Parameter Interpretation
The four models cover most mineral exploration and geological drilling requirements.
- YGX-400 is ideal for shallow exploration, engineering surveys, and geological investigation up to 500m.
- YGX-600 offers greater lifting force and deeper drilling, making it suitable for medium-depth mineral exploration.
- YGX-800 balances drilling depth, hydraulic performance, and operating cost. It is one of the most popular models for professional mining contractors.
- YGX-1000 is designed for deep exploration projects exceeding 1000 meters. Its Cummins engine, 30T lifting force, and 300L/min hydraulic flow provide stable performance in demanding drilling conditions.
The combination of powerful hydraulic feeding, high lifting capacity, and dual cooling systems allows operators to maintain continuous drilling while improving core recovery quality.

6 Reasons Contractors Choose Core Drilling Equipment for Difficult Projects
Modern exploration projects demand much more than drilling depth. Contractors need reliable hydraulic performance, accurate drilling control, and equipment capable of working in different geological formations.
A fully hydraulic drilling system offers several advantages:
- High drilling accuracy
- Stable hydraulic control
- Deep drilling capability
- Strong lifting performance
- Reduced labor intensity
- Excellent mobility
- Lower maintenance costs
- Better core recovery quality
Unlike conventional mechanical rigs, hydraulic systems provide smoother feeding and rotation. Operators maintain better control throughout the drilling process.
High lifting force also improves drill rod handling efficiency. This reduces non-drilling time and increases daily productivity.
YG Machinery designs every hydraulic core rig for continuous operation under demanding mining and exploration conditions. Strong structural components improve reliability while reducing unexpected downtime.

5 Core Drilling Machines for Mining Applications That Increase Productivity
Professional core drilling machines for mining projects involve many different drilling objectives. Selecting suitable equipment allows contractors to expand their business while improving equipment utilization.
Typical applications include:
Mineral Exploration
Geologists collect continuous core samples for mineral evaluation and reserve estimation.
Geological Investigation
Engineering companies analyze underground formations before large construction projects begin.
Hydropower Projects
Core drilling verifies rock conditions for dams, tunnels, and underground facilities.
Railway And Highway Construction
Engineers investigate foundation stability before bridge and tunnel construction.
Scientific Research
Universities and research organizations collect deep geological samples for environmental and geological studies.
Besides mining exploration, these hydraulic rigs can also support geothermal investigation, infrastructure projects, and deep engineering surveys. For contractors handling multiple drilling services, one machine can serve various industries throughout the year.
7 Engineering Advantages That Make Deep Drilling Easier
Modern hydraulic drilling rigs combine several systems to improve both drilling quality and operational efficiency.
Important advantages include:
Fully Hydraulic Power System
Stable hydraulic transmission improves drilling precision while reducing operator workload.
Powerful Lifting Capacity
Up to 30 tons lifting force simplifies drill rod handling during deep drilling operations.
Adjustable Drilling Angle
Different models support drilling angles from 0–90° or 45–90°, allowing flexible operation under various project conditions.
Dual Cooling System
Air cooling and water cooling work together to maintain stable hydraulic temperatures during continuous drilling.
Heavy-Duty Crawler Structure
Crawler mobility allows efficient movement across rough terrain without additional transportation equipment.
High Hydraulic Flow
Large-capacity hydraulic pumps provide consistent power for deep drilling applications.
Reliable Engine Options
Yuchai and Cummins engines deliver stable output while maintaining excellent fuel efficiency under heavy workloads.
How the Hydraulic System Keeps Every Meter of Drilling Stable
Deep exploration requires precise coordination between rotation, feeding, lifting, and mud circulation. The YGX series combines these functions into one fully hydraulic system to improve drilling efficiency and core quality.
The drilling process follows these steps:
Step 1 – Machine Positioning
The crawler chassis moves the rig to the drilling location. Hydraulic supports stabilize the machine before drilling begins.
Step 2 – Drill Rod Rotation
The rotary head delivers continuous torque to the drill rods. Hydraulic control keeps rotation smooth under different geological conditions.
Step 3 – Feeding System
Hydraulic cylinders push the drill string downward at a controlled speed. Operators can adjust the feed force according to rock hardness.
Step 4 – Diamond Core Cutting
The diamond drill bit cuts through the formation while producing a continuous cylindrical core sample.
Step 5 – Mud Circulation
The hydraulic mud pump circulates drilling fluid through the drill rods. The fluid cools the bit, removes cuttings, and stabilizes the borehole.
Step 6 – Core Recovery
After reaching the required depth, the core barrel retrieves an intact rock sample for geological analysis.
This fully hydraulic workflow improves drilling accuracy, extends tool life, and increases core recovery in complex geological formations.
Diamond Core Drilling Machine Price: What Determines Long-Term Value?
Many buyers compare only the purchase price. Professional drilling contractors evaluate total operating costs instead.
Several factors influence long-term investment value:
- Maximum drilling depth
- Hydraulic lifting capacity
- Engine power
- Mud pump performance
- Fuel consumption
- Maintenance frequency
- Spare parts availability
- Project utilization rate
Higher-capacity models usually complete deep drilling projects more efficiently. They also reduce rod handling time and increase daily production.
YG Machinery helps customers select equipment according to drilling depth, geological conditions, and annual workload. This ensures the investment matches actual project requirements instead of purchasing unnecessary capacity.
