Applications of Upward Pneumatic Stoper Rock Drill

Roof Bolting

Used for roof bolts, cable bolt holes, and grouting holes in underground mines.

Upward Drilling

Ideal for upward blastholes, pilot holes, and raise boring applications underground.

Tunnel Support

Suitable for crown anchor holes, pipe roof drilling, and tunnel grouting work.

Rescue & Anchoring

Reliable for emergency rescue, slope stabilization, and upward anchoring projects.

Competitive Advantage

Built for Upward Drilling

The YSP45 is specially designed for overhead drilling. Its telescopic support system reduces operator effort, improves drilling accuracy, and helps maintain straighter holes in roof bolting and upward blasthole applications.

Explosion-Proof & Safer Underground

Powered entirely by compressed air, it has no electrical spark risk and is suitable for underground mining environments. The wet drilling system also helps reduce dust and improve workplace safety.

Forged Structure, High Durability

The fully forged body and reinforced load-bearing parts provide excellent strength, impact resistance, and stable performance in damp, dusty, and high-frequency underground working conditions.

Compact & Easy to Handle

Its compact layout and ergonomic controls make the YSP45 easy to operate in narrow roadways, tunnel crowns, and other confined underground spaces.

Wear-Resistant Core Parts

Key components use high-grade alloy steel with advanced heat treatment for outstanding wear resistance, longer service life, and lower downtime in continuous underground drilling operations.

Strict Quality Control & Fast Support

Each unit is tested before delivery to ensure stable performance and sealing reliability. Standard models and spare parts are available for fast delivery, backed by professional after-sales support.
