ZDY-220 Hydraulic coal mine tunnel drilling machin

This series of drilling machines include three models (ZDY-220, ZDY-660 and ZDY-2000S). They are mainly used for drilling holes for water exploring and injection, gas exploring and discharging, geological exploring, bolting on slope and other drilling works. It is available of all direction position (±90°) for in underground coal mines. Adopting entire hydraulic system, it consists of main frame, pump station and operational panel. With the split type structure in the main frame, it is easy to disassemble and transportation. It suits for different drilling requirements with using high-grade alloy, PDC drill bits , large diameter spiral drill rod and core drill bits.
