Features of Fully Hydraulic Core Drilling Machine for Mining
1. Optimized overall structure
Integrated tower and machine, enabling quick hole layout and relocation, greatly saving manpower and material resources.
Crawler chassis with manual + remote control mode, safe and convenient.
Mast telescopic drill frame structure, no need for a drill tower, fast to carry and disassemble, with high safety.
Top-drive power head with long-stroke guide rail, cylinder propulsion, no need for repeated rod reversing, good guidance and directionality.
Small machine footprint, no foundation engineering required, green and environmentally friendly.
2. Full hydraulic transmission
Flexible layout, lightweight, easy to operate, and simple maintenance.
Stepless speed regulation, can run at high speed, stable drilling process, and low vibration.
Real-time grasp of downhole conditions through various pressures, with pressure limiting protection, high safety.
3. Adaptable drilling technology
The drill string system can ensure “full, rigid, straight”, which is conducive to hole deviation control.
Combined with thin-walled drill bits, it can achieve low torque resistance, fast cutting speed, and high drilling efficiency.
Can ensure large core diameter and high core recovery rate.
Due to the equipment structure design, the annular gap is well controlled, which is not easy to cause block falling and sticking, with few accidents and high safety.
Working Process of Hydraulic Core Drilling Machine
Preparation work: First, level the ground; use the equipment’s own system to find the level; adjust the mast angle according to design requirements; dig a mud pit, connect the mud pump, and do other preparation work.
Start drilling and lower casing: Just like building a building needs to lay a good foundation, drilling construction needs to lower the casing in advance, and the specific requirement is that the casing goes into the bedrock. The reason for lowering the casing: the surface overburden is generally soft, and in the later drilling process, there will be slag falling and collapsing, which directly affects the smooth progress of drilling. The stable crawler chassis of the equipment is conducive to casing lowering operations.
Official drilling: Hoist and connect the double-pipe drilling tool assembly to the power head, start the mud pump, and officially start drilling. Each drill pipe is 1.5 meters long. After drilling one drill pipe, the power shackle rises, then connect another 1.5-meter drill pipe, and repeat this cycle.
Grab the inner pipe and take out the core: After completing the round-trip footage, the core in the inner pipe is full. At this time, it is necessary to use a hydraulic winch to lower the fishing tool into the drill pipe with a steel wire rope. The fishing tool falls freely into the inner pipe under the action of gravity, then fish out the inner pipe, and then take out the core from the inner pipe.

How to Choose the Right Hydraulic Crawler Drill?
When selecting a hydraulic crawler drill, you shall confirm equipment configurations step by step according to project requirements, instead of judging drilling capacity merely by model names.
1. Confirm core sampling specifications
First, confirm whether the project requires BQ, NQ, or HQ core sampling. Different specifications match different core diameters, drill pipe outer diameters, and drilling tool configurations.
For example, if your project needs a larger core diameter, focus on HQ specification. If your project has low requirements for core diameter but needs to control drilling tool load, check BQ or NQ specifications.
2. Confirm target drilling depth
You shall confirm target hole depth based on specific core sampling specifications, rather than only asking “what is the maximum drilling depth in meters”.
The same drill rig delivers different drilling capacities under different drilling tool specifications. Larger specifications usually demand higher requirements for equipment lifting force, feed force, torque, and mud pump configuration.
3. Confirm borehole angle
If the project requires angled hole drilling, confirm the required borehole angle and check the angle range of the machine mast.
YG-400 drilling angle ranges from 0–90°, while YG-600, YG-800 and YG-1000 are 45–90°. The exact angle definition and applicable working conditions shall be confirmed before purchase.
4. Supply formation and drilling tool information
Formation conditions affect bit selection, drilling parameters, and mud pump configuration. When sending inquiries, provide rock type, estimated hardness, fracture zones, or water inflow conditions as much as possible.
Also confirm whether supporting drilling tools such as drill pipes, drill bits, reamers, core barrels, and wireline core sampling tools are needed.
5. Check site conditions
Although crawler equipment is convenient for relocation in mining areas, you still need to verify site passage width, ground bearing capacity, transportation routes, and loading/unloading conditions.
Check transport dimensions, total machine weight, and whether extra transport or lifting arrangements are required before purchase.
Main Factors Affecting Mining Drilling Machine Price
Mining drilling machine price is not fixed. It depends on the full set of configurations. When comparing quotations, confirm whether the quoted scope covers auxiliary equipment besides the main machine. Key influencing factors include:
Drill rig model and target drilling capacity
Engine brand, power, and hydraulic system configuration
Power head, mast and feed system configuration
Mud pump, winch and wire rope configuration
Whether drill pipes, drill bits, reamers, core barrels and core sampling tools are included
Scope of spare parts, wear parts and consumables
Whether transportation, installation, training, and after-sales service are included in the quotation
When sending inquiries, we recommend providing the information below:
Target core sampling specification: BQ, NQ, or HQ
Target drilling depth under this specification
Formation conditions and project location
Required scope of drilling tools and consumables
Destination for delivery and site conditions
Whether training or on-site technical support is needed
With the above information, suppliers can recommend suitable models and offer customized quotations with detailed configuration lists.
