blasting for stone cutting, suitable for drilling into various brittle and hard materials such as refractory materials, ceramics, and rocks, improving quarrying efficiency.
- Environmental Monitoring: In environmental projects such as soil pollution and groundwater monitoring, it is used for drilling and sampling to test the pollution status of soil and groundwater, providing data support for environmental remediation and accurately obtaining samples of polluted layers.
- Engineering quality testing: In engineering projects such as buildings, highways, airports, docks, and dams, it is used for core drilling of concrete to test the strength and quality of the project. It is an indispensable core drilling equipment in the field of engineering quality testing.

Case Study: HZ Core Drilling Rig Application Case for an Australian Geological Exploration Company
Client Background: A small to medium-sized geological exploration company in Australia, primarily undertaking mineral resource prospecting and geological survey projects, required high-quality core drilling equipment. Previously, they used ordinary rock core drilling equipment, which suffered from low drilling efficiency, poor core sampling accuracy, and inconvenient mobility. After comparing multiple core drilling machine manufacturers, they chose the YG HZ core drilling rig, hoping to improve exploration efficiency and reduce operating costs.
Problems Faced:
- The exploration areas are mostly mountainous with inconvenient transportation, making the transport and installation of ordinary equipment difficult.
- The drilled rock formations are mostly granite, hard and wear-resistant, easily damaging ordinary drill bits and resulting in low drilling efficiency.
- Poor core sampling accuracy and insufficient sample integrity affect the accuracy of exploration data.
- High labour costs, requiring specialised technicians for operation, leading to high maintenance costs.
Solution: YG recommended the standard HZ core drilling rig, which features a compact design for easy transport and installation in mountainous areas; a high-efficiency drive system for improved drilling efficiency, suitable for hard rock formations such as granite; a precision coring device ensuring ≥95% core integrity; simple operation requiring no specialized technicians, with free operator training provided by the manufacturer; and compatibility with a full hydraulic core drilling rig for complex working conditions.
Results: The equipment was easy to transport and install, requiring only 1-2 people for on-site commissioning, significantly reducing labor costs; drilling speed increased to 10m/h, a 50% improvement over previously used ordinary rock core drilling equipment; an exploration project that previously took 10 days could be completed in just 6 days; high core sampling accuracy and complete samples provided reliable data for mineral resource assessment; low failure rate, with over 800 hours of trouble-free operation; 60% reduction in maintenance costs, saving approximately $120,000 in operating costs annually. The client subsequently purchased two more HZ core drilling rigs to expand their business, highly recognising YG’s strength as a core drilling machine manufacturer.
Customer review: “YG’s HZ core drilling rig is efficient, precise, and durable, perfectly solving the pain points of our mountain exploration. As high-quality core drilling equipment, it is easy to operate and move, and can adapt to complex rock formations. The manufacturer offers transparent pricing, and the after-sales service is also very considerate. It is an ideal choice for small and medium-sized geological exploration companies!
