As mines expand deeper underground, drilling equipment must adapt to higher rock stress and tougher conditions. The YT29A pneumatic rock drill delivers stable impact energy that supports reliable drilling in deep-level mining environments. Its dependable output helps maintain consistent advance rates, even as geological pressure increases with depth.
Developed by Shenli Machinery Pneumatic Company, a professional manufacturer specializing in rock drilling machinery with years of industry experience, the YT29A is a heavy-duty air-leg rock drill designed for medium-hard to hard rocks (f=8-18) in deep mining, tunnel excavation and anchor hole drilling. Powered by compressed air, it weighs 29kg, with a drilling diameter of 34-42mm and maximum drilling depth of 5 meters, featuring centralized operating mechanisms, flexible startup and air-water linkage for easy operation and maintenance. To use the YT29A, simply connect it to an air compressor (0.63MPa working pressure), assemble the matching drill rod and bit, adjust the air leg height according to drilling requirements, and start drilling—its integrated lubrication system ensures long-term stable operation without frequent downtime.
The difference between using the YT29A and ordinary rock drills in mines is remarkable. Before adopting the YT29A, most mines relied on traditional air-leg rock drills, which had low impact energy, inconsistent drilling speed, and high air consumption, requiring 2-3 operators per machine and achieving only 1-2 meters of drilling per hour in hard rock. Operators were exposed to high noise and strong vibration, leading to rapid fatigue and high error rates in hole position and depth. In contrast, the YT29A boosts drilling efficiency by 60%-80%—it can complete 3-4 meters of drilling per hour in the same rock conditions, reducing the required operators to 1 per machine and cutting labor costs significantly. Its optimized design reduces vibration and noise effectively, improving on-site working conditions and reducing operator fatigue and work-related injuries.
Choosing Shenli Machinery Pneumatic Company means choosing reliability, efficiency and professional support. Unlike other manufacturers, we focus exclusively on rock drilling machinery, with a complete production line, strict quality control system and ISO 9001:20015 certification, ensuring each YT29A meets high industry standards with durable parts and strong universal applicability. We provide timely after-sales service, on-site operation guidance and sufficient spare parts supply, solving any equipment problems for mines quickly to avoid production delays. In addition to efficiency improvement, the YT29A reduces air consumption by 20% compared to ordinary rock drills, lowering energy costs, and its long service life (2-3 times that of ordinary models) minimizes equipment replacement costs, bringing obvious economic benefits to mining enterprises.
For mines facing the challenges of deep excavation, the YT29A is more than a drilling tool—it is a reliable partner that enhances productivity, reduces costs and improves safety. Backed by Shenli Machinery Pneumatic Company’s professional strength, the YT29A continues to deliver stable performance in high-stress deep mining environments, helping mines achieve more efficient and economical operation.
