Core Components and Advantages of the Solution

Solution Modules	Key Designs / Measures	Engineering Challenges Solved	Core Advantages
1. Drilling Rig Main Unit (Lightweight)	Core components such as the feed frame are made of new alloy materials.	Traditional drilling rig components are bulky and difficult to move manually in tunnels.	The main unit weight is significantly reduced, making it easier to disassemble and move.
2. Power System (Modular)	Equipped with three independent small pump stations, which can work individually or in parallel.	A single large pump station is heavy and bulky, making it inconvenient to move.	The pump station is modular, allowing for flexible combination according to drilling depth, making transportation more flexible.
3. Actuator (High Adaptability)	The power head adopts a special lubrication design to ensure reliable operation at any angle from -90° to 90°.	Drilling at various angles, including horizontal, upward, and downward angles, is required within the tunnel.	Achieves full-angle drilling, meeting the complex needs of tracking the occurrence of ore bodies within the tunnel.
4. Process Support (High Efficiency)	Equipped with two installation methods: column-mounted and rotating hydraulic support installation.	Due to limited tunnel height, traditional high-tower drilling rigs are unusable, posing safety hazards and resulting in low operational efficiency.	The lifting frame length is adjustable, adapting to low tunnels and reducing the number of drill lifts, thus improving core sampling efficiency.

Application Scenarios and Value of the Solution

This solution is particularly suitable for the following scenarios. Its core value lies in utilizing existing underground engineering to save significant costs and time associated with drilling from the surface, enabling precise exploration of the ore body:

Deep mineral exploration in metal mines: Drilling into the sidewalls or deeper within existing tunnels to explore for new ore bodies.

Underground geological support in coal mines: Used for constructing gas drainage holes and water exploration holes, and for exploring geological structures.

Production exploration and in-depth exploration: Conducting in-depth drilling near the mining area to precisely control the ore body boundaries and guide mining operations.

Comparison with Other Solutions

There are many types of drilling rigs commonly used in the market, and their application scenarios differ significantly:

Solution Type	Core Advantages	Typical Application Scenarios
Fully Hydraulic Tunnel Core Drilling Rig (This Solution)	Adaptable to confined underground spaces, capable of drilling at all angles, saving on surface engineering costs.	Deep resource exploration and geological structure investigation within mine roadways.
Crawler-type Fully Hydraulic Core Drilling Rig	Highly mobile on the surface, suitable for complex terrain.	Deep mineral exploration in mountainous and forested areas.
Portable pneumatic down-the-hole drill	Extremely lightweight, single-powered, and quick to deploy.	Shallow hole operations such as mine slope anchoring and emergency rescue projects.

Summary and Selection Recommendations

In summary, lightweight fully hydraulic tunnel drilling rig solutions, represented by the KY-1000 fully hydraulic tunnel drilling rig, are an efficient choice for solving the challenges of resource exploration in underground tunnels. Its value lies in achieving "deep drilling, accurate data acquisition, and easy relocation" in harsh underground environments.
