Case Study: Application of a Small Core Drilling Rig in Geological Survey

1. Project Background
In 2025, a geological exploration project was launched in Guizhou Province, China, aiming to investigate subsurface rock structures for potential mineral resources. The working area was located in a mountainous region with narrow access roads and rugged terrain, making it unsuitable for large drilling equipment. To address these challenges, the Jinghe XY-100 Small Core Drilling Rig was selected for the job due to its compact design, portability, and high drilling efficiency.

2. Equipment Overview
The Jinghe XY-1 Small Core Drilling Rig is a lightweight, portable exploration rig designed for shallow to medium-depth drilling (up to 200 meters). It features:

• Compact structure and modular design, allowing manual transport in remote areas.
• Gasoline engine power with low fuel consumption.
• High-speed rotary system, capable of obtaining high-quality core samples in various geological formations.
• Easy assembly and disassembly, reducing setup time significantly.

3. Field Application
The drilling team used the Jinghe XY-1 rig for six boreholes, with an average depth of 120 meters each. Due to the terrain’s steep slopes, the rig components were manually carried to each drilling site. The modular system allowed for rapid installation—each setup took less than two hours.
The drilling process encountered mixed formations of clay, sandstone, and limestone. The rig’s adjustable drilling speed and stable torque output ensured smooth operation and high recovery rates of core samples.

4. Results and Performance

Core recovery rate: 92% on average

Drilling speed: 12 meters/hour in sandstone layers

Fuel consumption: 0.9 liters/hour

Operational stability: No major equipment failures during the 15-day operation

The results met the geological team’s requirements for core integrity and precision, providing reliable data for further analysis. The small core drilling rig demonstrated its value in field exploration with limited space and challenging terrain.

5. Conclusion
The Jinghe XY-1 Small Core Drilling Rig proved to be an effective and economical choice for geological exploration in remote and mountainous areas. Its portability, ease of use, and high efficiency make it ideal for preliminary surveys, mineral exploration, and academic research where mobility and sample accuracy are essential.
