Geological exploration work often requires operation in complex terrain and remote areas, where traditional heavy-duty drilling rigs are often unable to reach the work site. In such situations, a flexible and efficient HZ series core drilling rig becomes particularly important.
The HZ series small core drilling rig is a hydraulically driven, small-diameter core sampling exploration device. It is also commonly referred to in the industry as a portable core drilling rig, small diamond core drilling rig, or shallow-hole exploration drilling rig. As a member of the professional hydraulic core drilling rig family, the HZ series focuses on the 130-200 meter shallow-hole drilling market and is known for its flexibility and portability.
The HZ series small core drilling rig is a lightweight, fully hydraulic core exploration drilling rig specifically designed for shallow and medium-depth geological exploration. With its compact structure, easy assembly and disassembly, and reliable drilling performance, it is an ideal choice for geological surveys, engineering exploration, and mineral investigation. Whether in rugged mountains, dense forests, or remote mining areas, the HZ series drilling rig can flexibly handle the terrain, helping exploration teams quickly complete drilling tasks.
As a professional drilling equipment manufacturer, YG’s HZ series core drilling rigs have been successfully exported to numerous hot exploration markets in Southeast Asia, Africa, and South America, winning the trust of global customers with their excellent cost performance and reliable quality.

What Are the Application Scenarios for the HZ Series Small Core Drilling Rig?
Typical Application Areas:
- Geological Survey and Detailed Investigation: Regional geological surveys, mineral exploration, and shallow hole drilling for intensified exploration.
- Engineering Geological Investigation: Construction site investigation, bridge foundation investigation, tunnel entrance investigation.
- Geological Hazard Investigation: Landslide hazard investigation, collapse investigation, ground settlement monitoring boreholes.
- Railway and Highway Investigation: Engineering geological investigation of railway lines, slope stability investigation.
- Water Conservancy Engineering Investigation: Reservoir dam site investigation, embankment foundation investigation, canal route selection investigation.
- Mine Slope Investigation: Open-pit mine slope stability investigation, tailings dam investigation.
- Environmental Geological Investigation: Contaminated site investigation, soil sampling, hydrogeological investigation.
- Scientific Research and Teaching Practice: University geological internships, field sampling.
Suitable Target Market:
The HZ series core drilling rig has broad demand in the global exploration market. The tropical rainforests and mountainous terrain of Southeast Asia (Indonesia, Philippines, Laos, Myanmar) are complex, making it difficult for large equipment to access; the grasslands and mining areas of Africa (Kenya, Tanzania, Zambia) have limited road conditions; and the Andes Mountains of South America (Peru, Ecuador, Colombia) are also ideal markets for the HZ series drilling rigs. These regions have a strong demand for flexible, lightweight, and cost-effective shallow-hole exploration equipment.

What Are the Key Issues to Consider When Purchasing an HZ Series Small Core Drilling Rig?
- How to choose the drilling depth?
The HZ series has three depth specifications. The selection should be based on the maximum designed hole depth of the project:
- 130-meter class (HZ-130Y): Suitable for shallow geological surveys, soil sampling, and environmental monitoring.
- 180-meter class (HZ-180Y): Suitable for medium-depth engineering exploration and mineral prospecting.
- 200-meter class (HZ-200Y): Suitable for deeper engineering exploration and detailed mine surveys.
It is recommended to choose a model 20%-30% deeper than the designed hole depth as a safety margin. If the project requires drilling at different depths, consider choosing the deepest model for maximum flexibility.
- How to choose the power source?
The HZ series drilling rigs can be driven by either a diesel engine or an electric motor:
- Diesel engine drive: Suitable for exploration sites without electricity, offering high mobility but with higher noise and emissions.
- Electric motor drive: Suitable for sites with a stable power supply or areas with high environmental requirements, offering lower noise and operating costs.
Choose the appropriate power source based on the power conditions of the project site. For sites requiring versatility, a dual-power configuration can be selected.
- How to match the mud system?
The HZ series is equipped with BW90 or BW160 mud pumps. When purchasing, consider:
- BW90 pump: Smaller displacement, suitable for shallower holes or formations with low permeability.
- BW160 pump: Larger displacement, suitable for deeper holes or formations requiring strong cuttings carrying capacity.
If the project has complex geological formations, additional mud mixing and purification equipment may be required. For construction in arid regions, the feasibility of air drilling can also be considered.
- How to assess transportation conditions?
- Assess the project’s transportation conditions before purchasing: Is the road at the work site passable for transport vehicles?
- What are the maximum weight and size limits for a single transported unit?
- How many relocations are required? What is the relocation frequency?
The HZ series drilling rig can be transported in parts; the heaviest module weighs approximately 500kg and can be transported by regular trucks or pickup trucks. However, for extreme terrain, further disassembly or a lighter model may need to be considered.
- How long is the operator training period?
As a fully hydraulic core exploration drilling rig, the HZ series is relatively easy to operate. After systematic training:
- Operators with drilling experience can operate proficiently in 3-5 days.
- New operators can work independently in 7-10 days.
When purchasing, you can request on-site training services from the manufacturer to ensure that operators master the correct usage and maintenance methods. Standardized training and operating habits can significantly extend the equipment’s lifespan.
- How are after-sales service and spare parts supply guaranteed?
When purchasing, you should examine the supplier’s after-sales service capabilities:
- Do they provide equipment commissioning and operation training?
- What is the spare parts supply cycle? Do they support international shipping?
- Is there a technical support hotline or online service?
It is recommended to partner with a fully hydraulic core drilling rig manufacturer that has extensive export experience, such as YG Machinery, which can ensure timely supply of spare parts and reliable technical support.
