ZD712
Pneumatic DTH drilling rig
Using :
Before the coal mining, coal mines drilled gas drainage (discharge) holes, grouting fire prevention holes, coal seam water
injection holes, anti-burst pressure relief holes, water exploration holes, geological exploration holes and coal mine underground
drilling.
Introductions:
This model is equipped with a dual-motor rotary head and a multi-way valve with adjustable rotary speed. The rotary torque can
reach 2200N.m, which meets the needs of 76 drill pipes and 130 bores. The rotation speed can reach up to 150 revolutions, which
meets the needs of some customers for high-speed drilling in soft rock formations. At the same time, the 920 series models are
equipped with engineering tracks and plunger motors as standard, which increase the leveling function, improve the climbing and
cross-country performance of the equipment, and can adapt to complex terrain conditions. Vertical holes can be drilled for slopes
to meet the needs of different working conditions.
