RCZ452T Blast Hole Drilling Machine – High-Efficiency Mining & Construction Drilling Solution
The RCZ452T Blast Hole Drilling Machine is an advanced hydraulic DTH (Down-The-Hole) drill rig engineered for demanding mining, quarrying, and construction environments. With its integrated design and high-quality components, it achieves up to 30% lower fuel consumption and 50% reduced maintenance costs compared to traditional split-type rigs.
Designed to balance efficiency and precision, the RCZ452T meets rock drilling requirements for 115mm and 138mm bore diameters. For soft-rock operations such as coal mining, it provides a high-speed rotary feeding solution powered by a dual-stage air compressor, reaching a drilling speed of up to 3 meters per minute-a performance proven in coal mines in Inner Mongolia.
With fast penetration, effective dust control, and high mobility, the RCZ452T delivers reliable drilling performance for open-pit mining, road construction, tunneling, and other large-scale infrastructure projects.
