Core drilling machine for mining is specialized equipment used to drill into underground rock formations and obtain representative core samples. These samples allow exploration teams to examine geological structures, mineral distribution, rock characteristics, and potential ore-bearing formations before making important decisions about mine development. The mining core drilling rig needs to provide stable drilling control, sufficient lifting force, and reliable operation under challenging geological conditions. Hydraulic transmission is particularly useful because drilling and feeding operations can be controlled smoothly as geological conditions change. The available configurations cover drilling depths from approximately 180 meters to 1,100 meters, making the series suitable for both medium-depth exploration and deeper mineral investigation projects.

Hydraulic System Designed for Controlled Drilling
The full-hydraulic design is one of the main characteristics of this core drilling machine for mining. Hydraulic power is used to coordinate key drilling operations, helping operators adjust drilling parameters according to formation conditions and maintain a consistent drilling process.
The hydraulic system is also designed to work with the mud circulation system. Drilling fluid can help cool drilling tools, carry drilling cuttings away from the hole, and support effective hole cleaning during operation. This makes the equipment suitable for projects where continuous and controlled drilling performance is important.

Strong Power for Demanding Mining Conditions
Reliable engine performance is essential when a drilling machine works for extended periods in challenging environments. The series uses Yuchai engines on the smaller models and a Cummins engine on the YGX-1000 configuration.
The available engine configurations provide different power levels according to machine size. This gives the drilling system the power needed to coordinate rotary drilling, hydraulic feeding, lifting, and auxiliary functions while maintaining practical operating efficiency.
Flexible Drilling Angle
Different geological exploration projects require different hole orientations. The YGX series supports angled drilling configurations, with the YGX-400 offering a drilling angle range from 0 to 90 degrees and the larger models supporting 45 to 90 degrees.
This flexibility can be useful when exploration targets are not located directly beneath the drilling platform. Operators can select an appropriate drilling direction according to the geological target, site layout, and exploration plan.

Efficient Feeding and Lifting Performance
Drilling performance is influenced not only by rotary power but also by the ability to feed the drill string smoothly and retrieve drilling tools efficiently. The YGX series is designed with dedicated hydraulic feeding and lifting systems to support these operations.
Depending on the selected model, lifting force ranges from 12 to 30 tons, while feed force ranges from 6 to 15 tons. This range gives customers the opportunity to match machine capacity with the expected depth and drilling conditions of their projects.
Hydraulic Mud Circulation System
An effective mud circulation system is an important part of many core drilling operations. The hydraulic mud pump on the YGX series is designed to provide drilling fluid circulation during drilling.
The smaller models provide a mud pump flow range of 30–90 L/min, while the larger configurations provide 90–180 L/min. The system can assist with hole cleaning and drilling tool cooling, contributing to a more controlled drilling process.

Heat Dissipation for Continuous Operation
Mining exploration projects can involve long drilling cycles and demanding working conditions. To support stable equipment operation, the YGX series uses a combined air-cooling and water-cooling heat dissipation system.
This design helps manage heat generated during continuous operation and supports the hydraulic and engine systems during extended drilling work. Proper cooling is especially important for maintaining consistent performance when equipment is working under high loads.
Applicable Scenarios
1. Applications in Mineral Exploration
The core drilling machine for mining is primarily suited to geological exploration where representative underground rock samples are required. It can be used to investigate potential mineral deposits and understand the geological conditions surrounding an exploration target.
For mining companies, drilling information can contribute to decisions related to resource evaluation, deposit investigation, mine planning, and further exploration. The appropriate drilling configuration depends on the target depth, rock formation, project scale, and required sampling method.
2. Applications in Geological Investigation
Beyond mineral exploration, hydraulic core drilling equipment can also be used for geological investigation projects. Drilling can help engineers and geologists understand underground rock structures before construction or further development work begins.
Projects involving infrastructure, geological surveys, and other subsurface investigations may require drilling equipment that can maintain controlled penetration and operate at different angles. The flexibility of the YGX series makes it a practical option for these types of applications.
Advantages for Mining Contractors
A major advantage of this core drilling machine for mining is its full-hydraulic operating system, which provides controlled power transmission for drilling, feeding, and lifting. This can help operators adapt the machine to changing underground conditions.
The model range is another advantage. Instead of relying on one standard configuration, customers can select a drilling rig according to the scale and depth of their exploration project. The combination of different engine configurations, lifting capacities, feeding forces, and drilling ranges provides greater flexibility for equipment selection.
How to Select the Right Model?
The first consideration should be the planned drilling depth. Customers should compare the expected working depth with the available capacity of each model and allow sufficient operating margin for actual geological conditions.
The second consideration is drilling orientation. If the project requires vertical and inclined holes, the drilling-angle capability should be evaluated before choosing the equipment.
The third consideration is site and operating requirements. Engine power, machine dimensions, weight, mud pump capacity, lifting force, and feeding force should all be considered together rather than evaluated separately.
