Our factory takes pride in strict quality control and customized solutions. Each YT29A undergoes 100 hours of continuous operation testing before leaving the factory to strictly ensure product quality.
Main haulage tunnels are critical to mine transportation efficiency. The YT29A pneumatic rock drill enables fast, consistent drilling of blast holes required for tunnel expansion.
Its stable penetration helps crews maintain planned advance rates, ensuring ore transport systems can be installed without delay. This reliability is essential for large mines with tightly coordinated production schedules.
The YT29A is a heavy-duty pneumatic leg rock drill designed for medium to hard rock formations (f=8~18), capable of drilling horizontal, inclined, and upward bolt holes with a diameter range of 34-45mm and an effective economic drilling depth of 5 meters . It weighs 26.5kg with dimensions of 659×248×205mm, featuring a cylinder diameter of 82mm and a piston stroke of 60mm that delivers an impact energy of over 70J and a frequency of 37Hz . The drill can be paired with FT160A/B/C or FT170 legs based on tunnel cross-sections and can work with drill rigs for both dry and wet drilling, adapting to diverse mining scenarios including metallurgy, coal mining, and infrastructure construction .
Operation of the YT29A is streamlined for on-site efficiency. Connect the drill to a compressed air source (working pressure: 0.4-0.63MPa) and a water supply (0.3MPa) as needed for dust suppression . Select the appropriate leg model based on the working height, then adjust the propulsion force to match the rock hardness—avoid excessive force to prevent drill jamming. Routine maintenance focuses on lubrication of key components and inspection of air and water pipelines, which our team provides detailed guidance on through on-site training and manuals.
The performance leap brought by the YT29A is evident when compared to conventional rock drills. Mines previously using standard models reported a 30% increase in drilling efficiency after switching to the YT29A, with single-cycle advance rates rising from 1.8m to 2.2m . Its low air consumption (≤65L/s) reduces energy costs by 25%, while the optimized structure lowers failure rates by 40%, minimizing unplanned downtime . Operators also note reduced vibration and fatigue, addressing long-standing occupational health concerns with older equipment.
Our factory, boasting a monthly production capacity of over 200 units and a complete quality control system, adheres to ISO9001 standards and CE certifications . We integrate years of field feedback into product upgrades, ensuring the YT29A meets the rigorous demands of large-scale mining. Backed by a 7×24-hour after-sales service network and local spare parts warehouses, we guarantee 48-hour on-site response to minimize operational disruptions . For mines striving to enhance logistics efficiency and cut costs, the YT29A is more than a tool—it’s a reliable partner in meeting tight production schedules.
