Basalt is one of the toughest rock types encountered in tunnel construction. The YT29A, with its high-energy hammering and durable internal components, maintains strong performance even in these demanding conditions.
Its ability to sustain impact force reduces bit wear and prevents drilling delays, helping crews maintain daily excavation targets.
As a professional factory specializing in rock drilling machinery, we introduce the YT29A Leg-Type Rock Drill—a robust solution engineered for extreme tunneling environments. Designed to excel in excavating challenging volcanic formations, this pneumatic drill combines high-impact energy with hardened internal components to sustain prolonged, efficient operation in basalt, one of the toughest rock types in tunnel construction. The YT29A operates using a simple yet powerful mechanism: compressed air drives its piston to deliver rapid, consecutive blows, while the integrated leg support provides stability and adjustable thrust. Users should ensure consistent air pressure (5-6 bar recommended), regularly lubricate moving parts, and pair the machine with quality drill rods and bits to optimize performance.
Before deploying the YT29A, mining and tunneling teams often faced frequent drilling delays, excessive bit wear, and unpredictable progress in basalt layers. Conventional drills struggled to maintain impact force, leading to extended downtime and higher tool replacement costs. Since switching to the YT29A, operators report a marked improvement: penetration rates have increased by an estimated 30–40%, bit lifespan extends significantly due to reduced vibration and consistent energy transfer, and daily excavation targets are met consistently even in dense volcanic rock. The drill’s durability minimizes mid-shift failures, allowing crews to focus on advance rates rather than equipment troubleshooting.
FACTORY
Built for resilience, the YT29A features a reinforced cylinder and optimized valve system that withstands the abrasive nature of basalt drilling. Its lightweight yet sturdy leg assembly offers precise angle control, reducing operator fatigue during overhead or horizontal drilling. The tool’s modular design also simplifies maintenance—wear parts like piston seals and gaskets can be replaced on-site with basic tools. In field tests across hard rock quarries and tunnel projects, the YT29A demonstrated reliable performance over continuous 8-hour shifts, with no loss in impact momentum. This reliability translates into lower operational costs and fewer interruptions, critical for projects on tight schedules.
We encourage contractors and mining supervisors to evaluate the YT29A for upcoming hard rock applications. Its proven ability to tackle basaltic formations ensures that drilling cycles remain efficient, supporting safer and more predictable tunneling progress.
